The A300RU series 3W dc/dc converters provide an ultra-wide 4:1 input range, offer single and dual outputs, and promise tight regulation and low-noise operation. Twelve models operate from inputs of 9 to 36 Vdc or 18 to 75 Vdc, providing outputs of 3.3, 5, 12, 15, ±12, or ±15 Vdc. Standard features include efficiencies up to 84%, a line/load regulation of ±1%, an input/output isolation of 1.5 kVdc, and compliance with EN55022. Other features include output-power protection and continuous short-circuit protection with auto recovery. MICROPOWER DIRECT, Stoughton, MA. (781) 344-8226.
