DCPF3 (SCR) 350 A

The DCPF3 Series are three-phase, phase-fired SCR Power Controls designed to deliver DC current with all the features normally found in much larger units. Utilizing HDR's field-proven circuits, these units are conservatively engineered for years of trouble-free service while providing the benefits or precise, reliable control for your electrical process. The DCPF3 Series accepts all standard voltage and current command signals or a remote potentiometer input. The 4-20 mA command signal is optically isolated. Standard input voltages are 120, 240, 400, 480 VAC, 3 Phase, 50/60 Hz. Other voltages are available.

The output DC voltages is approximately 90% of the input AC voltage. Multi-turn zero and span adjustments are provided for matching the SCR power control to the command signal. Control power and command signal indicators are provided as a means for trouble-shooting. The control power indicator (red) indicates power has been applied to the unit. The command signal indicator's (green) brilliance is proportional to the output voltage.
