Micron - Buck-Boost Transformers for Voltage Regulation
Micron's Buck-Boost Transformers are specialized devices designed to efficiently modify voltage levels to optimize the operation of electrical equipment. These transformers are compact, single-phase units belonging to the 600-volt class and are equipped with dual primary and secondary windings, allowing them to function both as isolation transformers and autotransformers. Typically employed to adjust voltages in applications from 12 to 48 VAC and ranging in power capacity from 50VA to 7.5Kva, these transformers are ideal for motor operation rather than motor control circuits or fluctuating line voltage corrections. The installation on grounded systems demands careful attention to resulting voltages, making these units suitable for specific configurations such as a 208 grounded wye/120 system. To achieve 240/120 volts with a midpoint ground, a standard two-winding transformer is necessary. Micron offers a 1-year warranty on these transformers, underscoring their commitment to quality and reliability.Single and Three Phase Applications – 60Hz
Micron’s Buck-Boost Transformers are used to provide an economical method of decreasing (bucking) or increasing (boosting) voltage to a rating more suitable for efficient operation of electrical equipment.
Buck-Boost Transformers are small Kva, single-phase, 600-volt class insulating transformers with dual primary and secondary windings. If wired as an isolation transformer, they can provide for applications requiring 12, 16, 24, 32, or 48 VAC from 50VA to 7.5Kva. However, they are usually connected as autotransformers by utilizing one unit for single-phase applications and either two or three units banked for three phase operation. They are primarily used for motor operation and should not be used for motor control circuits, to correct fluctuating line voltage or to obtain a neutral on a delta system. These applications require transformers especially designed for these specific applications.
When installation is to be made on a grounded system, consideration must be given to the resulting voltage. Thus, on a 208 grounded wye/120 system the voltage can be boosted to 240 volts but the voltage to ground will be 139 volts. If 240/120 volts with a midpoint ground is needed, a standard two-winding transformer must be used.
Micron’s Buck-Boost Transformers come with a 1-year warranty.
