2.2kw VFD (240v or 3 phase input) Kit
These awesome digital VFDs can be used for constant torque loads ( such as hard starting: Air compressors, 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 input for this VFD supports either a 240V single phase or 3 phase input.
They support full range speed adjustment from ~100rpm to 24,000rpm and are designed to control 3 phase motors on Lathes, Mills, Car Hoists, Pumps & Conveyors, grinders, the options are endless.
These VFDs support either an external potentiometer for speed control or PWM speed control from a microcontroller. You can also adjust the speed using the + or - buttons on the front of the LCD panel.
The efficient design of these VFDs with built-in heatsink and cooling fan allows the unit to run continuously for hours of use at full load.
