The PF1 Series are single-phase, phase-fired Solidstate Relay (SSR) Power Controls designed to deliver maximum power control with the reliability normally found in much larger units. Utilizing only two 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 PF1 Series accepts all standard voltage and current command signals or a remote potentiometer input. Standard operating voltages are 120, 240, 400, 480 and 575 VAC, 50/60 Hz. Other voltages are available. Solidstate Relay type controllers are not recommended for driving transformers.
Multi-turn zero and span adjustments are provided for matching the SCR power control to the command signal. The command signal indicator's (green) brilliance is proportional to the input command signal.
