DATEL’s UER Model single-output switching DC/DC converters were designed for

cost-sensitive, moderate-power (12-15 Watts) applications requiring a reliable, off-the-

shelf solution but not demanding all the high-performance characteristics of DATEL’s A-

Series UWR Model converters. Offering slightly wider electrical tolerances and slightly

lower power densities (8.33W/in3), UER devices achieve their low cost through the use

of plastic packaging (UL94V-0 rated material) and the exploitation of traditional, yet

highly automated, SMT-on-pcb construction techniques. The result is a contemporary

power converter whose cost/performance/reliability ratio far exceeds the competition.

UER Model DC/DC converters offer the ultra-wide, 9-to-36V and 18-to-72V, input

voltage ranges that have come to be associated with DATEL power converters. Output

voltages are 3.3V, 5V, 12V or 15V. Line and load regulation are both guaranteed not to

exceed ±1%. All models incorporate internal input/output filtering and require no

external components for normal operation. All units guarantee output ripple/noise less

than 100mVp-p.

These fully isolated (750Vdc guaranteed) devices are input overvoltage and

reverse-polarity protected and employ output current limiting to protect both the power

converter and its load. They offer VOUT trim and remote on/off control capabilities. They

function well in harsh environments and are popular for both commercial and industrial

usage in computer, telecom, aerospace and process-control applications.

The industry-standard, 2" x 2", package size and pinout of the UER Models makes

them ideal replacements for other, more costly, less reliable power converters. They

are equally well suited for new design-ins in systems demanding both low cost and high

reliability.
