Murata – New 16 / 160VDC input 15W DC-DC converter suits transportation applications (RUW15)

Murata power Solutions’ RUW15 series of 15W ultra wide range single-output isolated DC-DC converters are aimed at transport and industrial applications where the input voltage may vary widely and a hold-up capability is required.

Accommodating an extremely wide input range from 16 to 160VDC, the RUW series therefore has a high immunity to input surges and is able to “ride-through” drop-outs of indefinite duration across the input range by addition of a relatively small external capacitor. For example the output can be maintained for up to 120ms at full load from any input when using a 900uF capacitor.

The series comprises 3 models providing the nominal outputs of 5, 12 or 24VDC. Input to output isolation complies with the internationally recognized standard UL 60950 for reinforced isolation of up to 4kVAC test voltage. A DC OK / Power Fail signal gives an advance warning of typically 2ms of the impending loss of output. Measuring 50.8mm x 50.8mm x 20mm, the RUW15 protection features include over-load, over-temperature, output short-circuit and output over-voltage.
