PRODUCT OVERVIEW

The NCS6 series of DC/DC converters offers

single & dual output voltages from input voltage

ranges of 9-36V and 18-75V. The NCS6 is housed

in an industry standard package with a standard

pinout. The NCS6 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.

NCS6 Series Isolated 6W 4:1 Input Single & Dual Output DC/DC Converters TECHNICAL NOTES ISOLATION VOLTAGE ‘Hi Pot Test’, ‘Flash Tested’, ‘Withstand Voltage’, ‘Proof Voltage’, ‘Dielectric Withstand Voltage’ & ‘Isolation Test Voltage’ are all terms that relate to the same thing, a test voltage, applied for a specified time, across a component designed to provide electrical isolation, to verify the integrity of that isolation.
