Feature:1. FREQUENCY INVERTER: This VFD allows for driving with large torsion, high accuracy, quick response as well as wide adjustable speed range.2. UNIQUE PWM CONTROL: Optimized PWM control and electromagnetic compatibility ensure low noise and low electromagnetic interference.3. STABLE WORKING: Has good anti trip performance and the ability to adapt to coarse power, temperature, humidity and dust interference.4. PRACTICAL USING: Can be widely applied on motor, mixer, ball mill, water pump, cranes, conveyor, air compressor, fan, CNC machine tool, etc.5. CONVENIENT WIRING: After removing the screw, connect it directly to the wire, the simple wiring also makes the installation more convenient.Specification:Item Type: Variable Frequency DriveParameterPower (KW)Input Voltage (V)Output Voltage (V)Frequency Range(Hz)AT1-1500S1.51 Phase 2203 Phases 0-2200-400AT1-2200S2.21 Phase 2203 Phases 0-2200-400Shell Material: ABS PlasticPower Phase Number: 1 phase.
