UBZ-302 protects the electric motors in the following alarm situations: - Low quality power supply voltage: not allowable voltage surges and fluctuations, phase loss, wrong phase sequence, phase imbalance of phase/line voltage, phase coincidences (short circuits); - Mechanical ovmore...
Relays with built—in MCU (Micro Processor Control Unit) Environment operational temperature (-25°C to +70“ C) Common use of the Screw type & Tunnel type Applicable to the inverter circuit (20—2O0 Hz) Mounting options : 35mm Din-rail or Screw Fail safe operation. FEATURES Mmore...
In mPRO-200 the protection feature is based on mathematical model of motor thermal image. The motor thermal overload protection function calculates the heat accumulated in the rotor and stator based on the effective heating current , integrated over a time. The relay approprmore...
