Reverse Current:
Accumulative
energy.
When the power supply is connected to a load
such as a battery, reverse current may flow back to
the power supply. To prevent damage to the
power supply, use a reverse-current-protection
diode in series between the power supply and
load.
Ensure the reverse withstand voltage of the diode is
able to withstand 2 times the rated output voltage of
the power supply and the forward current capacity can
withstand 3 to 10 times the rated output current of
the power supply.
Ensure the diode is able to withstand the heat
generated in the following scenarios.
When the diode is used to limit reverse voltage,
remote sensing cannot be used.
Grounding
The output terminals of the PSU power supplies are isolated with
respect to the protective grounding terminal. The insulation
capacity of the load, the load cables and other connected devices
must be taken into consideration when connected to the protective
ground or when floating.
As the output terminals are floating, the load and
all load cables must have an insulation capacity
that is greater than the isolation voltage of the
power supply.
