1. Standard Configuration
* It has multiple protection functions such as short - circuit, locked - rotor, overload, grounding, phase - loss/imbalance, underload, TE curve, under/over - voltage, start - up timeout, pre - start acceleration trip, power loss during operation, and external faults.
* It measures electrical quantities such as three - phase current, zero - sequence current, three - phase current imbalance degree, three - phase voltage, zero - sequence voltage, three - phase imbalance degree, active/reactive power, power factor, and frequency, realizes comprehensive protection of the motor, and has the function of recording protection events.
* Active energy (kWh), Reactive energy (kVARh)
* Four configurable protection control output modes:
1. Direct start mode 2. Trip protection mode
3. Star/delta start mode 4. Circuit breaker protection mode
* Wide - range AC/DC universal power supply: AC/DC85～265V
* One RS - 485 communication interface with Modbus RTU communication protocol
* Eleven digital remote signal inputs: 7 of them have start/stop/emergency stop/communication/display control functions. Five relay outputs; 1 of them is used for device fault alarm output.
*Three-phase current measurement and SOE recording, which can be read in real-time through the communication interface. Protection parameters can be set by the display unit and communication software;
2. Optional configurations
*Expanded display unit: Real-time display of measured electrical quantities and on-site parameter setting
Six-button digital LCD display unit/Seven-button Chinese LCD display unit
*Dual RS-485 communication interfaces
*One channel of programmable DC4～20mA analog output
*Restart after voltage loss
*Profibus-DP communication interface
*DeviceNet communication interface
*Dual power supply module PDM-810SY
*External zero-sequence/leakage current transformer input for measuring zero-sequence/leakage current
*Two ways of current input, allowing users to choose flexibly according to their needs
1. Small CT input (MT optional):
Below 15 (MT25), 15 - 60A (MT100)
30A - 90A (MT150), 60A - 150A (MT250)
2. Above 150A, use standard CT (1A/5)
Note: You can only choose one from Profibus-DP, DeviceNet and dual RS-485 communication.
