Overview
IEC Power Entry is an open-source printed circuit board by baseonmars, from the baseonmars/iec-power-entry-module repository on GitHub. It is a 2-layer board of 75.5 × 80 mm with 14 parts on 8 nets, routed with 33 tracks and 0 vias.
It is built around the V80212MS02Q and DD21.0121.1111. Its parts include 4 connectors and 1 switch.
Main components
2README
README.mdUniversal IEC Power Inlet with Voltage Surge and Current Inrush Limiting
I find myself needing a power entry solution when working on amps and other audio related equipment with linear power supplies.
This is my attempt at creating a reusable board
## Features
- IEC C14 socket
- Dual fuse holder
- Power switch
- Voltage selection for US and EU voltages when using a dual primary transformer
- MOV for voltage surge suppression
- NTC thermistor for current inrush limiting
Bill of Materials
- Schurter DC21 power inlet with power switch
- Schurter 4301.1405 fuse drawer
- V&K V80212MS02Q voltage selector switch
- MOVs 7.5mm pitch, max diameter 12mm, max width 5mm *
- EPCOS / TDK Inrush Current limiter* pitch 7.5mm, max diameter 12mm, max width 7mm
- You must select an adequate voltage and inrush limiter for your target application.
Safety Note
This schematic and associated designs and files are provided without any guarentee of safety. Please do your research and use at your own risk.
This is very much a work in progress - this notice will be removed when I have greater confidence in the design.

Questions
How big is the IEC Power Entry PCB?
It measures 75.5 × 80 mm and has 2 copper layers, 1.6 mm thick.
What parts does the IEC Power Entry use?
14 parts, built around the V80212MS02Q and DD21.0121.1111. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the IEC Power Entry KiCad files?
From the baseonmars/iec-power-entry-module repository on GitHub, at the commit this page was made from: the board is IEC Power Entry.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the IEC Power Entry design in my own project?
Its repository states no licence, so its author keeps all rights: ask baseonmars before reusing the design.
