D10-240p1a Schematic May 2026

The Lite-On D10-240P1A is a 240W, 80 Plus Gold internal PSU used in HP ProDesk 600 G1 and EliteDesk 800 G1 SFF computers. While official schematics for this 6-pin proprietary unit are not publicly released, it typically features active PFC and synchronous rectification, with common failure points including the main fuse, standby rails, and startup capacitors.

  1. Power Input Stage: This section of the schematic would illustrate the power input connections, including the voltage and current ratings.
  2. Converter Stage: This stage would show the conversion of the input power to the desired output voltage and current.
  3. Control and Regulation: This section would depict the control and regulation circuitry, including feedback loops and voltage regulators.
  4. Output Stage: This final stage would illustrate the output connections, including the voltage and current ratings.

This wasn't a loom controller. It was a stabilizer. A massive, over-engineered harmonics filter. D10-240p1a Schematic

Q2: Can I run the D10-240p1a on 110V AC only?

A: Yes, the universal input stage (bridge rectifier) supports 100-240V. However, at 110V, the primary current doubles. Ensure your input fuse is rated for this (T10A instead of T6.3A if you are consistently at 110V). The Lite-On D10-240P1A is a 240W, 80 Plus
