Description
These single 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 line and load regulation
and efficiencies exceeding 80%.
Remote output voltage sense, output voltage trim and ON/
OFF 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 45 watt XT Single series
is covered by our 5 Year Warranty.
