Performance characteristics of energy feedback device

& yen; Voltage and power range: 220v-380v;; ; 7.5-300 kilowatts.

& yen; Substitution: using braking unit+resistance = energy feedback braking, completely replacing.

& yen; Energy saving: the efficiency is as high as 97%, which improves the economic benefit of operation, saves energy and protects the environment.

& yen; Safety: advanced power electronics technology and high-performance IGBT are used as switching devices;

Using PWM pulse width modulation technology, the output phase is accurate and the higher harmonics are effectively suppressed;

Adopting DSP CPU has the advantages of high speed, high precision, good stability and strong anti-interference ability.

Voltage distortion rate

Improve the braking effect and meet the engineering requirements of rapid braking and frequent braking.

& yen; Feedback: Self-diagnosis technology is adopted to ensure accurate output voltage, prevent current from flowing back, and make the frequency converter unaffected.

& yen; Practicality: The system has good power saving effect, low calorific value, high safety and small maintenance workload.

& yen; Can be used in parallel, and can be applied to occasions with higher power.

Advanced IGBT devices and phase-amplitude control PWM algorithm are used to improve the deceleration braking ability of the inverter, and at the same time, the energy generated by the motor during braking and input into the inverter is fed back to the power grid, which can meet the effective braking of the inverter and recover more than 95% of the regenerative electric energy.
