Regenerative drive for elevator 150A,55KW, Chopper Voltage310V
Description of Regenerative Unit:
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 .
