AA04S1200A

The AA04S1200A is a 4W single-output AC/DC converter module from Delta Electronics, part of the AA04S/D series. It provides a regulated 12V output at 333mA with typical efficiency of 76%. The module accepts universal AC input from 85 to 264VAC at 47-440Hz, or DC input from 120 to 370VDC. It is enclosed in a 7-DIP module with through-hole mounting, measuring 36.5mm x 27.0mm x 17.1mm.

Key electrical features include line and load regulation within ±0.5% typical, output voltage accuracy of ±1%, and low ripple and noise of 0.8% VPP typical. The module incorporates over voltage protection (120% of Vo), short circuit protection (hiccup mode), and current limitation (105% of Inom). Isolation voltage is 3kVAC, and the module is Protection Class II. No-load power consumption is 0.3W maximum.

The converter is designed for commercial ITE (Information Technology Equipment) applications and is certified to UL/IEC/EN 60950-1, CE marked, and meets EMI EN55032 Class B and EMS EN61000-4 standards. It is RoHS compliant and lead-free. The module requires no minimum load, and maximum capacitive load is 330μF. Operating temperature range is -25°C to 60°C with derating. Warranty is 3 years.
