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