Product Profile
Elevator energy feedback feeds back the regenerative energy generated during the process of motor speed regulation to the
power grid, avoiding the energy loss caused by conventional energy consuming braking units due to resistance heating, thus
achieving considerable energy-saving effects.
In the application of elevators, direct current energy is converted into direct current energy through electric motors and
frequency converters, and there is a heating resistor that consumes it. Usually, the excess mechanical energy (including potential
energy and kinetic energy) during the light load up and heavy load down of the elevator can be effectively converted into direct
current electricity by using the elevator energy feedback device for energy conservation. The direct current energy consumed on the
original resistance side can be returned to the local ACpower grid for use by other surrounding electrical equipment, with a power
saving rate of up to 15-40%; At the same time, there is no resistance heating element, which reduces the temperature of the
computer room, greatly saving the power consumption of the air conditioning and cooling equipment in the computer room.
Product Features
The stored DC energy is effectively converted into AC energy and sent back to the power grid. The energy generated by braking is recycled and the system efficiency is improved.;
Real time feedback of accumulated electricity metering, with a power saving rate of 15%~45%;
No resistance heating element, reduce the use of air conditioning and exhaust facilities, and reduce the ambient temperature of the machine room;
Do not change the original control mode of the elevator,and the original system is redundant,the system runs more safe and reliable;
Expandable function port for dynamic reactive power compensation SVG, improving the active power factor of the motor, high efficiency, and one click switching between feedback and compensation;
Equipped with motor compensation function, low harmonic and no interference
Applications
Elevator energy feedback is suitable for various brands of vertical elevators and mainstream traction machine brands both
domestically and internationally.

Energy saving testing methods
When testing, connect the meter according to the diagram, the meter should use the "reverse connection and reverse counting"
induction meter, concentrate on more than 2 hours, control the elevator empty box up and down, and cycle until the total power
consumption is more than 3 degrees.
During the test, pay attention to checking that one of the meters will have a reverse dial and a decrease in reading when going
up, and a positive dial when going down. Otherwise, check if the selected meter is suitable. (The measurement of the energy-saving
meter is based on the measurement of the feedback unit)
