HP HVPS24V 21.6V 27.6V Max 7Kv Max-2Kv M45

In a busy office print room, the HP M45 High Voltage Power Supply quietly enables crisp, reliable laser output. This internal DC-DC module converts a nominal 24V DC input into the dual high voltages required by modern imaging systems, delivering up to +7 kV for the primary corona and -2 kV for the transfer roller. Service technicians and refurbishers rely on it as a direct OEM replacement for HP laser printers and copiers, restoring full print quality without guesswork.

Key specifications

• Nominal input voltage: 24V DC (range 21.6V – 27.6V DC)
• Maximum positive output: +7 kV DC
• Maximum negative output: -2 kV DC
• Dual polarity output for corona and transfer functions
• Compact internal power module for OEM integration
• Designed for HP laser printer/copier imaging systems

Why choose it

This HVPS is engineered to HP's exacting standards, ensuring stable high-voltage output that prevents print defects like faded images or background scatter. Its wide input voltage tolerance makes it resilient to minor power fluctuations, while the dual outputs cover both charging and transfer stages in one unit. For repair shops, it eliminates the need to source multiple components, cutting downtime and inventory costs.

Ideal use cases

• Replacing a failed HVPS in HP laser printers or MFPs
• Refurbishing used HP printing equipment for resale
• Maintaining a fleet of office printers with a spare module
• Integrating into custom laser imaging systems requiring dual high voltage

Good to know

Installation should be performed by qualified personnel, as the module generates dangerous voltages even after power is removed. Always discharge capacitors before handling. The module is not user-serviceable; no internal adjustments are required. Verify compatibility with your specific HP model before ordering, as pinouts and mounting may vary across product lines.
