Description
These dual output converters are designed for ultra wide input
range low noise telecommunications, industrial, and instrument
applications. The very wide input range (4:1) is ideal for
battery or unregulated input applications while the low noise
complements even the most sensitive analog circuitry.
These converters are state of the art 220 kHz MOSFET
based designs that provide outstanding regulation and
conversion efficiencies of over 85%.
Remote ON/OFF and output voltage trim functions are also
included.
The converters are protected from output shorts to common
by a high speed pulse by pulse digital current limit circuit and
a self resetting thermal overload protection circuit.
As with all CALEX converters the 40 Watt XT Dual series
is covered by our 5 Year Warranty.
