PWR-01 19
Installation and Preparation ｜ Load Considerations
Loads with accumulated energy
Connecting a load with accumulated energy, such as a battery, to the PWR-01 may cause
current to flow from the load to the internal circuit of the PWR-01. This current may damage
the PWR-01 or reduce the life of the load.
For this type of load, connect a reverse-current-prevention diode (DRP) between the PWR-01
and the load in series as shown in the following figure.
This cannot be used in conjunction with remote sensing.
Load with accumulated energy
DRP: Reverse-current-protection diode
• To protect the load and the PWR-01, use a DRP that conforms to the following
specifications.
Reverse voltage withstand capacity: At least twice the rated output voltage of the PWR-01.
Forward current capacity: 3 to 10 times the rated output current of the PWR-01.
A diode with small loss.
• Be sure to take into account the heat generated by D
RP. DRP will burn out with inadequate
heat dissipation.
