This Variable Frequency Drive uses unique control method to realize high moment of force, high accuracy and wide speed regulating range driving, with high performance. It has good anti-trip performance and ability to adapt to rough power, temperature, humidity and dust interference, greatly improved stability. By optimizing PWM control technology and electromagnetic compatibility, it satisfies users’ requirement of low noise, low electromagnetic interference. Simple to operate and wire, connect to wires by screw terminals which are more convenient. Designed with large heat sink for better heat dissipation. This variable frequency drive uses unique control method to realize high moment of force, high accuracy and wide speed regulating range driving, with high performance. Large heat sink for better heat dissipation. Power Source Phase: Three-phase. Rated Voltage: Three-phase AC380V. Suitable Motor Power: 4kW. DC Power Supply Type: Voltage type. Control Method: V/F closed loop. Output Voltage Adjusting Method: PWM control. Maximum Output Frequency: 400Hz. Weight: 1.5kgapprox. When adjusting parameter, the variable frequency drive must stop working, otherwise it will not be able to save parameter setting.
