Description

Elevator Energy saving device can send the energy fromcapacitance to area AC network and serve for other electric equipment, saving electric obviously, power saving can reach maximally *5%. In addition, since no resistant of heating element, the temperature of machine room is lower, we can save the consumption of air-condition, in many occasions, saving consumptions of air-condition can bring sound effect.

PRODUCTS FEATURES

*We adopt PWM technology to output correct phase, and restrain higher harmonic effectively.

*We adopt DSP CPU, which has high speed, precision, stability and anti-jamming ability.

*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.

*Voltage distortion:＜5%, fit the harmonic requirements of IEC********2 and GB/T****9.

*It can be used in network connection with **0VAC~**0VAC or **0VAC~**0VAC directly through a reactor or filter. Electricity saving will be obvious in frequent braking situation.

*Energy conversion rate can reach above *7%.

*Empty load up can save *5% and Full load down can save *5%.

*Indicate the numbers of pitch point according real time.

*Twin channel protect installed internally.

*Building block design, support power extending.

*Support data teletransmission.

ADVANTAGES

*It realized the four quadrant operation of frequency converter system.

*Braking energy was recycled, increase the efficiency of system greatly. educe The facilities for reduce temperatures in elevator machine room can be closed.

*The heat productivity of system is reduced , and improved the safety and comfortableness, also decrease the amount of work.

*Improving brake effect, adapt the requirements of prompt and frequent braking action.
