Description
The “Cool Power Technologies” CP30_1790018 DC-DC converter is an open frame isolated 1” X 1” DC-
DC module that conforms to industry standard pinout and trim equations. The converter operates over
an input voltage range of 9 to 36 VDC, and provides a tightly regulated output voltage with an output
current rating of 9 A. The output is fully isolated from the input and the converter meets Basic
Insulation requirements with 2250VDC I/O isolation rating open frame, 1600VDC for the encapsulated
version. The standard feature set includes remote On/Off (positive or negative enable), input
undervoltage lockout, output overvoltage protection, overcurrent and short circuit protections, output
voltage trim and overtemperature shutdown with hysteresis. The high efficiency of the CP30_1790018
allows operation over a wide ambient temperature range with minimal derating.
