Halco ES-TB325-01 Step Down Auto Transformer 480V To 208V Or 347V To 150V Or 277V To 120V (74120)

This stepdown autotransformer converts common industrial supply voltages down to the utilization voltages LED high-bay fixtures expect. Three step-down configurations are supported: 480V to 208V, 347V to 150V, and 277V to 120V — letting one accessory serve facilities on any of the standard commercial and industrial supply schemes.

The unit is a 325VA type-A autotransformer built for field installation alongside compatible fixtures. It pairs directly with Halco's Hoverbay Round Highbay and Essential Round Highbay products, giving warehouses, gyms, big-box retail, and industrial showrooms a straightforward path to run 120V- or 208V-input LED high-bays from a 277V, 347V, or 480V panel.
