(5-V OUTPUT MODELS ONLY)
Natural air-cooling
Models with a power rating of 10 or 15 W incorporate a Zener
diode clamp circuit. If the protection circuit is triggered, contact
your OMRON representative for repairs.
Models with a power rating of 25 or 50 W incorporate a shut-off
circuit. If the protection circuit is triggered, turn off the input power
and leave the power supply off for at least one minute before
turning it on again.

INRUSH CURRENT, RISE TIME AND-
OVERLOAD PROTECTION
The power supply has an overload protection function that
protects the load and the power supply from possible
damage by overcurrent. When the output current rises above
a set value (105% of the rated output current), the protection
function is triggered, decreasing the output voltage. When
the output current falls within the rated range, the overload
protection function is automatically cleared.

GENERATING OUTPUT VOLTAGE (±)
An output of ± can be generated by using two power supplies
as shown below, because the power supply produces a
floating output.
If operation amplifiers as loads are connected in series,
connect a diode between the positive and negative output
terminals of each power supplies as shown in the illustration
below. Consult your OMRON representative for the
specifications of the diode. No diode is necessary for models
with power ratings of 50 W.

Precautions
MOUNTING
•
•
Open-Frame and Covered-Type
Mount the power supply so that air flow takes place around it.
To improve and maintain the reliability, the power supply is
designed to dissipate heat by using natural air flow.
Mounting the power supply to a metal plate is recommended.
Two or More Power Supplies Side-by-Side
•
•
When mounting two or more power supplies side by side,
allow at least 20 mm (0.79 in) spacing between them, as
shown in the following illustration.
Forced-air cooling is recommended.
(A). Side mounting
(B). Bottom mounting (secured with screws from the inside of the
power supply)
Note: This method is not possible with the covered-type.
(C). Back mounting (secured with screws from the back of the
power supply)
