Restore reliable power and stable performance in your Xerox AltaLink B81xx / C81xx machine with this OEM 112-Series Low Voltage Power Supply (LVPS) Assembly. Delivers clean, regulated voltage to essential internal components to prevent power-related errors, fan failures, and unexpected shutdowns.

In complex multifunction printers such as the Xerox AltaLink B81xx / C81xx series, the low voltage power supply (LVPS) is the heart of stable internal power. Without consistent low voltage, critical components like controller boards, sensors, motors, and cooling fans may not function correctly — leading to errors, dropped connections, system instability, or even failure to boot.

The 112-Series LVPS Assembly (OEM part number 112K91400 and associated revs like 112K91511, 112K91610) is engineered to replace failing units and restore full operational health. It’s designed to deliver multiple stable low voltage rails under load, maintain performance in elevated ambient conditions, and interface correctly with the printer’s power and cooling architecture.

This assembly is compatible with:

• AltaLink B8145, B8155, B8170

• AltaLink C8130, C8135, C8145, C8155, C8170

Replacing a faulty LVPS can eliminate symptoms such as:

• Random shutdowns or reboots

• Errors related to fan failure (or fan not spinning)

• Faults related to sensors or logic boards losing power

• Reduced print reliability or inability to handle duty cycle

Installation should be performed by trained technicians. Ensure power is completely disconnected, observe proper ESD (electrostatic discharge) precautions, verify the unit’s cooling fan / vent path is clear, test after installation, and monitor for correct operation before returning the machine to full service.
