1W DC/DC converters add dual outputs to increase application options

Recom has extended its R1SX 1W DC/DC converters, adding the R1DX series to cover dual output voltage applications. The R1DX series is particularly suitable for EIA/TIA-232 bus isolation and a range of industrial automation control equipment, sensors, isolated operational amplifiers and test and measurement equipment that require bipolar supply voltages.

The R1DX series are high-quality open-frame surface mount converters, which deliver stable performance on symmetric dual outputs at a very competitive price, says Recom. They operate from 5.0V and offer ±5, ±9, ±12 or ±15 dual outputs. There is no minimum load required, and the quiescent consumption is less than 150mW. The pin-out is industry standard and compatible with the R1S/R1D series. High isolation of up to 3kVDC (/H option) makes the R1DX series suitable for isolating data transfer lines in legacy communication protocols (e.g. RS-232) and for isolated DAC and sensor applications. The modules operate at a temperature range from -40 to +95 degree C without derating and can drive up to ±1000-microF capacitive loads, which is multiple times higher than competing options, claims the company.

The series is fully certified to IEC/UL/EN62368-1 and UL60950-1 and is 10/10 RoHS-conform. Class A EMC conformity requires only an input capacitor and a simple low cost LC filter is all that is needed for Class B EMC. Samples are now available from all Recom authorised distributors.
