Isolated 20W DC/DC converters in the RP20-FR series from Recom are designed for railway applications. They are also a reliable choice for industrial and telecommunication applications, says the company.
The compact 2.0x1.0" modules feature a wide 4:1 input voltage range (9.0 to 36V, 18 to 75V, 43 to 160V) to cover all standard battery-board levels including the ±40% tolerance margin. Besides 3.3, 5.0, 12 and 15V single outputs, dual ±12 and ±15V outputs are also available. The control pin logic can be selected to be positive or negative.
The converters have an efficiency of up to 89% and feature a wide Tx operating temperature range of -40 to +85°C. Cooling is by natural convection, but the modules can be supplied with a pre-mounted heatsink, if required.
The modules are EN50155 certified with EN50121-1-3-2, EN61373 and UL/cUL-60950-1 approvals. They carry the company’s standard three-year warranty.
