Accommodating a 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 three 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.
