ABB FPX86-9345–B 3BHL000986P0006

Description

Product Description

The ABB FPX86-9345–B 3BHL000986P0006 is a sophisticated Power Supply Module designed for ABB’s flagship ACS 6000 series of medium-voltage drives. This specific component, the ABB FPX86-9345–B 3BHL000986P0006, is a critical internal sub-assembly responsible for converting and regulating power within the drive’s inverter or control section. Its primary function is to generate the stable, low-voltage DC power rails (e.g., +5V, ±15V, +24V) required to operate the drive’s digital control boards, gate drive units, and communication interfaces from an intermediate DC bus or auxiliary AC input. The reliability and precision of the ABB FPX86-9345–B 3BHL000986P0006 are fundamental to the overall performance and availability of the multi-megawatt drive system.

Product Parameters

The technical specifications for the ABB FPX86-9345–B 3BHL000986P0006 power supply module are defined by its critical role in a high-power system:

• Module Type: Internal DC/DC Power Supply Module for ACS 6000 Drive.

• Input Voltage: Designed to operate from a specific internal DC link voltage (e.g., 600V DC, 900V DC) or a dedicated low-voltage AC auxiliary input (e.g., 230V AC).

• Output Voltages: Provides multiple, isolated, and tightly regulated DC outputs. Typical outputs include: +5V for logic circuits, ±15V for analog and op-amp circuits, and +24V for relay coils, fans, and external interfaces.

• Output Power: Rated for a specific total power output (e.g., 150W, 300W) sufficient to supply all associated control electronics in its section of the drive.

• Protection Features: Incorporates comprehensive protection including input under-voltage lockout (UVLO), output over-voltage protection (OVP), over-current protection (OCP), and over-temperature protection (OTP).

• Cooling: May be conduction-cooled via a heatsink or use forced air from the drive’s internal cooling system.

• Mounting: Designed as a plug-in card or chassis-mounted assembly within a specific compartment of the ACS 6000 inverter or control cubicle.

• Communication (Optional): May include status signals or a simple serial link for reporting health to the drive’s main controller.

Advantages and Features

The ABB FPX86-9345–B 3BHL000986P0006 power supply offers distinct advantages for high-power drive integrity:

• High Reliability in Demanding Environments: The ABB FPX86-9345–B 3BHL000986P0006 is engineered to operate reliably in the presence of high dv/dt noise, strong magnetic fields, and temperature fluctuations inside a medium-voltage drive enclosure.

• Precision and Stability: Provides exceptionally clean and stable output voltages, which is crucial for the accurate operation of sensitive control logic, analog feedback circuits, and gate drive timing.

• Compact and Integrated Design: As a dedicated ABB component, it is optimized for the space, thermal, and electrical interface requirements of the ACS 6000 drive, ensuring perfect fit and function.

• Enhanced System Diagnostics: Its health is often monitored by the drive’s diagnostic system. Failure or degradation of the FPX86-9345–B module can be reported as a specific alarm, allowing for predictive maintenance.

• Essential for System Availability: As the sole source of control power for its section, its failure will cause a drive shutdown. Its robust design directly contributes to the drive’s high mean time between failures (MTBF).

Application Cases in Industry

This internal power supply is used exclusively within ABB ACS 6000 drives deployed in heavy industry:

• Mining (Grinding Mills & Conveyors): Powers the control electronics for the drive controlling a SAG mill or a high-power overland conveyor.

• Metals (Rolling Mills): Supplies power to the control boards within the main drive for a hot or cold rolling mill stand.

• Oil & Gas (Compressors & Pumps): Provides control power in the drive for a gas pipeline compressor or a water injection pump.

• Marine Propulsion: Used in the inverter section of the drive powering the main propulsion motor of a large vessel.

• Test Benches: Powers systems in high-power motor and drive test facilities.

Comparisons with Competing Products

When compared to generic industrial power supplies or attempting component-level repair, the ABB FPX86-9345–B 3BHL000986P0006 is the only viable solution for maintaining system integrity:

• Drive-Optimized vs. Generic: A generic power supply cannot meet the specific input voltage range, output sequencing, fault signaling, and physical form factor required for seamless integration into the ACS 6000’s complex and safety-critical environment.

• Certified Performance and Safety: The original FPX86-9345–B module is part of the drive’s certified design. Using a non-OEM substitute invalidates safety certifications and introduces unknown risks of interference with the drive’s protection systems.

• Guaranteed Compatibility and Cooling: Its mechanical design ensures proper heat transfer to the drive’s cooling system. A third-party unit likely would not, leading to thermal overload and failure.

• Access to Drive Diagnostics: Only the genuine module will correctly interface with the drive’s controller for health reporting. A generic supply would render this diagnostic capability inoperative.

Selection Suggestions and Precautions

Handling and replacement of this module require expert procedures:

1. Exact Part Number Verification is Critical: The part number FPX86-9345–B 3BHL000986P0006 must be matched exactly. The suffix “B” and the long number are revisions. Using an incorrect version can cause incompatibility or damage.

2. Full Drive De-Energization and Discharge: Before replacement, the entire ACS 6000 drive must be isolated from ALL power sources (medium-voltage input, auxiliary AC, and battery backups). The internal DC link capacitors must be fully discharged using the prescribed procedure. This is high-voltage work requiring qualified personnel.

3. Electrostatic Discharge (ESD) Protection: The module contains highly static-sensitive components. Use a certified ESD wrist strap and work on an ESD surface. Handle the board only by its edges or frame.

4. Document Connections and Torque Settings: Before removal, photograph and label all connectors. When reinstalling, use the specified torque values for power terminals to ensure a safe, low-resistance connection.

5. Post-Replacement Testing Mandatory: After installation, the drive must undergo a rigorous startup and test sequence under controlled conditions, including low-voltage function tests, to verify the new ABB FPX86-9345–B 3BHL000986P0006 module and all associated controls are operating correctly before applying full power.
