Description：

【Connection way】Input：220VAC(+/-5%) 1 or 3phase（for single-phase input, just connect the input wire to the R and S terminals）   Output：3phase 220v. Frequency：0-50hz/60hz. 0-3200hz
【Multiplex terminal】Unlike other inexpensive VFDS, this VFD has two sets of terminal functions,Rich of digital and analogy control terminals for versitile control,optional MODBUS (RS485) extension,diversified parameter setting
【Safety performance】Take advantage of various protection ways such as Motor short-circuit detection at power-on, output phase loss protection, over-current protection, over-voltage protection, under-voltage protection, overheat protection, overload protection and etc.
【Good Noise Control】The product has the advantages of low noise and low electromagnetic interference, which are achieved by the excellent PMW control technology and component compatibility design. There is enough space for cooling between each component, and the product casing is designed with multiple holes, the above features can make this VFD have a longer service life.
