Description of Regenerative drive:
This series adopts microprocessor chip with fast respond, high-accuracy process control, which is safe, stable and reliable for operating. It can make the inverter operating in four-quadrant, continuously feedback,and regenerative braking frequency below 40%. Electric regeneration efficiency up to 97%. Using SPWM modulation to greatly reduce distinctive peaks of current and form perfect sine wave current, input side current THD lower than 5%, power factor up to 99%.It can prevent power grid flowing back, overheating, overcurrent, out of phase, undervoltage,and short circuit.
