Frequency converter selection<br> For light loads, choose one grade larger (1.5kw motor chooses 2.2kw) and 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<br> Power: 2.2KW<br> Input voltage: 220V(170V-240V) Single phase/380V(330V-440V) Three phase<br> Output voltage: 380V(330V-440V) Three phase<br> Frequency range: 0.1-400Hz<br> Output frequency accuracy: 0.1Hz<br> Control mode: space vector, V/F control<br> V/F control: V/F curve can be set arbitrarily to meet the needs of different loads.<br> PID controller: built-in PID controller<br> RS485: standard RS485 (MODBUS) communication function<br> Protective function<br> Overload protection: constant torque 150%/1 min, variable torque 120%/1 min.<br> Overvoltage protection: Overvoltage protection can be configured.<br> Undervoltage protection: protection can be set<br> Other protections: short circuit protection, over current protection, parameter lock, etc.<br> Colour:Black<br> Material:Plastic + Metal<br> Package Contents:<br> 1x Universal Frequency converter<br> Only the above package content, other products are not included.<br> Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
