Energy regeneration Active Front End

Product Features 1.Adopting microprocessor chip with fast respond, high-accuracy process control, safe, stable and reliable for operating. It can make the inverter operating in four-quadrant, continuously feedback, regenerative braking frequency is 100%. Electric regeneration efficiency up to 97%. 2.

Strong anti-jamming ability: It uses SPWM modulation to greatly reduce distinctive peaks of current and form perfect sine wave current, input side current THD lower than 5%, power factor up to 99% 3. Excellent Protection: It can prevent power grid flow back, overheat, overcurrent, out of phase, undervoltage, short circuit. 4.

Adaptive connection mode, no need to identify Plus-n-Minus when connect to Inverter or power grid, very easy to connect. 5. Intelligent digital keypad for easy operation, can modify operation voltage, online monitoring input voltage, DC bus voltage, output current and temperature of the radiator.

It can store relevant operating data and fault ourputs for trace and diagnose. Additional RS485 or Ethernet interface is avaliable for data transfer and long distance operation. 6. It contains built-in intelligent fan, high and low order harmonic filter, external short circuit protection. 7. Suitable for all inverters.

Similar to Siemens, ABB, Schneider, Fuji and Yaskawa Active Front End. 8. Warranty period:18 months.
