capacity of the power supply or load.
Reverse current connection method
When the power supplies are connected to a load such as a battery, reverse 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 voltage of the power supply.
