Description
The PerkinElmer Optoelectronics DC-DC
Converters, available in 1, 2 and 3 output
configurations, offer military electronics
designers outstanding flexibility in DC
power distribution. The converters are
small and lightweight, facilitating decen-
tralized packaging. They can be PC-Board
mounted near the load or installed in a
centrally located, multiple output power
supply. Their high-efficiency operation
conserves power and simplifies thermal
design, while delivering tightly regulated
DC power under dynamic line and load
conditions. Additional tailoring can be
achieved through N+1 redundancy,
paralleling and external synchronization.
