Features: This VFD 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 after removing screws. Fast start and stop response, large moment of force at low speed. Specifications: Model: AT1-4000X Rated Voltage: AC220V (single phase) Suitable Motor Power: 4kW Control Method: V/F open loop Output Voltage Adjustable Method: PWM control Rated Current: 20A Maximum Output Frequency Range: 0 - 400Hz TerminalFunction L,Nsingle phase AC 220V input U,V,Woutput,connect to 3-phase AC motor GNDground Package Includes: 1 x Variable Frequency Drive Note: Please note that the new type and old type of this product will be sent randomly, and make sure you will not mind before ordering.
