MODEL ZF2 SERIES
POWER CONTROLS
 
Three-Phase (3-Wire Only) Zero-Fired Models
Rated 15 - 70 Amperes
 

The ZF2 Series are three-phase, zero-fired Solid-State 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 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.
