  • This device is an electrical isolation transducer of single-phase active or reactive power and power factor measurement. Its input signal is completely isolated from the output signal. Output the linear standard analog signal, can be switched to active or reactive power factor measurement through the internal switch. The product can be widely used in electric power, communications, railway, industrial control and other fields.
