<b>Introduction</b> <br> <br> <br> This VFD can be used for constant torque loads(such as hard starting:Air conpressor,HVAC units) and variable torque loads(such as pumps,fans,etc) It can be used as a motor speed control and a phase converter.The inpute for this VFD is single phase. You can control different speed when you use this VFD.Most of our customers bought this VFD from us to use for:Lathes,Mill,car Hoists,Pumps&conveyors,etc.This item use sine wave PWN(SPWM) for the control system and performace excellently. <br> <br> <br> <b>Technical Parameters</b> <br> <br>Input voltage:220V±15%(we also stock 110V and 380V+/-15%,please contact us for item stock) <br> Input Frequency: 48 to 63 Hz <br> Output Frequency: 0 to 400 Hz <br> Input Phase:single phase <br> Output Phase: 3 phase <br> <br> <br> <b>Features</b> <br> <br> 1.Our item adopts the Japan Mitsubish chip; <br> 2.PID control; advanced calculous PID closed-loop arithmetic, quick responding speed and high suitability; <br> 3.Easy PLC function can realize 16 legs of speed and inverter control function; <br> 4.RS485 communication port, adopting standard international MODBUS main circuit control; <br> 5.With extremely strong anti-jamming capability; <br> 6.Low output ratting torque, low speed running ability; <br> 7.Carrier adjustable by 16KHZ, completely soundless working environment; <br> 8.Broad voltage working area; <br> 9.Auto voltage regulation (AVR) technique, for ensuring the inverter load capability; <br> 10.Various control technique by both synchronization and non-synchronization, dynamically realize fast starting without changing brakes
