2.3.3
In case of load with accumulated energy, such as
batteries
When a load, such as a battery, that contains accumulated energy, is connected, the
load can send a large current to the capacitor inside the power supply via the
protective diode on the output control circuit inside the power supply. Such currents
may damage the internal components of the power supply, and reduce the life of the
load.
To handle this type of load, connect in series a diode (D
RP
) between the power supply
and the load for reverse-current prevention.
CAUTION
•
To protect the power supply and the load, select D
RP
that meets
the following requirements:
1. Reverse-voltage tolerance is at least two times the rated
output voltage of the power supply.
2. Forward current capacity is three to ten times the rated
output current of the power supply.
3. A diode with small loss
•
Be sure to take account of heat generation from D
RP
. D
RP
may
burn unless adequately dissipated.
•
The remote sensing function cannot be used when the D
RP
is
connected.
