ALLEN BRADLEY SK-H1-SVFB2-E1 39516 PowerFlex 700S Voltage Feedback Kit

Overview

The ALLEN BRADLEY SK-H1-SVFB2-E1 39516 is a voltage feedback kit designed for Allen‑Bradley PowerFlex 700S series AC drives, frame size 9 to 14, 600/690V class. The ALLEN BRADLEY SK-H1-SVFB2-E1 39516 collects real-time voltage sampling signals inside the inverter and transmits feedback data to the main control board for closed-loop regulation. It is an original spare assembly for the PowerFlex 700S high-performance drive system. The ALLEN BRADLEY SK-H1-SVFB2-E1 39516 has been discontinued by Rockwell Automation and is mainly supplied for on-site maintenance and replacement of legacy drive units.

Features

The ALLEN BRADLEY SK-H1-SVFB2-E1 39516 provides accurate voltage sampling and feedback for 600/690V PowerFlex 700S drives. It supports stable closed-loop voltage control to guarantee drive output waveform quality. The ALLEN BRADLEY SK-H1-SVFB2-E1 39516 matches the original frame 9‑14 hardware structure and wiring definition for direct plug-in replacement. It adopts industrial PCB design with stable performance under high voltage cabinet environment. The ALLEN BRADLEY SK-H1-SVFB2-E1 39516 is an obsolete spare part with no official replacement solution.

Specs

Device Type: Voltage feedback kit Model: ALLEN BRADLEY SK-H1-SVFB2-E1 39516Compatible Drive: PowerFlex 700S AC drive Frame Range: Frame 9 to Frame 14 Voltage Class: 600/690V Function: Internal voltage sampling and feedback signal transmission Status: Discontinued by manufacturer Installation: Internal assembly inside PowerFlex 700S inverter cabinet

Principle

The ALLEN BRADLEY SK-H1-SVFB2-E1 39516 samples DC bus and output voltage signals from the power stage. The circuit converts high-voltage signals into low-voltage feedback signals that the main control board can process. The control board adjusts the IGBT switching strategy based on the feedback data to stabilize output voltage. When abnormal voltage is detected, the ALLEN BRADLEY SK-H1-SVFB2-E1 39516 helps the drive trigger protection and fault alarm.

Applications

The ALLEN BRADLEY SK-H1-SVFB2-E1 39516 is used for spare replacement of PowerFlex 700S 600/690V drives in industrial production lines. It supports maintenance of heavy-duty conveyor, extruder and large fan drive systems. The ALLEN BRADLEY SK-H1-SVFB2-E1 39516 applies to emergency repair and spare stock for legacy Rockwell automation systems. It serves voltage feedback loop restoration for high-power variable frequency drive equipment.
