current may flow into the power supply. To prevent damage to the power supply,
connect a reverse protection diode in series between the power supply and the
load.
Note
Ensure that the reverse voltage of the protection diode
can withstand 2 times the rated output voltage of the
power supply and that it can withstand 3 ~ 10 times of
the rated output current of the power supply in forward
(conduction) current.
Ensure that the diode can withstand the subsequent
heat generated by the maximum power that the supply
can deliver.
When a diode is used to limit the reverse voltage, the
remote measurement function should be turned off
Grounding
The output terminals of the power supplies are independent of the protective
ground terminal. When in protective grounding or floating low, the insulation
capacity of the load, load line, and other connected equipment must be
considered.
Floating
When the output terminal is floating, the load and all load wires must be
insulated, and the insulation capacity should be greater than the insulation
