“Dc-dc for rail applications typically operate from 72V, 96V, or 110VDC nominal input with dips and surges,” according to the company.
There are 10W (RP10-RAW), 6W (RP06-RAW) and 3W (RP03-RAW) types, with individual models offering a choice of single outputs: 3.3, 5, 12, 15 or 24V, or dual outputs: ±5, ±12 or ±15V.
Packaging is 31.8 x 20.3 x 10.6mm tall.
Nothing is for free, so the variation of power in the same envelope means that the 3W parts can work convection cooled at full power to 90°C, 6W types to 85°C and 10W versions to 75°C.
Forced air flow will push these max full-power temperatures up and, with derating, all of them can deliver something up to 105°C. All work down to -40°C.
Isolation is reinforced to 3kVac and certifications include EN50155 as well as IEC/EN/UL62368, and the Canadian equivalent said Recom, adding: “EN55032 class A EMC is met without additional components, while class B can be met with the addition of three external capacitors.”
2MOPP operation to IEC60601-1 is possible if a keep-out zone on the PCB is respected – see the data sheets.
Protection is included against input under-voltage, output over-voltage, over-temperature, short-circuit and over-current. A shutdown control is pin is provided.
Warranty is three years.
“These dc-dcs are ideal as auxiliary supplies in the harsh rail environment,” said Recom product manager Matthew Dauterive. “They could also be used in wider industry where higher supply voltages are seen, such as in battery management, forklift trucks and IoT sensors.”
