Murata Power Solutions | ULS-12/5-D48N-C

The ULS-12/5-D48N-C is a part of ULS series 60 W isolated DC/DC converter. The ULS series makes another dramatic size shrink down to a “sixteenthbrick” width (0.9 inches) while still retaining up to 66 Watt output and full 2250 Volt DC isolation. The PC-board mount converter family accepts 36 to 75 Volts DC inputs and delivers fixed outputs regulated to within ±0.2%. The world of “brick” DC/DC converters has seen a steady size reduction.

The ULS outputs may be trimmed within ±10% of nominal output while delivering fast settling to current step loads and no adverse effects from higher capacitive loads. Excellent ripple and noise specifi cations assure compatibility to circuits using CPU’s, ASIC’s, programmable logic and FPGA’s. No minimum load is required. For systems requiring controlled startup/shutdown, an external remote On/Off control may use a switch, transistor or digital logic. Remote Sense inputs compensate for resistive line drops at high currents.
