BUCK BOOST TRANSFORMERS
MGM provides buck-boost transformers as a simple and economical way to correct off-standard voltages in sizes up to 10 kVA. When the supply voltage is constantly too high or too low, (usually more than 55%), the equipment fails to operate at maximum efficiency. Buck Boosts are most commonly used for 240V equipment in a facility with 208V service or vice versa.
Buck Boost transformers are used in a number of different applications including lighting, motors, pumps, HVAC and circuit control.
Standard features for Buck Boost transformers include:
- Ratings from 50VA to 10,000VA
- 50/60 Hz frequency
- Encapsulated core & coils in a combination silica sand and resin compound
- Insulation system: 115°C rise
- UL listed & CSA certified
- Three standard voltage groups:
- 120/240-12/24
- 120/240-16/32
- 240/480-24/48

3 PHASE SYSTEMS
A single unit is used to buck or boost single phase voltage — however two or three units can be used to buck or boost three phase voltage.
The number of units to be used in a three-phase installation depends on the number of wires in the supply line. If the three-phase supply is 4 wire Y, use three buck-boost transformers. If the 3-phase supply is 3 wire Y (neutral not available), use two buck-boost transformers.
Please reach out to an MGM representative to understand how to use our Single Phase units in a Three Phase application.

Benefits
CORRECTS CRITICAL VOLTAGE MISMATCHES
With nearly two-thirds of all electrical loads being A.C. motor loads, maintaining the proper voltage is very important. If the supply line voltage is not maintained, motor winding current is increased causing reduced motor torque and escalating motor temperature, all of which results in the rapid loss of insulation life expectancy. Anytime you have a lower than standard voltage, equipment damage and failure can result.
Buck-boost transformers are an economical way to correct this potentially very serious problem. Anytime a line voltage change in the 5-20% range is required, a buck-boost transformer should be considered as your first line of defense.
