DFC25 SERIES
SINGLE OUTPUT
DESCRIPTION
The DFC25 Series DC/DC converter provides tightly regulated
output voltages for industrial and datacom applications from 12, 24,
or 48 Volt inputs. Available output power ranges from 24.75 to 30
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 provide 1544 volts isolation from the input to output.
The input and output sections of the DFC25 Series are protected
from overvoltage transients via internal circuitry. Same voltage
models of the DFC25 family may be connected in parallel to
achieve additional output current.
