Dongan Electric Manufacturing Co. 50-0050-053 Control Transformer is a single‑phase transformer with a 240–480 V input and a 50/60 Hz operating frequency. It is designed to provide control power for panel-mounted devices such as relays, contactors, timers, and signaling gear within electrical control systems. Identified by model 50-0050-053, it can be sourced for replacement or integration alongside other Dongan components in equipment. When wiring into a panel, verify that the incoming supply matches the 240–480 V range and that the transformer’s secondary voltage and power rating meet the control circuit requirements.
