These robust DC input
battery chargers have a wide operating temperature range, and use a DIN
terminal block for input and output connections. The wide input voltage range
allows use in 12V vehicle systems, and designed to allow the use of 48 volt
equipment in 12 volt, vehicles, marine, military, PLC, and cell tower
applications. These are attractive, reliable, robust DC/DC chargers good for
fork lifts, off-road, construction and recreational equipment. They are
relatively immune to vibration and shock.
To determine the output amps
you need just add up the watts of all the equipment and divide by 48V.
These converters have common negative ground (non-isolated) and can be
used for common ground and floating ground installations.
