Description
The NR series is an isolated DC-DC converter with wide input range, tight regulation and six-sided shielded case. Single, dual and triple output models are standard. They can operate up to 30W over the temperature range of -25°C to +70°C without derating, a heat sink or active cooling.
There are threaded inserts on the bottom to mount securely for high vibration and shock applications.
