No setup or configuration required. Ideal for retrofit. Terminal blocks provided for easy wiring. Slowly ramps up fan speed to reduce mechanical shock and increase motor life. Safety is improved by slowly starting fan. High current, reliable solid-state output can drive up to 25-amp fan loads directly. No relays to fail. Automatically reverses fan direction to clear debris from cooler, improving efficiency.
n Proportional soft-start
n Solid State
n Auto Reversing
The FRC20 is an affordable, auto-reversing fan controller with soft-start to protect fan motors
OPERATION
When TS+ and TS- input terminals are electrically connected by either a switch or thermostat, the fan controller ramps fan on momentarily in reverse to clear debris from cooler. Fan is then allowed to spin down, and ramped back on in forward direction. Consult factory for special requirements, or other programming options.
