RS-1209D Description

Short technical summary and product information.

The Recom Power RS-1209D is a regulated isolated DC-DC converter part of the RS series. It accepts a 2:1 input voltage range of 9V to 18V (nominal 12V) and provides a dual ±9V output at up to 111mA per output, totaling 2W. Typical efficiency is 78% with a range of 74% to 81%. The converter offers 1kVDC input-to-output isolation and includes short circuit protection (SCP) with remote on/off control (active low enable).

 

The RS-1209D is designed for ITE (commercial) applications and is suitable for industrial designs requiring isolation and regulation. It operates over an industrial temperature range of -40°C to 85°C. The maximum capacitive load for each output is ±680µF.

 

The converter is packaged in a 8-SIP module (7 leads) with through-hole mounting. Dimensions are 21.8mm (0.86") length, 9.2mm (0.36") width, and 11.1mm (0.44") height. The package material is UL94 V-0 rated.
