Load Considerations
Note that the output will become unstable if the following types of loads are connected.
Load with accumulated energy
Connecting a load with accumulated energy, such as a battery, to
the PWR may cause current to flow from the load to the internal cir-
cuit of the PWR. This current may damage the PWR or degrade the
service life of the load.
For this type of loads, connect a reverse-current-prevention diode
(DRP) between the PWR and the load in series.
CAUTION
• To protect the load and the PWR, select a DRP that com-
plies with the following conditions.
Reverse voltage withstand capacity of at least twice the
rated output voltage of the PWR.
Forward current capacity that is 3 to 10 times the rated out-
put current of the PWR.
A diode with small loss.
• Be sure to take into account the heat generated by DRP.
DRP may burn out without adequate heat dissipation.

Cannot be used in combination with remote sensing.
