SolaHD Buck-Boost Transformers are designed to correct low or high line voltage by a fixed percentage, helping electrical equipment operate at its intended voltage without replacing the existing power source. They offer an economical solution for improving equipment performance, extending equipment life and reducing downtime caused by improper supply voltage.
Unlike a traditional isolation transformer, a buck-boost transformer is commonly connected as an autotransformer, allowing a relatively small transformer to correct voltage by approximately 5% to 27% while delivering significantly more load current than its nameplate kVA would suggest.
These transformers are commonly used for machinery, HVAC equipment, industrial automation systems, commercial equipment, lighting systems, motors and other electrical loads where incoming voltage consistently runs above or below the equipment's required operating voltage.

A buck-boost transformer is a small transformer designed to increase (boost) or decrease (buck) supply voltage by a fixed percentage. Rather than replacing the incoming power source, it adjusts the voltage to better match the equipment's required operating voltage.
Choosing the proper buck-boost transformer requires knowing:
Because buck-boost transformers are connected differently than standard isolation transformers, proper sizing depends on the voltage correction required and the connected load. Always verify the transformer selection before installation.
Buck-boost transformers are frequently used when equipment rated for 230 volts must operate from a 208-volt supply, or when 460-volt equipment must operate from a 480-volt system. They are also used to compensate for voltage drop caused by long conductor runs.
If you're unsure which SolaHD Buck-Boost Transformer you need, contact Wallco with your available voltage, required equipment voltage, phase, frequency and load current. Our team can help identify the appropriate catalog number for your application.
