Connecting the Load
trol circuit, and depending on the situation, the product may
burn out or the load's working life may be reduced.
For any such load, connect a reverse current protection diode
D
RP in series between the PMC-A and the load, as shown in
Fig. 3-4 "Remedy against load with accumulated energy".

energy
• To protect the load and the PMC-A, select DRP
according to the following criteria.
Reverse voltage withstand capacity: At least twice
the rated output voltage of the power supply.
Forward current capacity: Three to ten times the
rated output current of the power supply.
A diode with small loss.
•Be sure to take into account the heat generated by
D
RP. DRP may burn out if heat dissipation is inade-
quate.
3.2 Connecting the Load
This section describes the wire used to connect the PMC-A to
the load, and the connection to the output terminal.
• Before connecting to the load, confirm that the
POWER switch is turned on, and that the OUTPUT
is turned off.
