Description
The DFC25 Series dc-dc converter provides three output voltages from a single 12,
24, or 48 volt nominal input for industrial and datacom equipment. Available output
power ranges up to 25 watts. Excellent noise performance is attained via an
aluminum case, toroidal magnetics, and double shielded transformers. Common
mode and differential mode input filtering is integral to the design. Selected models
provides 1544 volts isolation from input to output.
The input and output sections of the DFC25 Series are protected from overvoltage
transients via internal circuitry. Same voltage single output units of the DFC25
family may be connected in parallel to achieve additional output current.
