# RaToPUS, radiation tolerant AC-DC power supply
|
|
|
|
|
|
## Project description
|
|
|
|
|
|
Radiation-tolerant AC/DC power supply unit (PSU). In: 230VAC, 50Hz, Out: +12V, 8.33A (100W) and +5V, 2A (10W). Possibility for redundancy. The design is CompactPCI compatible. Part of DIOT project.
|
|
|
**Disclaimer:**<br>
|
|
|
**Manufacturing the power supply according to the design published in this project does not ensure it will be resistant to radiation. Only using the components from a lot qualified in irradiation campaign guarantees that this power supply will withstand the radiation levels mentioned in the specification.**

*SPEC 1.1 first prototype**
|
|
|
RaToPUS is a 100W AC/DC power supply compatible with the CompactPCI-Serial standard (CPCI-S.0). It is designed in the frame of the Distributed I/O Tier project to be used in radiation-exposed installations of the HL-LHC at CERN.

## Architecture
|
|
|
RaToPUS is designed in two stages:
|
|
|
- AC/DC stage: 230VAC to 48VDC
|
|
|
- isolated DC/DC stage: 48VDC to 12VDC and 5VDC
|
