Current-Operated Solid-State Relays for Switching AC Circuits

AC Current Switch

ACS

All models are designed for mounting in a 2” X 4” electrical wall box

Description 

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.

Applications

Direct control of AC loads, such as dryer booster fans, in response to the current of a monitored AC circuit.

Features 

Self-powered and no insertion loss

True digital switching and no leakage

Small compact size

Input / Output isolation via current transformer

Solid-state reliability

Solid, reliable mounting method

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.
