Our engineers will calculate the right transformer based on your equipment list and existing electrical service.
Free sizing assistance β tell us your equipment and voltage, we'll match the transformer
Phoenix Phase Converters stocks three-phase dry-type transformers from 3 KVA to 150 KVA in three voltage configurations: 208β480V, 240β480V, and 208β240V. These general-purpose transformers handle step-up and step-down conversion between common industrial voltages. Dry-type construction eliminates oil maintenance and environmental concerns, while UL listing ensures code compliance.
Whether you're converting 480V three-phase to 208V for equipment, stepping up 240V to 480V for a motor, or bridging between 208V and 240V systems, we have the right transformer in stock. Select your KVA and voltage above, or call (800) 417-6568 for sizing help.
