Dongan 33-250-PM, single-phase control transformer, 0.250 kVA

The Dongan 33-250-PM is a single-phase control transformer designed to step down line voltage to a lower voltage for industrial control circuits, such as relays, contactors, and programmable logic controllers. It is commonly used in manufacturing, HVAC, and process control applications where reliable 120 V control power is needed from a 240 x 480 V primary supply.

The Dongan 33-250-PM is a single-phase control transformer rated at 0.250 kVA. It operates at 50/60 Hz with a primary voltage of 240 x 480 V and a secondary voltage of 120 V. The unit weighs 9 lb and measures 4.25 x 3.75 x 4.500 inches. It is part of Dongan's Series 33 Control line.

To select the correct Dongan control transformer, first determine the required secondary voltage and VA rating for your control load. The 33-250-PM provides 120 V at 0.250 kVA. Verify that the primary voltage matches your supply (240 x 480 V) and that the frequency is 50/60 Hz. Always size the transformer to handle the inrush current of connected devices.
