1 D Series, 10- Input Ranges : 9-75 VDC : Single 3.3V - 24V Bipolar ±5.0V, ±12V, ±15V Dual +5.0V / Triple +5.0V / ±12V +5.0V / ±15V Power: 6.6 to 15 W The D series DC-DC converters feature high power density, high efficiency and excellent line & load regulation. Using innovative design technique, state-of-the art Current Mode PWM control, and Surface Mount packaging & manufacturing technology, the D series provides up to 15 watts of well regulated power in a encapsulated 1.0 x 2.0 x 0.40 metal case with six-sided EMI/RFI shielding. Automatic feed forward compensation, pulse-by-pulse current limiting, and output short circuit protection are standard for all models. These converters are designed for wide input range telecommunications, industrial and instrument applications. The wide input range (2:1 & 4:1) is ideal for battery or unregulated input applications. FEATURES General: Small footprint : 1.0 x 2.0 Current-Mode Control Input/ Isolation Input from 9 to 75Vdc 2:1 & 4:1 Input Range High conversion efficiency: 80% Line & load regulation to ±1.0% Fixed operating frequency Six-Sided Shielding Isolation: Isolation >500V APPLICATIONS PoE (Power over Ethernet) Distributed Power Systems Workstations puter Equipment munications Equipment No external components are needed for normal operation. Low ESR capacitors are used to minimize the conductive noise. This package is ideal for all I/O board system and distributed DC power configurations.
