EP2-1 3- PHASE SEQUENCE PROTECTION RELAY
Switching Mode Power Supply architecture
High immunity to inverters high frequency noise
Can detect power source phase reversal before motor start, also can detect Phase-loss and unbalance while motor operating or before motor start
Suitable for main power source and motor starter circuit to prevent damage from insufficient phase or phase reversal
Phase sequence detection- Output contact Release while phase reversal
Phase-loss detection – 3sec fixed tripping delay
3-phase voltage balance decetion – 3sec fixed tripping delay
1sec fixed reset delay
Install on DIN rail and no socket require
