220V 1.5KW \/ 220V 2.2KW \/ 380V 1.5KW \/ 380V 2.2KW for Option  Description : <br>  <br> 220V\/380V 1.5KW\/2.2KW Variable Frequency Drive VFD Inverter  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 &amp;amp; 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 3) Input Frequency : 48 - 63 Hz 4) Output Frequency : 0 - 650 Hz 5) Input Phase : 1 or 3 phase (1 phase for 220V， and 3 phase for 380V)<br> 6) Output Phase : 1 or 3 phase (1 or 3 phase for 220V， and 3 phase for 380V)   Specification :  <br>               Inverter Series         WK-9000               Control Mode         SPWM               Input Power         330~440Vfor 380V power; 170~240V for 220V power               4Digits Display &amp;amp; Status Indicator Lamp         Displaying frequency， current， revolution， voltage， counter， temperature，      forward or reserve running， and fault， etc.               Communication Control         RS-485               Operation Temperature         -10~40\u2103               Humidity         0-95% Relative Humidity(without dew)               Vibration         Below 0.5G                                                               Protection Functions                                                   Overload Protection         Electronic relay protection motor      Drive(for constant torque  150%\/1 min. for the kinds of fan 120%\/1min.)
