What you need to know
before selecting a transformer
Product Selection
You should have the following information before selecting
a buck-boost transformer:
Line Voltage: The voltage that you want to buck (decrease)
or boost (increase). This can be found by measuring the
supply line voltage with a voltmeter.
Transformer Interconnection: For three-phase applications,
interconnections of transformers should be made in a
junction box. Two or three transformers may be used
depending on an open delta (2) or wye (3) connection.
Load Voltage: The voltage at which your equipment is
designed to operate. This is listed on the nameplate of
the load equipment.
The transformers’ features,
benefits and functions
Load Amperes or Load kVA: You do not need to know both —
one or the other is sufficient for selection purposes.
This information usually can be found on the nameplate of the
equipment that you want to operate.
• UL Listed
Frequency: The supply line frequency must be the same as the
frequency of the equipment to be operated — Ingersoll-Rand
Buck-Boost Transformers operate at 60 Hertz only.
Phase: The supply line should be the same as the equipment
to be operated — either single or three-phase.
• 60 Hz operation
• 600 volt class insulation
• Short-term overload capability as required by ANSI
• Meet NEMA ST-20 sound levels
