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.

NCS12 Series Isolated 12W 4:1 Input Single & Dual Output DC/DC Converters EMC FILTERING AND SPECTRA FILTERING The module includes a basic level of ﬁltering, sufﬁcient for many applications. Where lower noise levels are desired, ﬁlters can easily be added to achieve any required noise performance. A DC/DC converter generates noise in two principle forms: that which is radiated from its body and that conducted on its external connections.
