Lineage Power JNC350R Series
Isolated Power Modules
18-36Vdc Input; 28Vdc Output; 350W Output

GE Energy (Formerly Lineage Power)'s JNC350R Series Power Modules, a new generation of isolated DC/DC converters, provide up to 350W output power in an industry-standard half-brick size footprint, making them ideal for high voltage and high power applications. The output is fully isolated from the input in these power converters from GE Energy (Formerly Lineage Power), which allows versatile polarity configurations and grounding connections. In addition, Lineage Power's JNC350R Series contains the optional Tunable Loop™ feature that lets users optimize the dynamic response of the converter to match the load with reduced amount of output capacitance, leading to savings on cost and the PWB area. Other features of the JNC350R Series include 2:1 input voltage range, threaded-through holes for easy mounting or the addition of a heat sink for high temperature applications, high power density (129 W/in3), low output ripple and noise, overtemperature protection auto restart, wide operating case temperature of -40ºC to 100ºC, no minimum load requirement, and more.

Tunable Loop™
The Tunable Loop™ feature allows the user to externally adjust the voltage control loop to match the filter network connected to the output of the module. Tunable Loop™ is achieved by connecting a series R-C between the SENSE (+) and TRIM pins of the module. (See the circuit diagram below.)
