All models are designed for mounting in a 2” X 4” electrical wall box
The ACS-0 and ACS-5 products are solid-state current switches with N.O. triac outputs to control high-current line-voltage AC loads. The ACS-0 and ACS-5 models have a factory set trip level of approximately 1 Amp and require no field adjustment for easy installation. Internal circuits are powered by induction from the line being monitored and all models are cULu certified.
Self-powered and no insertion loss
True digital switching and no leakage
Small compact size
Input / Output isolation via current transformer
Solid, reliable mounting method
Direct control of AC loads, such as dryer booster fans, in response to the current of a monitored AC circuit.

Dryer Booster Fan Operation
The ACS-0 and ACS-5 can operate a dryer booster fan directly. These devices sense when a clothes dryer is drawing 1 Amp of current and then closes the output switch to activate the dryer vent booster fan. When the dryer cycle is complete and the current drops below the threshold, the output switch will open again (with a 5 minute delay for the ACS-5). The device output can switch 120 Vac loads up to 2.5 Amps.
