Features:ThisVFD uses unique control method to realize high moment of force, high accuracy and wide speed regulating range driving, with high performance. Ithas good anti-trip performance and ability to adapt to rough power, temperature, humidity and dust interference, greatly improved stability. Byoptimizing PWM control technology and electromagnetic compatibility, itsatisfies 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.Specifications: Model: AT1-2200X Power Source Phase: Single-phase Rated Voltage: single-phase or 3-phase AC220V Power Supply Voltage: Low voltage Suitable Motor Power: 2.2kW Filter: Built-in filter DC Power Supply Type: Voltage typeControl Method: V or F closed loopOutput Voltage Adjusting Method: PWM control Rated Current: 12A Protection: Over-current, over-voltage, over-heat, under-voltage, short circuit protection Max.
