PART NUMBER:
VHK200W
DESCRIPTION:
chassis mount dc-dc converter
description
The VHK200W 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.
