RF1 Series Overview

The RF1 Series are the single-phase (2 SCR) phase-fired SCR Power Controls designed to deliver maximum power control with all the features normally found in much larger units. These units are conservatively engineered for years of precise, reliable control for your electrical process.

The RF1 Series accepts all standard voltage and current command signals or a remote potentiometer input.  The 4-20 mA command signal is optically isolated. Standard operating voltages are 120, 240, 400, 480 & 575 Vac, 1 Phase 50/60 Hz. Other voltages available.

Multi-turn zero and span and over-current adjustments are provided for matching the SCR power control to the command signal.  Control power,command signal and blown fuse 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. Optional blown fuse indicators are available.


Primarily used to control transformer coupled RF induction loads
