Description This VFD uses unique control to realize high moment of force, high precision 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 heat sink for better heat dissipation. Power Source Phase: Single-phase color: White Material: plastic and metal Rated Voltage: single-phase/3-phase AC220V Power Supply Voltage: Low voltage Suitable Motor Power: 2.2kW Filter: Built-in filter DC Power Supply Type: Voltage type Control : V/F closed loop Output Voltage Adjusting : PWM control Rated Current: 12A Protection: Over-current, over-voltage, over-heat, under-voltage, short circuit protection Max.
