GE A06B-6087-H130 Power Supply

The GE Fanuc A06B-6087-H130, also cataloged as the A06B-6087-H130 Power Supply Unit (PSM-30), operates as a dedicated hardware component for AC to DC power conversion within GE Fanuc Alpha Series drive architectures. It rectifies incoming 200-230 VAC 3-phase line power into a regulated DC link voltage, supplying high-current DC power up to 127 A to downstream servo and spindle amplifier modules across shared bus bars.

Hardware Specifications

Backplane Bus Communication Velocity and Power Management

The A06B-6087-H130 links to host CNC controllers and amplifier racks through dedicated communication interconnects. Operating within high-velocity control loops, the module coordinates power regeneration and dynamic braking sequences to prevent DC link overvoltage conditions. Internal thermal heat sink dissipation profiles dissipate thermal energy under continuous heavy load cycles, while firmware flash compatibility across Alpha Series drive components ensures synchronized fault signaling and instant emergency shutdown execution during phase loss or overcurrent events.

Frequently Asked Questions

Q: Does the A06B-6087-H130 Power Supply Module support hot-swapping under live power conditions?

A: No, hot-swapping is strictly prohibited. The main 200-230 VAC line power must be fully de-energized and locked out, and high-voltage DC link capacitors allowed to discharge completely before servicing or replacing module connections.

Q: What is the purpose of the shared DC bus bar connection on this power module?

A: The shared DC bus bar distributes the rectified 300 VDC power output directly from the PSM-30 module to adjacent Alpha Series servo and spindle amplifiers, eliminating individual AC line feeds for each drive module.

Field Installation Guidelines

1. Disconnect and lock out main 3-phase AC power feeds to the electrical cabinet, allowing internal capacitors to discharge for at least 10 minutes.
2. Measure voltage across the high-voltage DC link bus terminals using a calibrated digital multimeter to verify potential has dropped below 50 VDC.
3. Secure the module onto the panel backplate using specified mounting hardware, ensuring direct metal-to-metal contact with the grounded subplate for electrical grounding integrity.
4. Install solid copper bus bars between the PSM-30 DC output terminals and adjacent amplifier modules, torquing terminal screws to specified torque values (2.0 Nm to 2.5 Nm).
5. Verify 200-230 VAC 3-phase line wiring connections (R, S, T) and grounding conductor integrity before re-applying main power.
