Feature
1. Multiple elevator regenerative power unit can be connected in parallel to use together.
2. The power unit adopts 32 bit high performance microprocessor chip with quick response and high-precision control to achieve safe, stable and reliable operation.
3. SPWM modulation is applied to enhance power factor, optimize output wave current and achieve lower distortion rate.
4. The device features intelligent detection and control, which supervises current, voltage and temperature under acceleration, deceleration or steady state operation of the motors.
5. The product is equipped with protection functions to prevent power grid flowing back, overheating, overcurrent, out of phase, undervoltage and short circuit.
6. The power unit adopts self-adaptive wiring techniques, freeing the need to disassemble the discharging resistor, to distinguish the positive and negative poles of the bus, or to distinguish the three phases when connecting to power grids.
7. An operational panel with changeable action potential is integrated with the device; all execution parameters can be modified using press keys. The panel shows input DC voltage, output AC voltage, output AC current and module temperature, with an interior memory unit recording the input voltage, output voltage/current and module temperature at last fault.
8. The device embeds within itself an intelligent cooling fan and a low frequency wave filtering device.
9. The power unit is compatible with all domestic and imported elevators.
