Features:

  • Bridges the three-phase AC industrial power source to the PowerFlex 700 drive internal control circuits
  • Integrates AC-to-DC power conversion with multi-channel isolated DC output support
  • Functions in coordination with the main control board and thyristor power modules within the PowerFlex 700 drive system
The Allen-Bradley PN-173123 Power Supply Board serves as the dedicated auxiliary power supply within the PowerFlex 700 drive enclosure, providing reliable isolated DC power to all control and logic modules throughout the system.Comprehensive protection circuitry is built into the PN-173123, including input overvoltage/undervoltage detection, output overcurrent limiting, short-circuit safeguarding, and overtemperature shutdown.

The PN-173123 provides essential power functions common to the entire drive, and is a critical component of the motor control path, directly affecting the proper, normal operation of the overall variable frequency drive system. One PN-173123 power supply board is required per drive unit depending on the power rating and chassis size. The PN-173123 mounts within the drive enclosure and occupies a designated board slot adjacent to the main control board and power module assembly, secured via standard mounting hardware and connected through ribbon or edge-card interfaces.

For standard single-supply operation, the PowerFlex 700 system continually monitors the health of the PN-173123 through the main control board. If the system detects that the PN-173123 is no longer providing stable output (outside configured voltage and tolerance levels), it will trigger a drive fault status and place an event in the system fault log, alerting maintenance personnel to inspect or replace the board.

The PN-173123 Allen-Bradley Power Supply Board may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
What is the Allen-Bradley PN-173123 board designed for?
The Allen-Bradley PN-173123 is designed to act as a resilient voltage conversion and regulation layer inside industrial variable frequency drives. It isolates sensitive gate driver circuits from incoming power anomalies, helping stabilize internal electronics and prevent failures caused by voltage fluctuations and electrical noise.
How does the Allen-Bradley PN-173123 improve VFD system stability?
It improves stability by filtering and regulating unstable incoming power caused by heavy industrial switching loads. By maintaining consistent voltage delivery, it reduces harmonic stress, stabilizes gate-firing behavior, and helps prevent unexpected shutdowns or control board malfunctions in high-demand drive operations.
How is the Allen-Bradley PN-173123 installed in a drive system?
It is installed directly inside the drive chassis and secured using manufacturer-specific mounting brackets to ensure correct positioning for cooling and electrical isolation. During installation, all connectors must be firmly seated, and safety procedures such as full lockout-tagout (LOTO) and capacitor discharge must be completed before handling the drive.
