The XP Power ACS40US12 is an open-frame AC-DC converter designed for ITE (Commercial) applications. It delivers 40W of output power with a nominal 12V output voltage and a maximum continuous current of 3.34A.
This converter offers a universal input voltage range of 90-264 VAC and operates at a switching frequency between 50-70 kHz. Key electrical specifications include a typical efficiency of 84%, line regulation of 0.5% max, and load regulation of 1.0% max. It provides robust isolation with 3000 VAC input to output.
Mechanically, the ACS40US12 features a chassis mount design with dimensions of 101.6mm x 50.8mm x 30.5mm. It operates within an ambient temperature range of 0°C to 70°C, with derating applied at higher temperatures. The unit meets various EMC and safety standards, including FCC20780 Level B and EN62368-1.
The operating temperature range is 0°C to 70°C, with derating from full load at 50°C to half load at 60°C. When a cover is fitted, temperatures are reduced by 10°C.
The input voltage range is 90-264 VAC (47-63 Hz) or 110-370 VDC.
The output voltage is 12 V nominal, and the output current is 3.34 A nominal, providing 40W of power.
Typical efficiency is 84%.
It is approved to EN62368-1, UL62368-1, CE, and UKCA.
MTBF is 230,000 hours per MIL-HDBK-217F.
The dimensions are 101.6mm x 50.8mm x 30.5mm (4.00" x 2.00" x 1.20").
