Step-down transformer (480/277/240/208 to 120V)

208/240/277/480V to 120Vac, dual hub, 50VA UL Listed transformer. Used for monitoring 480V delta services and powering 120V accessories from higher voltage systems.

Transformers provided by eGauge are 50VA (50 watts limit at 1.0 power factor, lower wattage when power factor < 1). They are intended to be used for powering a small amount of equipment provided by eGauge. Attempting to supply loads ~50VA or higher will cause the transformer to trip and require a manual reset.
