Wide Input voltage range 9 - 36 Vdc 17 - 36 Vdc ! Efficiency to 85% ! Pi Input filter ! Six-sided shielding ! Regulated outputs T he N Series are high quality, wide-input, efficient 15 and 40 watt DC/DC converters. Features include: Pi input filtering to reduce input reflected ripple, and efficiencies to 85%. Other key features include: overvoltage protection, output trim adjustability (10%), and continuous short circuit protection. Packaged in a six-sided shielded case, the 15 watt N Series measures only 2.0" x 2.0" x 0.4". Packaged in a six-sided shielded case, the 40 watt N Series measures only 2.5" x 3.5" x 0.83". Applications The N Series is designed for batterypowered or portable, space-critical applications, as well as other applications not requiring input-output isolation. 1 N Series Ordering Information Input Voltage Range Output Voltage Output Current Case Model Number 9-36 Vdc 5 Vdc 3000mA 1 NA11-300-18 9-36 Vdc 5 Vdc 8000mA 2 NC11-800-18 9-36 Vdc 5 Vdc 8000mA 3 NW11-800-18 17-36 Vdc 12 Vdc 3300mA 2 NC12-330-18 17-36 Vdc 12Vdc 3300mA 3 NW12-330-18 Dimensions and Connections NOTES: 1.
