Current Sensors Model CS-150 and CSS-150 Open Loop Hall Effect Description The Models CS-150 and CSS-150 detect AC current from 1 to 150 amps and provide a solid state switched output when the current exceeds the adjustable trip point. Adjustment is made by a multi-turn trim pot. A flashing LED gives visual indication of the trip point. The CSS-150 clamps over existing wiring for easy installation. UL listed. Features · Adjustable trip range from 1 A to 150 A (split core - 1.5 A to 150 A) · Simple two wire connection · Split core for easy installation · Built in LED indicates On/Off status · Switch rated 1 to 135 volts AC or DC Applications · Sense broken belts on motors · Detect open heater strips · Sense clogged air filters · Detect burned out navigation lights · Operational status of fans, motors and pumps.

Contacts close when the current exceeds the set point. The output contacts can accept AC or DC and are not polarity sensitive. 2. The LED indicates three possible operating states: Fast Flashing indicates power is on and sensor contacts are closed. Slow Flashing indicates power is on, but sensor is below trip point and No Flashing indicates power is off or below minimum range of sensor . 3. Due to continuous process improvement, all specifications are subject to change without notice. 6120 Hanging Moss Road • Orlando, Florida 32807 Phone (407) 678-9748 • Fax (407) 677-5765 • www.fwbell.com Rev. date 09/2005 Current Sensors Model CS and CSS-150 Mechanical Dimensions All dimensions are in inches (millimeters) CSS-150 CS-150 .190 DIA. 3.000 3.000 (4.83) ( 76.20 ) (76.20) .340 (2-PLCS) ( 8.64 ) .190 DIA. .437 .330 (4.83) (11.10) ( 8.38 ) (2-PLCS.) .930 1.180 ( 23.62 ) (29.97) .590 (14.99) TRIP L.E.D.
