50 to 60 XW Single Series DC/DC Converters
Features
!
Description
These single output converters are designed for wide input
range low noise telecommunications, industrial, and
instrument applications. The wide input range (2:1) 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 with efficiencies exceeding 85%.
The single outputs are regulated by a high loop gain current
mode control method that provides linear regulator type
performance with a true, high efficiency switching DC/DC
topology. The large amount of loop gain also insures excellent
input ripple rejection and line transient response. Remote
output voltage sense, output voltage trim and ON/OFF
functions are also included.
They 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. The input
and output are overvoltage protected with 1500W transient
suppressor diodes for zero failure rate operation.
As with all CALEX converters the 50/60 Watt XW Single
Series is covered by our standard 5 Year Warranty.
