Elevator Energy Saving Device

1.We adopt PWM technology to output correct phase, and restrain higher harmonic
effectively.
2.We adopt DSP CPU, which has high speed, precision, stability and anti-jamming
ability.
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
/T14549.
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.
