Models in the regulated and isolated RPA40-FR series feature a 36 to 160V input range (200V/1 sec) which includes rail nominals of 72, 96 and 110V with surges and dips. Low noise, single and dual output models available are 5.0, 5.1, 12, 15, 24, ±12 and ±15V with the single outputs’ trimmable minimum ±10%. The 15 and 24V models are trimmable to 20/-10%). No minimum load is required.

According to Recom, the DC/DC converters set a standard for power density and cost-effectiveness with 40W output in an industry-standard) board-mount through-pin package and a form factor of 50.8 x 25.4 x 10.2mm (2.0 x 1.0 x 0.4 inches.

The efficiency of the RPA40-FR series peaks at 90%. This performance is coupled with a thermal design which allows operation with natural convection to high temperatures without derating up to 105°C ambient with reduced load and/or airflow. Safety features are over-temperature, input under-voltage, output over-current, and short circuit protection. A control pin is also provided to shut down the DC/DCs into a low dissipation state.

The DC/DC converters are designed to multiple safety certifications, which include UL/EN/IEC 62368-1, EN 45545-2 and EN 50155, with a reinforced isolation rating of 3kVAC/1 min. The converters meer EMC specification EN 55032 class A without external components andclass B can be met with a simple external filter network.

The DC/DC converters are reliable with a MTBF of 1.25MHrs at 25°C according to MIL-HDBK 217-F (GB). These characteristics make the rugged, encapsulated RPA40-FR DC/DC converters suitable for harsh rail environments as well as for general industrial use.

The parts are covered by a three-year warranty. Samples and OEM pricing are available from all authorised distributors or directly from Recom.
