Series 7 Power Controllers
Series 7 DIN Rail Mount Power Devices
Series 7 Power Devices put
12 to 80 Amps in a DIN rail
mount package that
provides precision machine
control for heater bands,
cartridge heaters, and other
resistive loads.
• DIN Rail or Wall Mounting
• Zero Crossing Control
• AC/DC ON-OFF or mA Proportional Inputs
• SCR or Triac Version
• No Need for External Wire Crimping
Introduction
The Series 7 Power Device family features a sleek design and robust performance
specifications which ensure that your tough heating requirements are surpassed. These
devices were developed to control resistive heating loads using the time proportional SSR
driver output or the linear output from a temperature controller. Specifically tuned to ensure
quick temperature ramping, precise operating control, and immediate temperature stabilization, all these features mean better product homogeneity, less wasted time and less scrap.

Thermal Protection Option
When the junction temperature reaches 125°C (257°F), a separator inhibits the command
signal and turns on the OH LED indicator. Once the heat sink temperature becomes
acceptable, the command signal is again enabled and the OH LED is turned off.

Time
In the On-Off control mode,
the output of the contactor
turns on only when the input is
turned on and the supply voltage is at a zero-crossing point.
If the input is turned on at a
non-zero point, the contactor
will simply wait for the next
zero-point to turn on. Unlike a
mechanical relay, the Series 7
with On-Off control eliminates
electrical switching disturbances and audible noise.

The Fast Cycle control mode
is a zero-crossing firing mode
that uses a fixed 100-cycle
time base for control. For example, 50 cycles on and 50
cycles off results in a 50%
output. Fast Cycle control is
best for loads that need the
slower, less frequent switching (i.e., resistive loads).

Single Cycle control mode is a
zero-crossing firing mode that
uses a variable time base (ontime plus off-time) for control.
Based on the command level,
the time base is kept at a minimum, which improves control
compared to the Fast Cycle
control mode. For example,
one cycle on and one cycle off
results in a 50% output. Three
cycles on and one cycle off
results in a 75% output. Single
Cycle control is best for loads
that require faster, more precise control (i.e., low thermal
inertia loads).

Power/nominal current conversion
The following formulas are provided to simplify model selection. These formulas enable you
to calculate the nominal current of each SSR when the total load power is known. The load
must be resistive so that in the following formulas, the cos ø will be considered equal to 1.
The formulas related with the three phase application are referred to a balanced three phase
system only.
Single Phase Connection
I RMS =
where:
P
VRMS
P = Power (in Watts)
VRMS = Phase to neutral or phase to phase voltage
IRMS = Nominal line current
Three Phase Without Neutral Connection (Star or Delta Application)
I RMS =
where:
P
VRMS • 3
P = Total load power (in Watts)
VRMS = Phase to phase voltage
IRMS = Nominal line current
Three Phase With Neutral Connection (Star Application)
I RMS =
where:
P
VRMS • 3
P = Total load power (in Watts)
VRMS = Phase to neutral voltage
IRMS = Nominal line current
Heat Generated by the Solid State Contactors
Full Load Current x 1.2 volts* x # of Legs of Control = Watts
*1.8 volts for 7PT
Example 7PE calculation: 60 amps x 1.2 volts x 2 = 144 Watts
