PowerFlex Common Bus

PowerFlex 700AFE Active Front End

The PowerFlex 700AFE Active Front End is a regenerative DC bus supply used to supply DC power to a line-up of AC drives with common DC bus input or a single common bus drive. The AFE allows regeneration to the AC power line and provides low harmonics to meet IEEE-519 requirements. 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.

Features

• 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.
• 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.
• 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.
• Premier Integration with PowerFlex Drives and RSLogix 5000. For simplified AC drive start-up and reduced development time, we’ve integrated the PowerFlex 700AFE configuration with RSLogix™ 5000 software. This single-software approach simplifies parameter and tag programming while still allowing stand-alone drive software tool use on the factory floor.
• Common Communication and Human Interface Options. The AFE utilizes the same Communication Modules and Human Interface Modules as Allen-Bradley’s Architecture class PowerFlex drives.
