The DC/DC converter series is suited to 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 open-frame, surface mount converters deliver stable performance on symmetric dual outputs at a very competitive price, says the company. 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 company’s R1S/R1D series. High isolation of up to 3kVDC (/H option) makes them 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 wide temperature range from -40 to 95°C without derating and can drive up to ±1000µF capacitive loads, which is multiple times higher than the competition, according to the company.

The converters are certified to IEC/UL/EN62368-1 and UL60950-1 and conforms to 10/10 RoHS. Class A EMC conformity requires only an input capacitor and a low cost LC filter for Class B EMC.

Samples are now available from authorised distributors.
