R24P21203D
24V 15W isolated DC-DC converter with 4:1 input range and dual ±12V outputs in DIP package.
Product Overview
Description
The R24P21203D from Recom is a high-efficiency 15W isolated DC-DC converter designed for 24V industrial and telecom applications. The 4:1 input voltage range (18-75VDC) accommodates both 24V and 48V nominal systems, making it ideal for distributed power architectures. The dual outputs provide +12V and -12V at 625mA each, perfect for powering operational amplifiers, data converters, and analog circuits. The 1600VDC isolation voltage ensures safety and noise immunity in industrial environments. The DIP-24 package offers excellent thermal performance and easy through-hole assembly. With efficiency up to 89%, the R24P21203D minimizes power dissipation. Comprehensive protection features include continuous short circuit protection, overcurrent limiting, and overtemperature shutdown. The wide operating temperature range (-40°C to +85°C) ensures reliable operation in harsh environments.
