Panel, analog quantity, communication, pulse, PID, multi-segment speed and other frequency set channel selection;



Built-in AVR, overmodulation, instantaneous stop and stop functions design, adapt to complex power grid environment;



High performance VF control algorithm in the industry can achieve stable operation with 150% load at full speed range (except zero speed);



High performance SVC control can achieve stable operation at 150% load within the full speed range of rated frequency.



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



Voltage level: single phase 220V model 0.4-2.2kw and three phase 380V model 0.75-5.5kw



• Overvoltage suppression protection: when the braking resistor is not connected, the operating frequency is automatically adjusted or the bus voltage rise is suppressed by magnetic flux braking;



• Under-voltage suppression protection (stop but not stop): can realize the function of not stopping when power is lost;



• Wave-by-wave current limiting: When the sudden load or current occurs an instantaneous spike and other abnormal conditions, the wave-by-wave current limiting protection is triggered to limit the rise of current to a certain extent, so that the current does not exceed the inverter protection value, and avoid overcurrent fault shutdown;



• Heat dissipation treatment: independent air duct design, close to IGBT power device for efficient cooling, and software built-in automatic load frequency reduction function according to temperature rise;



• Overvoltage and overcurrent fault protection;



• Input phase loss: input phase loss is detected according to bus voltage fluctuation detection. When phase loss occurs, a certain load should be carried to detect it;



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



• Short circuit fault between phases and ground: detected quickly within 20ms before operation;



• Inverter module overheating, parameter self-learning fault, current detection fault, SVC stall fault, etc.;
