The PowerFlex 700AFE Active Front End is a great fit for applications that require regeneration of power back to the utility and/or low harmonics to meet IEEE-519 and CE standards. The PowerFlex 700AFE is a regenerative DC bus supply used to supply DC power to a line-up of common bus AC drives or a single common bus drive. The AFE utilizes a pulse width modulated (PWM) controlled IGBT converter to allow bi-directional power flow to the AC line.
Advantages
Regenerative Braking for Energy Savings and Elimination of Braking Resistors
- The AFE eliminates the need for large resistor banks. These resistors banks can create a lot of heat and must frequently be cleaned. Instead of wasting energy with resistor braking technology, regenerative braking actually puts the energy back into the system to be used by other equipment.
- Low AC Input Harmonics
The active front end provides low harmonics to meet IEEE 519 and CE at its input terminals.
- Voltage Boost
The AFE allows "input voltage boost" operation, providing full 480 VAC to the motor, even when operating on 380 VAC power lines. This voltage boost also helps protect critical processes from the potentially disruptive effects of input voltage dips and sags.
- Improved Power Factor
The AFE itself actively controls the power factor regardless of motor speed and load. In addition, the PowerFlex 700AFE can be used for power factor correction on the power system.
