Description :
This VFD 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 inpute for this VFD is 1 or 3 phase as you like. You can control the different speed as you like when yo use this VFD.
You can use for : Lathes, Mills, Car Hoists, Pumps & Conveyors, etc and then performance excellently. This item use Sine wave PWN(SPWM ) for the control system and performace excellently.
Features :
1) PID control; advanced calculus PID closed-loop arithmetic, quick responding speed and high suitability;
2) Easy PLC function can realize 16 legs of speed and inverter control function;
3) RS485 communication port, adopting standard international MODBUS main circuit control;
4) With extremely strong anti-jamming capability;
5) Low output ratting torque0.5HZ-150%, low speed running ability;
6) Carrier adjustable by 16KHZ, completely soundless working environment;
7) Broad voltage working area, normal running in 304V-456V;
8) Auto voltage regulation (AVR) technique, for ensuring the inverter load capability;
9) Various control technique by both synchronization and non-synchronization, dynamically realize fast starting without changing brakes;
10) With perfect error protection and short circuit starting protection capability;
Tech parameters :
1) Input Voltage : 220V(+/-15%) / 380V(+/-15%).
2) Output Voltage : 220VAC or 380VAC
