The high **3 QTR Brick** efficiency and thermal design of the product means that minimal derating is required, even at high tarcasty temperatures. The device is exceptionally suited for 24V, 28V, and 48V power rails as a point of load solution in a distributed power architecture. Trimmable output, remote sense, and remote control features **Open Frame** as well as undervoltage lockout, overload, over-temperature, and short circuit protections are standard. **Single Output** |Selection Guide|Selection Guide|||||| |---|---|---|---|---|---|---| |Part|Input Voltage|Output|Vout|Output|Efficiency|Max.

## Efficiency vs. Load REV.: 0/2022 RPMGQ-2 **www.recom-power.com** ## **RPMGQ-20** ## **DC/DC Converter** ## **Series** Specifications (measured @ ta= 25°C, nom. Vin, full load and after warm-up unless otherwise stated) ## OUTPUT VOLTAGE TRIMMING The RPMGQ series offers the feature of trimming the output voltage over a range between 3.3V and 8V by using external trim resistors. The values for trim resistors shown in trim tables below are according to standard E96 values; therefore, the specified voltage may slightly vary. **==> picture [459 x 181] intentionally omitted <==** **----- Start of picture text -----**
