Variable Frequency Drive Inverter VFD NEW
7.6HP 5.5KW 220V-250V
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.
