Description
The 2000W high-efficiency eSure™ solar MPPT converter ( model S48-2000e3) is designed to
convert solar DC supply voltages into nominal -48 V DC voltage that is adjustable to
application needs. The S48-2000e3 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.
Very high power density, occupies
minimum space
Wide input voltage range (120VDC
to 420VDC) allows for a wide range
of solar panel configurations
Hot pluggable – facilitates
future expansions and easy
maintenance
