Power supply

Input three-phase AC power supply according to the user manual

Circuit breaker

Usage:When the post equipment over current , it will be cut the power supply and protect the post equipment.
Selection:The breaking current of the circuit breaker is 1.5-2 times of the rated current of the inverter; The time characteristic of circuit breaker needs to be selected according the inverter overload protection time characteristic.

Leakage protector

Usage:Because the inverter output is PWM high frequency chopping voltage, the high frequency current is inevitable.Selection: Recommended B type special leakage protector.


In order to ensure safety, please do not close and disconnect frequently which will cause inverter failure; Do not use the closed and disconnect the contactor on the system through the power of the inverter start and stop, which will reduce the life of the inverter

Input AC reactor

Improve the efficiency factor; Improve the effect of unbalanced three-phase AC power supply on the system; Control the high order harmonics, reduce the interference of the external conduction and radiation, effectively reduce the pulse current on the rectifier bridge

Input filter

Reducing the conduction interference from the power supply to the inverter; Improve the anti-interference ability of the frequency inverter; Reduce the external conduction and radiation interference.

Braing unit and braking resistor

Use: When braking, it can effectively use the energy of the motor to achieve fast braking.
Selection:The selection of brake unit, please contact our technical staff directly, the braking resistor selection reference peripheral device selection table.

Output filter

Reduce the external conduction and radiation interference

Output AC reactor

It can effectively avoid the damage of the motor insulation due to the hidden wave voltage and reduce the frequency of the frequency converter.When the inverter to the motor connection over 100m, it is recommended to install the output AC reactor.
