As for material, labor, transportation cost and exchange rate are changing,  the price for this is just for reference only, please contact us before hand if you are interested.





○ National key product in new plan Reported by CCTV repeatedly
○ ¥20 million guarantee by Min an insurance
○ Integrate Save electricity 30%
○ Used in the ministry of science and technology, the general hospital of China PLA
and other more than 1000 energy saving program in countrywide







If we can apply the energy saving device to every elevator, we will save 11.4billion
kWhs energy, just like saving 3,800,000 ton standard coal, reduce 9,950,000 ton

carbon dioxide, 32000 ton sulfur dioxide and 28,000 ton nitric oxide gas waste.


1.We adopt PWM technology to output correct phase, and restrain higher harmonic
2.We adopt DSP CPU, which has high speed, precision, stability and anti-jamming
3.We adopt self-diagnostic techniques to ensure the accurate of output voltage, and
in case of current post back, to make the frequency convertor out of influence.
4.Voltage distortion: <5%, fit the harmonic requirements of IEC61000-3-2 and GB
5.It can be used in network connection with AC150~460Vdirectly through a reactor or

filter. Electricity saving will be obvious in frequent braking situation.
6.Energy conversion rate can reach above 97%.
7.Empty load up can save 35% and Full load down can save 45%.
8.Indicate the numbers of pitch point according real time.
9.Twin channel protect installed internally.
10.Building block design, support power extending.
11.Support data teletransmission.



① It realized the four quadrant operation of frequency converter system.
② Braking energy was recycled, increase the efficiency of system greatly. The

facilities for reduce temperatures in elevator machine room can be closed.
③ The heat productivity of system is reduced , and improved the safety and comfor-

tableness, also decrease the amount of work.
④ Improving brake effect, adapt the requirements of prompt and frequent braking
