220V TO 380V Economical VFD Variable Frequency Drive Converter Inverter 1.5/2.2/3.7/4/5.5/11/22KW Motor Speed Controller

Description Product Introduction Frequency converter selection(TOHE200) For light loads, choose one grade larger (1.5kw motor chooses 2.2kw) and heavy load selection multiplies by 2 (2.2kw motor chooses 5.5kw). Because the voltage needs to be changed, the pressure on the inverter is relatively high, so choose to leave enough margin Function advantages: 1. Forward, reverse, start and stop controlled by panel or external terminals. 2. Adjust speed by panel potentiometer or external potentiometer. 3. Built-in brake unit (for connecting brake resistance). 4. PID function (Constant pressure water supply). 5. Multi-stage run. 6. RS485 communication protocol by PLC. 7. Vector control, low frequency high torque. 8. Optional external control panel(not included in the package). 9. Overload protection.
