Introduction This VFD can be used for constant torque loads (such as hard starting: Air compressors, HVAC units) and variable torque loads (such as pumps, fans, etc). The inpute for this VFD is 1 or 3 phase as you like. Many customer bought this VFD from us to use for: Lathes, Mills, Car Hoists, Pumps and Conveyors, etc and then performance excellently. This item use Sine wave PWN(SPWM) for the control system and performace excellently. Technical Parameters Input Voltage: 220±15% (We also stock 380±15%, please contact us for item stock) Output Voltage: 208 to 240VAC (analogous to Input Voltage) Input Frequency: 48 to 63 Hz Output Frequency: 0 to 400 Hz Input Phase: 1 or 3 phase as you like Output Phase: 3 phase Features 1.Our item adopts the Japan Mitsubish chip; 2.PID control; advanced calculous PID closed-loop arithmetic, quick responding speed and high suitability; 3.Easy PLC function can realize 16 legs of speed and inverter control function; 4.RS485 communication port, adopting standard international MODBUS main circuit control; 5.With extremely strong anti-jamming capability; 6.Low output ratting torque, low speed running ability; 7.Carrier adjustable by 16KHZ, completely soundless working environment; 8.Broad voltage working area; 9.Auto voltage regulation (AVR) technique, for ensuring the inverter load capability; 10.Various control technique by both synchronization and non-synchronization, dynamically realize fast starting without changing brakes
