Inpute phase: 1 phase. Outpute phase:3 phase. 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 1 or 3 phase as you like. 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. Easy PLC function can realize 16 legs of speed and inverter control function. RS485 communication port, adopting standard international MODBUS main circuit control. With extremely strong anti-jamming capability. Low output ratting torque 0.5HZ-150%, low speed running ability. Carrier adjustable by 16KHZ, completely soundless working environment. Broad voltage working area. Auto voltage regulation (AVR) technique, for ensuring the inverter load capability. Various control technique by both synchronization and non-synchronization, dynamically realize fast starting without changing brakes. With perfect error protection and short circuit starting protection capability. 9001 Quality certification, which means this item is of the top quality item. 220V class:220V(+/-15%). 5-Digits Display & Status Indicator Lamp.
