ComPAC
Product Highlights
™
DC-DC Switchers
50 to 600W
1-3 Outputs
ComPAC meets Bellcore, British
Telecom and IEC specifications for
transient protection; Bellcore, British
Telecom and FCC/VDE specifications
for EMI/RFI; and benefits from the
proven field performance, high
efficiency and inherent high reliability
of our VI-200 component-level power
converters. With input voltage ranges
optimized for industrial and
telecommunication applications,
ComPAC provides extended input
overvoltage capability, input reverse
polarity protection, undervoltage
lockout, and master disable. In a
package just .99" (25,2mm) in height,
ComPAC delivers up to 600W
from one, two or three outputs of
1 to 95Vdc.
Use the configuration chart at the right to define your
Vicor part number(s).
