Regenerative drive for elevator 75A,37KW, Chopper Voltage 620V

This series adopts 32 bit high-performance industrial MPU with fast respond, high-accuracy process control， making 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.

Sikes regenerative unit can replace the conventional braking unit & resistors , which collect the power usually wasted into heat and convert it back into power grid . The advantages are obvious :
1: Collect the extra power generated by VFD instead of wasting it as heat , so cool down the equipment and extend service life .
2: By reducing the temperature of the equipment , it also reduce the load of cooling equipment , another saving on power cost .
