DATEL's Model, 25-40 Watt, dual-output DC/DC converters bring efficient "on-board" power processing cost-effective smaller package with standard pinout. "footprint" conforms industry-standard pinout geometries most devices space savings) while delivering much more power (40W 25W). Applicable wide range telecom, computer other applications, Model DC/DC's offer ±5V, ±12V ±15V outputs. They operate from four different input voltage ranges with total available output power being function selected input range. "Q12" models operate from 10-36V deliver 25W. "Q48" models operate from 18-72V deliver 30W. "D24" "D48" models, input voltage ranges rated output powers 18-36V 36-72V 40W, respectively. improved reliability affordability, Models exploit modern, high-speed, automatic assembly construct their field-proven, SMT-on-pcb designs. Devices employ corrosion-resistant steel cases with heavy zinc plates (traditionally referred baseplates). Heat-generating transformer cores power semiconductors mounted directly cases, which have threaded inserts optional add-on heat sinks and/or mounting. devices feature input filters, input overvoltage shutdown, output overvoltage protection, output current limiting, thermal shutdown. CSA, compliance testing currently progress EMI/EMC characterizations.

Common (pin should left open. Minimum loading recommended under these conditions. total output voltage span externally trimmed described below. Filtering Noise Reduction 25-40 Watt DC/DC Converters achieve their rated ripple noise specifications without external input/output capacitors. critical applications, input/output ripple noise further reduced installing electrolytic capacitors across input terminals and/or low-ESR tantalum electrolytic capacitors across output terminals. Output capacitors should connected between their respective output (pin Common (pin Figure caps should located close power converters possible.

Output Power Model, dual-output DC/DC converters incorporate design tradeoff between total available output power input voltage range. total available power function both nominal input voltage "width" input voltage range. given nominal input (24V 48V), narrower ranges (2:1 4:1) have more available power. given "width" input range (2:1 4:1), higher nominal inputs (48V 24V) have more available power. Each device, indicated part-number suffix (Q12, Q48, D48) total output power limitation Watts, respectively. Observing these power limitations user's responsibility. indicated Part Number Structure, each ±5V, ±12V ±15V device capable sourcing ±1.65 ±1.3 Amps, respectively. Users have flexibility loading either output these limits; however must extremely careful exceed total output power rating given device. example, device with power rating (BPB-5/4-Q48) sourcing from output (representing +Output power), that device only supply additional Amps) from -Output. consequence this "power-allocation" flexibility, definition "full load," condition under which performance specifications tested listed, ambiguous. following table lists positive negative output currents that DATEL uses define each device's "full load."
