Elevator Energy Saving Devices

タイトルまたは説明

.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:¼œ5%, 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.
