Murata has announced the Murata Power Solutions RUW15 series of 15-W single-output isolated DC-DC converters 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 160 V DC, the RUW series has a high immunity to input surges and is able to ride-through dropouts 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 120 ms at full load from any input when using a 900-?F capacitor. The series comprises three models providing the nominal outputs of 5, 12 or 24 V DC. Input to output isolation complies with the internationally recognized standard UL 60950 for reinforced isolation of up to 4 kV AC test voltage. A DC OK/Power Fail signal gives an advance warning of typically 2 ms of the impending loss of output. Measuring 50.8 x 50.8 x 20.0 mm, the RUW15 protection features include overload, over temperature, output short circuit, and output over voltage. Murata
