Din Rail Mounting; Series Operation; Parallel Operation - Omron S8VS - MODEL 15-30-60-90-120-180-240W Manual

DIN Rail Mounting

To mount the Block on a DIN rail, hook portion (A) of the Block onto
the rail and press the Block in direction (B).

Series Operation

(24-V Model)
Two power supplies can be connected in series.
The (±) voltage output can be accomplished with two power supplies.

Note: 1. The diode is connected as shown in the figure. 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.
3. Serial operation is not possible with 5-V and 12-V Models.

Parallel Operation

The product is not designed for parallel operation.

In Case There Is No Output Voltage
The possible cause for no output voltage may be that the overcurrent
or overvoltage protection has operated. The internal protection may
operate if a large amount of surge voltage such as a lightening surge
occurs while turning ON the power supply.
In case there is no output voltage, please check the following points
before contacting us:
• Checking overload protected status:
Check whether the load is in overload status or is short-circuited.
Remove wires to load when checking.
• Checking overvoltage or internal protection (except for 15-W
Models):
Turn the power supply OFF once, and leave it OFF for at least 3
minutes. Then turn it ON again to see if this clears the condition.
Harmonic Current Suppression
Circuits
(120-W, 180-W and 240-W Models)
A harmonic current suppression circuit is built into the Power Supply.
This circuit can create noise when the input is turned ON, but it will
last only until the internal circuits stabilize and does not indicate any
problem in the product.
