Load Considerations
Loads with accumulated energy
Connecting a load with accumulated energy, such as a battery, to the PWX series may cause
current to flow from the load to the internal circuit of the PWX series. This current may dam-
age the PWX series or reduce the life of the load.
For this type of load, connect a reverse-current-prevention diode (D
RP
) between the PWX
series and the load in series as shown in the following figure.
This cannot be used in conjunction with remote sensing.

RP
CAUTION
• To protect the load and the PWX series, use a D
RP
that conforms to the following
specifications.
Reverse voltage withstand capacity:
At least twice the rated output voltage of the PWX series.
Forward current capacity:
Three to ten times the rated output current of the PWX series
.
A diode with small loss.
• Be sure to take into account the heat generated by D
RP
. D
RP
will burn out with inadequate
heat dissipation.
