Options
s Heat sinks available for extended operation
s Choice of primary remote on/off logic configura-
tions
s Delayed current-limit shutdown
Description
The JFC-Series 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 output is fully isolated from the input, allowing ver-
satile polarity configurations and grounding connec-
tions. The modules have maximum power ratings from
50 W to 100 W at typical full-load efficiencies of 85%.
The sealed modules have metal baseplates for excel-
lent thermal performance. Threaded-through holes
are provided for easy mounting or adding a heat sink
for high-temperature applications. Listed above are
the enhanced features for convenience and flexibility
s Small size: 61.0 mm x 57.9 mm x 12.7 mm
(2.40 in. x 2.28 in. x 0.50 in.)
