Series NR
DC to DC Converters
Single, Dual and Triple Output

Wide Input Range up to 72V DC Input
Isolated Regulated up to 30 Watt DC-DC Converters
Single, Dual, and Triple Output Models

 

This series of high efficiency, wide input range, encapsulated regulators come in 66 different models including 30 Triple Output Models to ease board designs. These units feature a 500 VOLT DC input to output isolation in both single and dual output models. The NR Series will operate over a temperature range of -25º C TO +70º C with no heat sink or electrical derating. These units are excellent for applications where input voltage varies dramatically, yet a high efficiency and output voltage regulation must be maintained
