Tính năng

• Overcurrent suppression protection: real-time current monitoring, automatically limit the current to no more than the overcurrent suppression point;

• Overvoltage suppression protection: When the brake resistance is not connected, the operating frequency can be automatically adjusted or the magnetic flux braking can ensure that the AC drive will not cause overvoltage protection due to high bus voltage during operation;

• Undervoltage suppression protection (instantaneous non-stop): It can realize the function of instantaneous power loss without stopping；

• Wave-by-wave current limiting: When the sudden load or abnormal conditions such as momentary spikes in the current occurs, it will trigger the wave-by-wave current limit protection, which can limit the rise of the current to a certain extent, so that the current does not exceed the protection value of the inverter, and avoid reporting overcurrent fault and shutdown；

• Heat dissipation treatment: Independent air duct design, close to the IGBT power device efficient cooling, while the software built-in automatic reduction of carrier frequency according to temperature rise；

• Overvoltage, overcurrent fault protection；

• Input phase loss: Detect input phase loss based on bus voltage fluctuations. When phase loss occurs, a certain load is required to detect it；

• Output phase loss: Output phase loss fault can be quickly detected before and during operation；

• Phase to phase short circuit and short circuit to ground fault: quickly detected within 10ms before operation；

• Inverter module overtemperature, parameter self-learning failure, current detection failure, SVC stall failure, etc;
