The TU425S18E is part of the TU425 Family of industrial-grade AC/DC converters from SL Power Electronics. This open frame unit provides a nominal 18V output and can deliver up to 300W of power under convection cooling conditions, or 425W with 200 LFM of forced air. It accepts a universal input voltage range of 90-264VAC.
Key features include a typical efficiency of 90%, an isolated 12V fan output, and a 5V at 2A isolated standby output. The converter also offers Inhibit, Power Fail, and DC OK signals, along with Remote Sense capability. Its dimensions are 6.20" L x 3.30" W x 1.62" H (157.4mm x 83.8mm x 41.1mm), making it suitable for chassis mounting.
Designed for ITE (Commercial) applications, the TU425S18E meets high levels of EMC per EN61000-4, with Class B conducted EMI and Class A radiated EMI. It is approved by CE, cURus, and DEMKO, and complies with EN/CSA/IEC/UL62368-1 safety standards. The operating temperature range is -10°C to 70°C with derating.
The nominal output voltage is 18V.
