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 no brake resistor is connected, the operating frequency is automatically adjusted or the bus voltage rise is suppressed by flux braking.
• 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 20ms before operation；
• Inverter module overtemperature, parameter self-learning failure, current detection failure, SVC stall failure, etc.
