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 45%. 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 IEC61000-3-2 and GB/T14549.
*It can be used in network connection with 300VAC~460VAC or 150VAC~230VAC directly through a reactor or filter. Electricity saving will be obvious in frequent braking situation.
*Energy conversion rate can reach above 97%.
*Empty load up can save 35% and Full load down can save 45%.
*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.
PARAMETER INDEX :
Power range: 0~30kw
