The Recom Power RB-1209S is a 1W isolated DC/DC converter module from the RB series. It provides a regulated 9V output from a nominal 12V input (10.8V to 13.2V range), delivering up to 111mA of output current. The converter offers 1kVDC/1s isolation between input and output, making it suitable for general purpose power rail isolation and conversion.
Key electrical characteristics include a typical efficiency of 78% at full load, a maximum output ripple and noise of 100mVp-p, and an internal operating frequency of 50kHz to 105kHz. The module can drive a maximum capacitive load of 1000µF and requires no minimum load for operation. It includes short circuit protection (SCP) as a feature.
The RB-1209S is housed in a compact 7-SIP module with 5 leads and a through-hole mounting style. Its dimensions are 19.7mm x 6.0mm x 10.2mm. The device is designed for commercial ITE (Information Technology Equipment) applications and operates over a temperature range of -40°C to +85°C.
