The SMFL Series™ 28-volt DC/DC converters are rated up to 65 watts output power over a -55° to +125°C temperature range with a 28 Vdc nominal input. On dual output models up to 70% of the rated output power can be drawn from either the positive or negative outputs. Current sharing allows the units to be paralleled for total power of up to 148 watts. The welded, hermetically sealed package is only 3.0 x 1.5 x 0.40 www.DataSheet4U.com inches, giving the series an overall power density of up to 45 watts per cubic inch.
