1 / 11 page rev. page date page date DESCRIPTION: chassis mount dc-dc converter 1 of 11 08/2009 20050 SW 112th Ave. Tualatin, Oregon 97062 phone phone 503.612.2300 fax www.v-infinity.com fax 503.612.2383 PART NUMBER: VHK50W features ·25-50W isolated output ·Efficiency to 83% ·RoHS Compliant ·4:1 input range ·Regulated output ·Continuous short circuit protection ·Metal enclosure with integrated heatsink ·Rugged design ·Over-temperature shutdown description The VHK50W 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 (9-36V 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.
