The VKA60xS Series DC/DC

converters present an economical and

practical solution for distributed

power system architectures which

require high power density and

efficiency while maintaining system

modularity and upgradeability. With

the ability to operate over a wide

input voltage range of 18 to 36 and

33 to 75 volts, these modules are

ideal for use in battery backup

applications common in todays'

telecommunication and electronic

data processing applications. The

output is fully isolated from the

input, allowing for a variety of

polarity and grounding configura-

tions.

The VKA60xS's proprietary

control circuitry responds to 50-100%

load steps in 100

µSeconds to within

1% nominal Vout.

The patented fixed frequency

architecture combined with surface

mount technology results in a com-

pact, efficient and reliable solution to

DC/DC conversion requirements.

Safety per UL1950, EN 60950 and

CSA 22.2 #234
