PART NUMBER: VHK100W
DESCRIPTION: chassis mount dc-dc converter
description
features
The VHK100W series of rugged DC-DC
converters are designed for high
·66-100W isolated output
·Efficiency to 87%
·RoHS Compliant
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
·4:1 input range
·Regulated output
·Continuous short circuit
protection
·Metal enclosure with integrated
heatsink
·Rugged design
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.
·Over-temperature shutdown
