Ideal for transportation applications that require a long hold-up time
Murata today announced the Murata Power Solutions RUW15 series of 15 W ultra wide 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 VDC, 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 120 ms at full load from any input when using a 900 uF capacitor.
The series comprises 3 models providing the nominal outputs of 5, 12 or 24 VDC. Input to output isolation complies with the internationally recognized standard UL 60950 for reinforced isolation of up to 4 kVAC 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.
