This product is a micro-current measurement of power isolation sensor, the measurement method is perforated structure, no insertion loss, high overload capacity,

the input and output are not common ground, the input signal is AC micro-current, the output is RS- 485 communication interface, which can be used to measure insulation
leakage current and AC small current of AC system. The product can be widely used in insulation monitoring and AC small current detection of each circuit of AC power supply
system.
