Two Phase

The ZF2 SSR Series are zero-fired Solidstate Relay (SSR) Power Controls designed to deliver maximum power control with the reliability normally found in much larger units. Like all relays, the SSR requires relatively low control-circuit energy to switch the output state from OFF to ON, or vice versa.

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 ZF2 Series accepts all standard voltage and current command signals or a remote potentiometer input. Standard operating voltages are 120, 240, 400, 480 & 575 VAC, 3 Phase, 50/60 Hz. Other voltages are available.

Multi-turn zero and span adjustments are provided for matching the SCR power control to the command signal. The command signal indicator's (green) flash rate provides a visual indication of the output voltage.
