WHAT IS A CONTROL TRANSFORMER ?
What is a Control Transformer ?
When you calculate the VA requirement of a Transformer, do you use the Primary or
the Secondary Voltage ?
When selecting the VA requirement, you use the Secondary Voltage.
Can you use a Control Transformer connected in reverse ?
Yes, a control transformer can be connected in reverse. However, keep in mind the output voltage will be less than
its rating, due to the compensation factor of the windings.
Can a Control Transformer regulate the output voltage ?
A control transformer will not regulate the voltage. Output voltage is a function of the coil’s turn ratio only, times
the input voltage.
What is the benefit of “Vacuum Impregnation” on a Transformer ?
All Hammond Control Transformers are vacuum impregnated with “VT Polyester Resin” and oven cured which
seals the surface and eliminates moisture. Impregnating the entire unit provides a strong mechanical bond and
offers protection from environmental conditions.
Explain the “VA” or “Volt Ampere Output” Rating?
The VA or volt ampere output rating designates the output which a transformer can deliver for a specified time at
its rated secondary voltage and rated frequency, without exceeding its specified temperature rise.
Insulating Materials, what are they made of and what is their purpose?
Hammond Power Solutions utilizes Mylar, Nomex and other high quality insulating materials. Insulation is used to
electrically insulate turn to turn windings, layer to layer windings, primary to secondary windings and ground.
What is the effect of “Overload”?
When a transformer is continually overloaded, excessive heat develops and the insulation system will begin to
breakdown. As a result, the life expectancy of the transformer is shortened due to the heat exceeding the rating
of the insulation system.

SECTION 1
A control transformer is an isolation transformer designed to provide a high degree of secondary voltage stability
(regulation) during a brief period of overload condition (also referred to as “inrush current” ). Control transformers
are also known as Machine Tool Transformers, Industrial Control Transformers or Control Power Transformers.
INDUSTRIAL CONTROL
TRANSFORMERS
SECTION 1
SECTION 1
CONTROL TRANSFORMER SELECTION
Selecting a Control Transformer requires that you have first
hand knowledge of the application
for the transformer, and that you
understand some basic terms
related to the selection process.
By using the following information,
you will be sure to select the Hammond Control Transformer which
best meets your application.
The Hammond PT Series
machine tool control transformers
are specifically designed for high
inrush applications requiring reliable output voltage stability.
Designed to meet industrial applications where electromagnetic
devices such as relays, solenoids,
etc. are used, the Hammond PT
series transformers maximize
inrush capability and output voltage
regulation when electromagnetic
devices are initially energized.
To select the proper transformer,
three characteristics of the load
circuit must first be determined.
They are total steady-state (sealed)
VA, total inrush VA, and inrush load
power factor.
A. The total steady state “sealed”
VA is the amount of VA that the
transformer must supply to the load
circuit for an extended length of time.
Simply add the total steady-state
VA of all devices in your control
circuit. The operating VA data of
these components is available from
the manufacturers.
B. The total inrush VA is the
amount of VA that the transformer
must supply for all components in the
control circuit which are energized
together. Some consideration to the
start-up sequence may be required.
Inrush VA should be obtained from
the device manufacturer.
C. The inrush load power factor is
difficult to determine without detailed
vector analysis of all the control
circuit components. Such information
is not generally available. Therefore,
Hammond is recommending that
a value of 40% power factor be
utilized. Although some other
control transformer manufacturers
still recommend a power factor
of only 20%, Hammond, through
recent tests conducted on many
popular brands of control devices
has determined that the 40% power
factor value is more accurate.
Once the above circuit variables
have been determined, transformer
selection is a six (6) step process.
SIX EASY STEPS
1. Determine what your Primary
(supply) and Secondary (output)
voltage requirements are, as well
as your required frequency (i.e.
60 Hz)
2. Calculate the Total Sealed VA
of your circuit. (See Step A)
3. Now calculate the Inrush
VA by adding the inrush VA of
all components being energized
together. Remember to add the
sealed VA of all components that do
not have inrush VA, (lamps, timers
etc.) as they do however present
a load to the transformer during
maximum inrush. If the inrush for
the components in your circuit are
not known, assume a 40% Inrush
Power Factor.
4. Calculate the Total Inrush VA
using one of the two methods:
A.
Total Inrush VA =
(VA sealed)2 + (VA inrush)2
OR
B.
Total Inrush VA =
VA Sealed + VA Inrush
Note: method B will result in a slightly
larger transformer being selected.
© Hammond Power Solutions Inc.
5. If the nominal supply voltage
does not fluctuate more than 5%,
then reference the 90% secondary
voltage column in the Regulation
Data Table for the correct VA
rating.
If the supply voltage varies
upwards of 10%, the 95% secondary
voltage column should be used to
size the transformer.
Current standards require
electromagnetic devices to operate
reliably at a minimum of 85%
of their rated voltage. However,
contact life may be affected with
continuous start-ups at that voltage
level. Therefore, the minimum 85%
secondary voltage column should
only be used as a reference.
6. Using the regulation data tables
below, select the appropriate VA
rated transformer:
A) with a continuous VA rating
that is equal to or greater than the
value in Step 2.
B) with a maximum inrush VA
equal to or greater than the value
obtained in Step 4.
To d e t e r m i n e t h e c o r r e c t
Hammond Transformer and its
Catalog Number, just refer to
the tables in this catalog for the
voltage ratings, frequency and
corresponding VA required.

It is recommended that a Control Transformer be
sized at a 40% Power Factor. Some components
in a circuit, such as electromagnetic devices,
typically operate at that level due to their
inherently lower power factor. Selecting a
transformer at 40% Power Factor will more than
adequately size the unit for all the various loads
in the circuit.

PH Series Control Transformer - Applications
The Hammond “PH” series of machine tool transformers are specifically designed for high inrush applications
requiring reliable output voltage stability. Designed to meet industrial applications where electromagnetic devices
such as relays, solenoids, etc. are used, the Hammond “PH” series transformers maximize inrush capability and
output voltage regulation when electromagnetic devices are initially energized.
STANDARDS
Hammond Industrial and Machine Tool Control and
Instrument Transformers meet or exceeds the standards
established by UL, CSA, IRC, ANSI, NEMA.

At HAMMOND, we rate the VA capacity of our transformers at the output ..... where
it counts. Other transformer manufacturers rate their capacity on the input side of the
transformer, which can result in a 5% to 20% lower actual VA at the output.

SECTION 1
The Hammond DIN rail mount “PT” and “PH” series of machine tool transformers are designed to meet the
requirements for ‘panel mounted’ industrial control applications. This line offers the same features as our standard
PT and PH units except the base has been configured for mounting on DIN rail.
Hammond is pleased to introduce the NEW ‘PTD’ and ‘PHD’ series . . . the first DIN rail mountable industrial
control transformers offered in the market. The benefits of the DIN rail mounting includes:
• No incorrect back-plate holes.
• Flexibility in locating the transformer virtually anywhere in the panel.
• No drilling necessary.
• No metal shavings to dispose.
• Substitute or replace any transformer quickly and efficiently.
• All products installed in the control panel can now be bench work assembled.
• All the same great features of the PT and PH series with the ease of DIN rail mounting.
• Optional ‘anti-vibration’ bracket for high vibration applications and long range shipments.

Notes:
(1) Secondary fuse clips for 13/32 x 11/2" midget fuse are standard on all single secondary voltages.
(2) Uses one “triple” pole fuse block containing: two rejection clips for the primary and one single midget
(13/32" X 1 1/2") fuse clip for the secondary. This will allow for the fusing of most transformers
containing multiple secondary voltages.

Notes:
(1) Secondary fuse clips for 13/32 x 11/2" midget fuse are standard on all single secondary voltages.
(2) Primary Dual Rejection/Secondary Midget fuse kits (-3) are stocked in the following voltage combination:
Group AA (PT___ MQMJ)
> Primary 240/480 volts, Secondary 120 volts
Group CC (PT___QG)
> Primary 240/480 volts, Secondary 24 volts
Group A (PH___ AJ)
> Primary 600 volts, Secondary 120 volts
Group PTD-AA (PTD___ MQMJ)
> Primary 240/480 volts, Secondary 120 volts
Group PHD-A (PHD___ AJ)
> Primary 600 volts, Secondary 120 volts
(3) Uses one “triple” pole fuse block containing: two rejection clips for the primary and one single midget
(13/32" X 1 1/2") fuse clip for the secondary. This will allow for the fusing of most transformers
containing multiple secondary voltages.
Voltage Links
Factory Installed Secondary Fuse Kits
• Voltage links are separately packaged for
user installation to ensure links are installed
on the correct voltage combination. The
links are included at no charge.

Recommendations For Overcurrent Protection
SECTION 1
UL AND CSA (NORTH AMERICAN) STANDARDS
North American standards, including UL 508, National Electric Code 450 and the Canadian Electrical
Code Part I, require overcurrent protection on all control circuit transformers. There are two options for
overcurrent protection:
Option 1
Provide an overcurrent device in the primary circuit rated to the current of the transformer. The
overcurrent limits are as follows:
Primary 9 amps or more;
Primary 2 to 9 amps;
Primary less than 2 amps;
no more than 125% of rated current.
no more than 167% of rated current.
no more than 300% of rated current for power circuits.
no more than 500% of rated current for control circuits.
This method is considered less desirable as start-up inrush to the transformer can frequently
surpass the current rating of the device and result in nuisance interruptions.
Option 2
The second option is to install overcurrent devices in both the primary and secondary circuits of the
transformer. In this option, the secondary device must be rated no more than 125% of rated current of
the transformer and the primary no more than 250%. CEC permits 300% overcurrent on the
primary for this option.
In both options listed, it is recommended that time delay fuses be considered to avoid unnecessary
interruptions.
Secondary
The overcurrent protection listed below, in amperes, is 125% of the rated current of the transformer. Choose
the next higher fuse rating if these numbers do not correspond with standard fuse selections.

SECTION 1
To assist in the selection of fuses, the following chart recommends the maximum primary fuse rating in
amperes. The first number shown is the maximum overcurrent protection when the primary current is less than
2 amps and the overcurrent protection device is rated for 300%. The second number shown (in brackets) is
recommended when the primary is less than 2 amps and the overcurrent device is to be rated at 500% of rated
current. Where only one number is indicated, the primary is 2 amps or more and one rating of over current
protection is shown as optimal. Choose the next higher fuse rating if these numbers do not correspond with
standard fuse selections.

SECTION 1
IEC (EUROPEAN) STANDARDS
IEC (European) Standards are very different from UL (North American) standards including fuses and
fuse selection guidelines. As the electrical characteristics of these fuses are different, UL and IEC rated fuses
are NOT interchangeable. Of significance is the time current characteristics. Fuses built to North American
standards DO NOT MEET European Standards.
Unlike North American standards whereby overcurrent protection is to be 125% of the rated current of the
transformer (25% derated), no derating is required for IEC Fusing applications.

SECTION 1
Hammond is pleased to introduce a line of specialty control transformers ideally suited for general
purpose, industrial, light duty loads. Designed for applications where high inrush or machine tool duty are not
necessary, the SL control transformer offers an efficient and economical solution. These units are well suited for
HVAC applications, signal and alarm systems, small motors, lighting and circuit isolation.
The SL control transformer is an open style unit with molded terminal blocks, but available with a full array
of features including 10 fusing options, multiple primary and secondary voltages and optional clear plastic ‘finger
safe’ terminal covers.
For an economical approach for control transformers, the SL is the transformer of choice.

(1) Uses one “triple” pole fuse block containing: two rejection clips for the primary and one single midget
(13/32" X 1 1/2") fuse clip for the secondary. This will allow for the fusing of most transformers
containing multiple secondary voltages.
Secondary Fuse Kits
Voltage Links
To protect the transformer from the load,
secondary fuse kits are available. Fuse clips for
either 1/4” X 1 1/4” fuses or 13/32” X 1 1/2” fuses
are optional. Both are suitable for single secondary
SL series transformers. Secondary Fuse Kits consist
of all necessary fuse clips, mounting hardware and
voltage links. Fuse kits are easy to install on the
terminal block (see diagram below). Fuses are then
easily snapped into place. (Fuses not included).
Voltage links are separately packaged for user
installation to ensure links are installed on the
correct voltage combination. The links are included
at no charge.
