Clamp style split core current sensor,
AC input jumper to select scale from 10A, 20A, 50A.
Output is proportional 0-5 VDC

Features:

Self powered, no external power supply required.
0-5VDC output, connects directly to automation systems.
One sensor for three ranges, jumper selection.
Low cost, replaces digital status relays.

The CS Current Sensors are solid state transducers that do not need any external voltage.
Perfect for measuring current of fans, compressor, pumps and may other HVAC equipment. The clamping/split core configuration allows for easy installations without interrupting the high voltage wiring. If input current is very low and more sensitivity is required, it is possible to add a second or third wrap of the high voltage cable to double or triple the output signal for a given current.

Full range of measurement is set by the jumper position

Output is always 0 to 5 VDC  according to the maximum range selected by the jumper






Ex:   Output Signal: 1~5VDC; proportional to average current

If the Jumper is removed, the CT will have a range of 0-10Amp  with an output of 0 to 5Vdc  in this setting   5 VDC = 10Amp
If the Jumper is set to 0-20Amp the maximum output of 5 VDC = 20Amp
If the Jumper is set to 0-50Amp the maximum output of 5 VDC = 50Amp
