Output Voltage Adjuster (V.ADJ)
• The output voltage adjuster (V.ADJ) may possibly be damaged if it
is turned with unnecessary force. Do not turn the adjuster with
excessive force.
• After completing output voltage adjustment, be sure that the output
capacity or output current does not exceed the rated output
capacity or rated output current.
Ripple Noise Voltage
(S8JX-G Series 300 W 5 V and 600 W 5 V or 12 V
Models)
The specified standard for the ripple voltage noise was measured with
a measurement circuit that is based on JEITA standard RC-9131A.

DIN Rail-mounting
To mount the Power Supply to a DIN
Rail, pull down the rail stopper until
you hear it clicks open, hook portion
(A) of the Power Supply onto the DIN
Rail, press the Power Supply in
direction (B), and then push up the rail
stopper to lock the Power Supply in
place.
To dismount the Power Supply, pull
down portion (C) with a flat-blade
screwdriver and pull out the Power
Supply.
Series Operation
Two power supplies can be connected in series. The (±) voltage
output can be accomplished with two Power Supplies.

Note: 1. If the load is short-circuited, a reverse voltage will be
generated inside the Power Supply. If this occurs the Power
Supply may possibly deteriorate or be damaged. Always
connect a diode as shown in the figure. Select a diode
having the following ratings.

2. Although Products having different specifications can be
connected in series, the current flowing through the load
must not exceed the smaller rated output current.

Parallel operation is possible under 80% of the rated value.
• To operate in parallel, set the switch to the "PARALLEL" side.
• The length and thickness of each wire connected to the load must
be the same so that there is no difference in voltage drop value
between the load and the output terminals of each Power Supply.
• It is desirable to set the same value on the voltage adjuster of each
Power Supply.
