The ZF3 Series
models are three-phase (3 or 4 wire) zero-fired Solid-State Relay
(SSR) Power Controls designed to deliver maximum power control with
all 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 ZF3 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.
