RUW15 Datasheet, PDF (3/5 Pages) Murata Manufacturing Co., Ltd. – Isolated Ultra-Wide Input DC/DC Converters

RUW15 Series
Isolated Ultra-Wide Input DC/DC Converters
OPTIONAL FEATURES
Hold-up
Hold-up time is dependent on the value of capacitance across -VINT and +VINT. The graph below shows the approximate hold-up time for a given capacitance.
The active hold-up feature typically requires 60 seconds to fully reset between supply interuptions. Capacitor voltage rating should be 100VDC minimum.

Power Fail Warning Details
The optional Power Fail/DC OK signal gives an advance warning of loss of output after input failure (typically 2ms) and an indication that the output voltage is within specification.
