Murata Power Solutions announced the UWS series of 50 Watt medium power isolated DC/DC converters that are available in either through-hole or surface mount configurations. Meeting the DOSA standard for sixteenth brick dimensions of 1.31 inch x 0.91 inch x 0.36 inch, these units accommodate the input range of + 18 to + 75 VDC around a nominal 48 VDC.

Input to output isolation is rated at 2,250 VDC so that the output is protected from spikes, transients and noise on the input. Within the series there are three models offering outputs of 3.3, 5 or 12 VDC. Up to 54 W output is available without the need for any forced air cooling. The 12 VDC unit suits regulated intermediate bus applications. The outputs are regulated to within ± 0.125% across all load conditions.

Also, the outputs may be trimmed ± 10%, 3.3 VDC model, or +10% to -20% for the 5 and 12 VDC models allowing the user to compensate for voltage losses. Suiting a range of data and telecommunications applications, the UWS series has many self-protection controls such as overcurrent, overvoltage, input undervoltage and overtemperature shutdown.

For systems requiring controlled startup and shutdown, an external remote on/off control may be driven by a switch, transistor or logic signal. This control can be selected as either positive or negative polarity. Accommodating a range of operating temperature from - 40 degrees C to + 85 degrees C the series has guaranteed operation over the normal industrial range.

The UWS series complies with the internationally recognized safety standards UL/EN 60950-1 and CSA-C22.2 No. 60950-1 2nd editions for IT and commercial equipment.
