The Dover 874DJ3 Transformer is a 0.250 kVA, single-phase device with dual primary voltages of 240 V or 480 V and a 120 V secondary, designed to deliver 120 V from higher-voltage supplies at 50/60 Hz. Rated at 250 VA, it supports moderate-load applications where a stable 120 V output is needed from either 240 V or 480 V mains. The unit’s 1-phase configuration and 50/60 Hz compatibility make it suitable for installations that require a flexible step-down solution across different regional power standards, ensuring compatibility with equipment that operates on 120 V.
