d
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".

•
To protect the load and the PMC-A, select D
RP
according to the following criteria.
Reverse voltage withstand capacity: At least twice
the rated o
u
tp
u
t voltage of the power s
u
pply.
Forward c
u
rrent capacity: Three to ten times the
rated o
u
tp
u
t c
u
rrent of the power s
u
pply.
A diode with small loss.
• Be s

nt the heat generated by
D
RP
. D
RP
may b

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
PO
W
ER switch is t
u
rned on, and that the OUTPUT
is t
u
rned off.
