Current Sensors SCC and SCV Open Loop Hall Effect Model Description The SCC Series provides either a 4-20mA or 0-20mA unipolar output proportional to DC current. The SCV Series provides either a 0-5V or 0-10V unipolar output proportional to DC current. The SCC and SCV clamp around existing wiring for easy installation. All models work with AC or DC operating voltage. All models are panel mounted, feature jumper range selection and are UL listed. Features • Jumper selectable ranges • Split core for easy installation • Wide supply voltage range • Output scaling for common data acquisition systems 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.
