UHE-12/2500-Q48-C

The UHE 12-30W Series of high-efficiency, isolated DC/DC’s provide output power ranging from 10 Amps @ 1.2V to 2 Amps @ 15V. Offering both 2:1 and 4:1 input voltage ranges, UHE’s meet VIN requirements from 9 to 75 Volts.Taking full advantage of the synchronousrectifier, forward topology, UHEs boast outstanding efficiency (some models exceed 91%) enabling full-power operation to ambient temperatures as high as +60°C, without air fl ow. Assembled using fully automated, SMT-on-pcb techniques, UHEs provide stable no-load operation, excellent line (±0.1%) and load (±0.15%) regulation, quick step response (200µsec), and low output ripple/noise (50-100mVp-p). Additionally, the UHEs unique output design eliminates one of the topology’s few shortcomings–output reverse conduction.All devices feature full I/O fault protection including: input overvoltage and undervoltage shutdown, precise output overvoltage protection (a rarity on low-voltage outputs), output current limiting, short-circuit protection, and thermal shutdown.All UHE models incorporate a VOUT Trim function and an On/Off Control pin (positive or negative logic). Low-voltage models (1.2V to 5V) offer optional sense pins facilitating either remote load regulation or current sharing for true N+1 redundancy. All models are certifi ed to the BASIC insulation requirements of UL/EN60950-1 (2nd Edition), and 48VIN (75V max.) models carry the CE mark. Selected models are RoHS compliant (Reduction of Hazardous Substances).
