ROE-2405S Recom Power ROE-2405S Isolated Through Hole Module DC DC Converter

The RECOM POWER ROE-2405S is a compact, cost-effective, and highly reliable unregulated isolated DC/DC converter designed for general-purpose power isolation and voltage matching applications. Housed in a 4-pin SIP (Single Inline Package), this 1W converter provides efficient power conversion with robust industrial-grade performance. Featuring a 1:1 input-output ratio, it converts a 24V input to a stable 5V DC output at 200mA, making it suitable for various low-power industrial and ITE (Information Technology Equipment) applications.

With 1kVDC isolation, high efficiency (up to 80%), and an extended operating temperature range of -40??C to +85??C, the ROE-2405S ensures reliable performance in demanding environments. Additionally, it complies with key safety standards, including UL60950-1 and CAN/CSA C22.2 No. 60950-1-07, ensuring suitability for industrial, medical, and communications systems requiring isolated power supplies.
