2.4.3 In case of load with accumulated energy, such
as batteries
Connecting a load with accumulated energy, such as a battery, to the
output of the unit may cause a large current to
fl ow from the load
through the internal output control circuit protection diode to the
internal capacitor. Such currents may damage the internal compo-
nents of the unit, and reduce the life of the load.
As a remedy, connect a reverse-current-prevention diode D between
the unit and the load as shown in Fig.2-4. In this case, however, the
unit cannot be used in combination with remote sensing units.
Fig.2-4 Measures against load with accumulated
energy
• To protect the unit and the load, select the reverse-
current-prevention diode D according to the following
standard.
1. Reverse voltage withstand capacity: Minimum of
twice the rated output voltage of the unit.
2. Forward current capacity: Three to ten times the
rated output current of the unit.
3. A diode with small loss
• Be sure to take account of heat generation from the
diode D. The diode may burn unless adequately dis-
sipated.
