Datasheet
Datasheet Summary
Powered by GS/AI

The U4Y003J is a 400W AC-DC power supply with a 12V output, featuring a cover and chassis with an end-mounted, temperature-controlled fan. It operates from 90-264Vac input at 45-63Hz, meets EN61000-3-2 harmonic compliance, and has reinforced 3kVac isolation between input and output. The unit delivers 530W peak power for 10 seconds, maintains total regulation better than 4%, and achieves up to 90% efficiency. It complies with EN61000-6-3 and EN55032 Class B emissions, is certified to IEC/EN 62368-1, UL62368-1, and CSA 22.2 No. 62368-1, and carries CE and UKCA markings. Dimensions are 152.4mm x 100mm x 46.74mm, with a non-user-accessible fuse and a 12V/0.25A fan supply integrated into the chassis. Operation is rated from 0°C to 50°C with derating above 50°C. The unit includes automatic recovery for overcurrent and overtemperature events, and latching overvoltage protection requiring AC restart.
