Three Phase
The RF3 Series are three-phase (6 SCR) phase-fired SCR Power Controls designed to deliver maximum power control with all the features normally found in much larger units.
Utilizing only four frame sizes, these units are conservatively engineered for years of trouble-free service while providing the benefits of precise, reliable control for your electrical process.
The RF3 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, 3 Phase, 50/60 Hz. Other voltages are 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 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. The optional blown fuse indicators are also available.
