The SZT15-420E AC current transducer provides real-time isolated measurement of AC current in the grid or circuit and converts it to a 0-5V/0-10V or 4-20mA DC current output signal. It can be mated with various AD and constitute various digital centralized acquisition systems. Or output to the PLC to form an automatic control system, or to match the traditional analog and digital indicating instruments, display the measured value.

Working principle:
1. Based on electromagnetic induction, inductive current will be generated when the current in the circuit changes. Transform large current into standard small current through transformer,
2. Through relevant signal processing circuit and output control circuit, the dc current signal of 0-5/10v or 4-20ma can be output and transmitted to the next level system.
