DATEL's Model dual-output switching DC/DC converters were designed cost-sensitive, moderate-power Watts) applications requiring reliable, off-theshelf solution demanding high-performance characteristics DATEL's ASeries Model converters. Offering slightly wider electrical tolerances slightly lower power densities (8.33W/in3), devices achieve their cost through plastic packaging (UL94V-0 rated material) exploitation traditional, highly automated, SMT-on-pcb construction techniques. result contemporary power converter whose cost/performance/reliability ratio exceeds competition. Model DC/DC converters offer ultra-wide, 9-to-36V 18-to-72V, input voltage ranges that have come associated with DATEL power converters. Output voltages ±5V, ±12V ±15V. Line load regulation guaranteed exceed ±0.5% ±1%, respectively. models incorporate internal input/output filtering require external components normal operation. units guarantee output ripple/noise less than 100mVp-p. These fully isolated (1000Vdc typical) devices input overvoltage reversepolarity protected employ output current limiting protect both power converter load. They function well harsh environments popular both commercial industrial usage computer, telecom, aerospace industrial-control applications. industry-standard, package size pinout Models makes them ideal replacements other, more costly, less reliable power converters. They equally well suited original design-ins systems demanding both cost high reliability.
