description

The VHK100W series of rugged DC-DC

converters are designed for high

reliability applications, featuring integral

heat sink, over-temperature protection,

over-current protection and input

transient voltage protection. With an

external input fuse, the converter can

protect accidental input polarity reversal.

The wide 4:1 input range (10-36V or 18-

75V) is very useful to stabilize an input

source like batteries in various

discharging and charging conditions.

Additionally, high efficiency, fast

response, tight regulations, remote sense

and remote On/Off control make these

converters very useful in many industrial

and communications applications.

notes:

1. see output derating curves (page 4)

2. input currents are measured at nominal input voltage

3. efficiency is measured at nominal line, full load
