R1DX Thumbnail Sized DC/DC Converters

RECOM's low cost, 1 W DC/DC converters cover dual output voltage applications

RECOM extends its portfolio with the R1DX series to cover dual output voltage applications. The R1DX series is ideal for EIA/TIA-232 bus isolation and a wide range of industrial automation control equipment, sensors, isolated operational amplifiers, and test and measurement equipment that require bipolar supply voltages.

These converters are high-quality open-frame SMD converters, which deliver stable performance on symmetric dual outputs at a very competitive price. They operate from 5 V and offer ±5, ±9, ±12, or ±15 dual outputs. There is no minimum load required, and the quiescent consumption is less than 150 mW. The pin-out is industry standard and compatible with the R1S/R1D series. High isolation of up to 3 kV_DC (/H option) make them an ideal solution 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 wide temperature range from -40°C to +95°C without derating and can drive up to ±1,000 µF capacitive loads, which is currently higher than the competition. The series is fully certified to IEC/UL/EN62368-1 and UL60950-1 and is 10/10 RoHS compliant. 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.
