Active Components

Product Description
Traditional braking resistors are replaced by Active Front End (AFE) to reduce heat energy!AFE does not dissipate excessive heat into air but converts it into reusable power that can be back to the mains.AFE is a controllable rectifier with advantages such as providing bidirectional power exchange between AC and DC power and regenerating reusable power to the mains to reduce the cost of power.
Product Feature
1.Replace traditional braking resistors with energy generation
2.Provides bidirectional power exchange between AC and DC power
3.Regenerating reusable power to the mains to reduce the cost of power
4.Uses PWM modulation to greatly reduce distinctive peaks of current
5.Eliminates high order harmonics
6.Offers stable power quality that is unaffected from mains power fluctuations.
7.Clear energy savings with more than 95% of regenerative energy converted and supplied back to the mains.
Product Specification/Models
1.Adopting DSP CPU with fast respond, high control accuracy, safe, stable and reliable for operating, strong anti-jamming ability. It can make the inverter operate in four-quadrant, feedback discontinuity, regenerative braking frequency is 40%. Recycle efficiency up to 97%.
2.Adopting SPWM pulse width modulation technology, the output phase is accurated and it can prepress high order harmonic wave.
3. Protection: can prevent power grid flow back, overheat, overcurrent, out of phase, out of voltage, short circuit. Thermal loss is lower than 3% of energy consumption braking.
4. Adaptive connection mode, easy to use.
5. Intelligent digital control pannel for easy operation.
6. Inbuilt intelligent fan, low frenquency filter, external short protection. Can store relevant data for trace and diagnose.
7. Suitable for all inverters, such as Siemens, ABB, etc.
