eSure™ Converter
C400/48-3500e
Key Features
3500 Watt high-efficiency
converter designed to operate
from a nominal 400V DC source
to provide -48V DC load power
Optimized depth –
reduced footprint allows
installation in short-depth
racks and cabinets
DSP (Digital Signaling
Processor) – means fewer
components, optimized
operation and active load
sharing for increased reliability
In addition to reducing power consumption and
lowering operating cost, eSure™ high-efficiency
converters offer superior performance and
uncompromised reliability.
Description
The eSure™ C400/48-3500e high-efficiency converter is designed to operate from a
nominal 400V DC source to provide nominal -48V DC load power, which is adjustable
to application needs. The C400/48-3500e is a constant power converter designed
with the latest patented switchmode technology, using DSP (Digital Signaling Processor)
functionality for efficient operation.
For a higher load capacity, converters can be connected in parallel, and intelligent
control can be added with the help of a separate controller.
Compliant with global
standards – delivers quality,
performance and reliability no
matter what the application or
location demands
High efficiency over 97% – reduces
power consumption for lower
operating costs
Hot pluggable – facilitates
future extensions
