The DPC-21 electric motor intelligent monitoring device is independently developed and produced by our company. It can be installed in high-voltage switchgear with a distribution level of 10kV or below, and can also be installed as a group screen for motor protection.

Basic protection: Specific function selection table for different protected devices and protection requirements.

Communication: Can be equipped with dual RS485 ports, or can be configured with one CAN and one RS485 interface.

Telemetry: measurement of three-phase voltage, three-phase current, zero sequence current, active power, reactive power, power factor, apparent power, frequency, positive and negative sequence voltage and current, four quadrant electrical energy, and 31st harmonic.

Fault recording: Save 64 points per cycle for 10 cycles, collect three-phase voltage or three-phase current. And it can display waveform graphics through LCD.

SOE event records and operation report records (1000 records).

The product meets the standard: the device can withstand the pulse interference test of attenuation oscillation waves with frequencies of 1MHz and 100KHz specified in GB/T14598.13 (the common mode voltage amplitude of the first half wave is 2.5KV, and the differential mode is 1KV); The device can withstand the strict level IV electrostatic discharge interference test specified in GB/T14598.14;
