PRODUCT OVERVIEW
The NCS12 series of DC/DC converters offers
single & dual output voltages from input voltage
ranges of 9-36V and 18-75V. The NCS12 is
housed in an industry standard package with
a standard pinout. The NCS12 is packaged in a
metal case for improved EMI shielding and is also
encapsulated for superior thermal performance.
Applications include telecommunications, battery
powered systems, process control and distributed
power systems.
