Note: For soft cable with single section more than 10mm2, we suggest you choose symmetrical structure. Symmetrical structure inverter cable has low and uniform impedance thus can avoid interference of high order harmonic to nearby controller cable caused by frequency change of large power electricity transmission.
- Energy Regenerator
1. Our energy regenerator adopts high speed DSP chips to monitor the power grid voltage. Thus this product is of high efficiency and has small feedback impact on the power grid. It is a product conforming to the national and industrial standards. 2. Phase amplitude control algorithm and PWM technology are employed in this energy regeneration device. 3. IGBT high-speed switch components ensure less switch loss and high operation efficiency. 4. The current fed back to the power grid comes with sine waveform and the current total harmonic distortion is less than 5%.
- Elevator Inverter
AS320 elevator inverter is a kind of newly developed frequency inverter especially for elevators. It is designed with 32-bit MPU for motor driving, high performance complex programmable logic device (CPLD), and advanced power module. Meanwhile, the elevator inverter is designed based on international advanced closed loop vector control technology and supports various control modes including V/F control, sensorless vector control, and torque control modes. Integrating the characteristics of potential energy load, the elevator inverter allows elevators to operate efficiently, smoothly and steadily, and offers passengers a comfortable feeling.
