Product details

The ACS products are solid-state current switches with N.O. triac outputs to control high current line-voltage AC loads. The ACS 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.

Panasonic is the exclusive distributor of Atmosphere products in the US

Technical Documents


The ACS can operate a duct booster fan directly. These devices sense when the interlock device is drawing 1 Amp of current and then closes the output switch to activate the duct booster fan. When the interlock device turns off and the current drops below the threshold, the output switch will open again (with a delay for the ACS-5, 10 & 15). The device output can switch 120 Vac loads up to 2.5 Amps.
