Features:  -Quick heat dissipation and longer service life.  -0.1s～3600min can be set continuously, S-type and linear mode are optional.  -LK710 series inverter is a high-performance vector heavy-duty inverter.  -Strong anti-interference ability, large low-frequency torque, high precision.  -Overcurrent, overvoltage, undervoltage, module failure, electronic thermal relay, overheating, short circuit, input and output phase loss, abnormal motor parameter tuning, internal memory failure, etc.  -According to the needs, you can choose dynamic voltage regulation, static voltage regulation, and unregulated regulation to obtain the most stable operation effect.  -Upper and lower limit frequency setting, frequency jump operation, reverse operation limit, slip frequency compensation, RS485 communication, frequency increase and decrease control, fault self-recovery operation, etc.     Specifications:  Name: Variable Frequency Inverter.  Color: black.  Input: 3PH AC 380V 50-60Hz.  Output: 3PH 0-500Hz.  Power: 0.75KW/1.5KW/2.2KW.  Current: 2.1A/3.8A/5.1A.  Control Method: voltage vector.  Size: 151 x 100 x 133mm/6 x 4 x 5in.     Safety Precaution:  1. Before wring, please make sure that the input power is off.  2. The wring work should be operated by the professional electrical engineer.  3. The grounding terminals must be connected with the ground.  4. Having paused circuit wiring emergently, please make sure that the check is effective.  5. Do not connect the output wire of the inverter with the shell, and pay attention that the output wire should not be short-circuited.  6. Please check whether the voltage of the AC main circuit power is consistent with the rated voltage of the inverter.  7. Do not do the voltage withstand test on the inverter.  8. Please connect the brake resistor according to the wiring diagram.  9. Do not connect the power to the V, U, W output terminals.  10. Do not connect the contactor with the output circuit.  11. Mare sure to install a protection cover before power-on. When removing the cover, be sure to make the power off.  12. If you want to reset the inverter with the retry function, do not get close to the mechanical equipment, because the inverter will restart suddenly when the alarm stops.  13. Confirm that the operation signal is cut off. Before reset the alarm device,or the inverter may start suddenly.  14. Do not touch the terminals of inverter, which are very dangerous because there is high voltage on them.  15. When power is on, do not change the wiring and terminal.  16. Cut off the main circuit power before doing some check and maintain work.  17. Do not arbitrarily reform the inverter.     Package Included:  1 x Variable Frequency Inverter
