Description
The FCO50A, FC100A, and FC150A Power Modules are dc-dc converters that operate over an input voltage range of 18 Vdc to 36 Vdc and provide a precisely regulated dc output. The outputs are fully isolated from the inputs, allowing versatile polarity configurations and grounding connections. The modules have maximum power ratings from 50 W to 150 W at a typical full-load efficiency of 81%. Built-in filtering, for both the input and output of each device, eliminates the need for external filters. Two or more modules may be paralleled with forced load sharing for redundant or enhanced power applications. The Package, which mounts on a printed-circuit board, accommodates a heat sink for high-temperature applications. * ULis a registered trademark of Underwriters Laboratories, Inc. + CSAis a ragistered trademark of Canadian Standards Association, + TOVis a registered trademark of Technischer Uberwachungs-Verein. @™! 00500eb 0033279 7b4 mm

Table 1. Input Specifications CAUTION: This power module is not internally fused. An input line fuse must always be used. safety agencies require a normal-blow, de fuse with a maximum rating of 15 A (see Safety Considerations section). type of fuse with a lower rating can be used. Refer to the fuse manufacturer's data for further information.
