Features of AM3SE 3 Phase Mv Switchgear Current Voltage Protection Relay
01
It provides B-channel AC input (standard hardware includes: three-phase protection current, two zero-sequence current and 3 voltage channels), 11 user-defined active switch inputs, and 5 programmable passive switch inputs output.
02
The working power supply supports AC/DC 220V, AC/DC 110V self-adaptation or DC 24V, DC 48V self-adaptation.
03
The external anti-jump module (can be installed on the standard guide rail), is more convenient to use with various switchgears.
04
It adopts 32-bit CPU with high performance and low power consumption, which has excellent processing ability and real-time response performance, ensuring that the CPU load rate is only less than 30% when the device is running normally.
05
It has a huge information record, including: more than 200 S0E messages, system information, and fault recording data of more than 10 seconds in total. Wave recording data includes 8 communication channels and 11 remote signaling information.
06
It provides 1 RS485 serial communication interface,and supports IEC .Besides, Modbus communication protocol is optional.
07
It provides GPS time synchronization interface and supports IRIG-B time synchronization method.
