Select one of three ranges by moving the jumper on the device to switch between 10A,20A and 50A.This sensor outputs 0-5V directly and requires no power supply. The signal is proportional to the average current and vary slightly from the results shown on an RMS measuring ammeter, depending on the load.
The new clamping / split core current transformer allows installation without interrupting the high voltage wiring. Add a second wrap of the high voltage cable to double the output signal for a given current.
