Features:

  • Inverter Power Supply Board
  • Integrated trigger circuit support
  • Electrical isolation architecture
The Allen-Bradley PN-173122 / PN-200959 Inverter Power Supply Board is a dedicated auxiliary power supply and trigger board designed specifically for the PowerFlex 700 series of Allen-Bradley AC variable frequency drives (VFDs). This board serves as the critical power conversion and distribution hub within the drive system, converting incoming 3-phase AC power (380–480 V, 50/60 Hz) into stable, isolated DC voltages required for the drive's internal control electronics, gate drivers, and peripheral sensors.

The board provides a main 24 V DC output to power the drive's control circuits, along with auxiliary 15 V DC and ±12 V DC outputs for analog sensors, logic circuits, and communication modules. With a total power capacity of up to 150 W, it ensures reliable operation across a wide range of PowerFlex 700 standard-duty drive models, typically covering motor power ranges from 15 kW to 110 kW depending on the specific drive configuration.

The PN-173122 / PN-200959 Allen-Bradley Inverter Power Supply Board may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).
Allen-Bradley PN-173122 / PN-200959 Manuals, Datasheets, Drivers, Link Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
Comprehensive protection features are integrated directly on the board, including input overvoltage/undervoltage protection, output overcurrent limiting, short-circuit protection, and overtemperature shutdown. The board also includes a Power-OK relay output and alarm signal pins that provide real-time status feedback to the main control board, enabling proactive fault detection and system diagnostics. Status indication is provided via onboard LEDs for Power, OK, and Fault conditions.
Built for industrial environments, the board utilizes a high-quality FR-4 PCB with high-temperature coating and a 94V-0 flame-retardant rating. It operates reliably in temperatures from -10°C to +60°C and can be stored in conditions ranging from -40°C to +85°C. The IP20 protection class makes it suitable for installation within sealed electrical cabinets.

This content has been produced using multiple sources.Amikon takes no responsibility for the accuracy of this information. Always consult the original equipment manufacturer for the most up to date instructions and information.
Disconnect Power: Remove and lock out all incoming AC and DC power sources to the drive. Follow your plant's standard Lockout/Tagout (LOTO) procedures.
Wait for Discharge: Wait a minimum of 15 minutes (or the exact time listed on the drive's warning label) to let the internal DC bus capacitors discharge safely.
Verify Zero Voltage: Use a reliable digital multimeter to measure the DC bus voltage across the +DC and -DC terminals or test point sockets. The voltage must read zero before touching any internal boards.

Technical notes

The board incorporates power conditioning components, capacitor banks, trigger circuitry, isolation sections, and protection circuits that help maintain reliable inverter operation. It is installed within the drive chassis and works together with rectifier, trigger, and inverter modules to support controlled motor acceleration, speed regulation, and power conversion functions. Some industry references also identify the PN-173122 and PN-200959 assemblies as inverter power supply, trigger, or inverter control boards used within medium- and high-power drive systems.

FAQs

  • What are these parts used for?

    +
    They serve as the trigger and auxiliary power boards that supply electricity to the drives' control sections and rectify signals
  • What do these part numbers represent?

    +
    The component is commonly listed with both numbers together because PN-200959 designates the overall drive/trigger board assembly, while PN-173122 is the specific printed circuit board (PCB) fabric identification layer printed on the physical board.
  • Which industrial equipment uses this board?

    +
    It is engineered for heavy-duty industrial automation, primarily serving as the trigger power board inside Allen-Bradley PowerFlex 753 and PowerFlex 755 frequency inverters
  • What is its core function?

    +
    It manages gating signals and gate driver power distributions required to safely switch the triac or SCR blocks within the drive's front-end rectifier and power inverter circuit.
