WNK intelligent electric energy saving recycle device

WNK intelligent electric energy saving recycle device
Product Detailed
WNK intelligent electric energy saving recycle device change moving load into electric power elevator,lifter ,centrifuge

WNK intelligent electric energy saving recycle device 


suitable for static energy load, large inertia load, frequently accelerate and brake for long time place

energy saving reform for elevator and affiliated with equipment

energy saving  for cranes( small power), lifter and affiliated with equipmenet

affiliated with various lifters used in vertical well, oblique well, single channel, double channel of mines and energy-saving reform.

affiliated with various cranes and ports lifters and energy saving reform

energy recycle and saving with high reliablity for other centrifuges used in factory

other sites need continually producint electricity and feedback power network


the mechanical energy from moving load can be changed into electricity power by energy feedback equipment, then return to AC power network  which can supply the electricity for other equipment.

It can make motor dragging system reduce the loss of electricity energy in unit time for the purpse of saving electricity power

substitute: break unit+resistance = energy feedback WNK

energy saving: feedback regeneration energy to power network, efficiency can reach to 97, increase economic benefits and protect environment

Safety: adopting advanced electronic technologh and high-power IGBt AS SWITCH ACCESSORY

  adopting PWM pulse width modulation technology, the output phase is accurated  and it can prepress high order harmonic wave

adopting DSP CPU with high speed, high precision ,goods reliablility, strong anti-jamming ability

voltage aberrance rate<5%, accordance with IE61000-3-2 and GB/T 14549 for power network harmonic wave

recycle: adopting self-diagnosis technology to assure the accuracy of output voltage ,prevent electricity returning and make the transducers work without any influence.

Practicability: goods effect of system power saving, low heating, high safety and less maintenance

Able to use parallel ocnnection applied in the large power places.

over heat protection:L 70C

feedback efficiency: above97%

working records: DC generatrix voltage, DC generatrix current, AC sidetrack voltage, feedback current, modulation ration, and control angle, record data within the latest 3.5 minutes


state display: three states--waiting, working and malfunction

operating monitor: display 4 different states: DC voltage, DC current, AC voltage and feedback current

Malfunction display: display malfunction code and automatically record the codes in EROM for 2.5s before maulfunction


installation place: indoors, the altitude does not exceed 1000m, no sunshine, no dust conducting electricity and no corrosible gas

vibration degree: below 0.5kg

MEMO: our company has different types for elevators, centrifuges, mine lifters and us for detail.
