Atmosphere AC Current Switch - No delay

The ACS-0 is a solid-state current switch with N.O. Triac outputs designed to control high-current line-voltage AC loads. The ACS-0 model has a factory set trip level of approximately 1 Amp and requires no field adjustment for easy installation. Internal circuits are powered by induction from the line being monitored and is cULu certified.

Design Features:

• Self-powered and no insertion loss
• True digital switching with no leakage
• Small compact size
• Input / Output isolation via current transformer
• Solid-state reliability
• Solid, reliable mounting method

Applications:

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

Specifications:

• Maximum Core Current: 50 Amps
• Operating Temperature: 0 to 40°C (32° to 104°F)
• Trip Set-Point: Approximately 1 Amp
• Enclosure Size (H x W x D): 49 x 87 x 25mm (1.95” x 3.45“ x 1”)
• AC Conductor Hole: 20mm (0.8“) Diameter
• Switch Rating: 120 Vac @ 2.5 Amps Max.
• Turn on time: <200 mS
• ACS-0 turn off time: 0 minutes (factory set)
• Operating Humidity: 0 - 95% RH non-condensing
• Material: UL 94V-0 flammability rated ABS Insulation Class 600V
• Mounting Holes: 2 x 5mm holes spaced 76mm on base (2 x 0.19” holes spaced 3” on base)
• Switch Type: Solid-state triac
• Off-state Leakage: <1 mA

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.
