Specifications
■Ratings/Characteristics
12/24-V Models (Basic Block: S8TS-06024@/S8TS-03012@)
Note: 1. Do not use an inverter output for the Power Supply. Inverters with an output frequency of 50/60 Hz are available, but the rise in the internal
temperature of the Power Supply may result in ignition or burning.
2. Refer to page 7 for details on adjusting the output voltage for parallel operation. If set to less than −10%, the undervoltage detection function may
operate. Ensure that the output capacity and output current after adjustment do not exceed the rated output capacity and rated output current
respectively. Adjusting V.ADV may cause the output voltage to exceed the voltage range. When adjusting the output voltage, confirm the actual
output voltage from the Power Supply and be sure that the load is not damaged.
3. Class 2 approval does not apply to parallel operation.
4. The output current is specified at power output terminals.
5. Refer to the Engineering Data on page 8 for details.
6. To reset the protection, turn OFF the input power for one minute or longer and then turn it back again.
7. Be sure to mount End Plates (PFP-M) on both ends of the Power Supply.
8. The range for compliance with EC Directives and safety standards (UL, EN, etc.) is 100 to 240 VAC (85 to 264 VAC).
9. The noise level depends on the wiring method and other factors. Insert one clamp filter (the ZCAT2436-1330A from TDK) as a noise
countermeasure on the input line and ground line combined.

Item Value Definition
Reliability (MTBF) 250,000 hrs min. MTBF stands for Mean Time Between Failures, which is calculated according to the probability of acci-
dental device failures, and indicates reliability of devices. Therefore, it does not necessarily represent the
life of the product.
Life expectancy 10 yrs min. The life expectancy indicates average operating hours under the ambient temperature of 40°C and a load
rate of 50%. Normally this is determined by the life expectancy of the built-in aluminum electrolytic ca-
pacitor.

■Application Methods
Increasing Output Capacity
Example for 24-V Models
Configuring Multiple Outputs
Maximum Number of Blocks That Can
Be Linked
Basic Blocks can be linked using Bus Line Connectors.
Increasing Output Capacity
N+1 Redundant Systems
To ensure stable operation when there is a failure in one of the
Blocks, use within the derating curve for N+1 redundant systems.
Multi-output Power Supply
Up to 4 Basic Blocks with different output voltage specifications can
be linked.
Selecting Bus Line Connectors
Select Bus Line Connectors according to the linking method as
follows:
Using Parallel Operation
Use the S8T-BUS01 (DC line connected). (See Figure 1.)
The S8T-BUS01 Bus Line Connector is equipped with a selector to
prevent erroneous connection of Blocks with different output voltage
specifications. Slide the selector to the output voltage for parallel
operation.
Note: Parallel operation is enabled by using a current balance
function. For the current balance function to operate, the S8T-
BUS01 must be used.
Not Using Parallel Operation
Use the S8T-BUS02 (DC line not connected). (See Figure 2.)

Mounting and Removing Bus Line
Connectors
Pay attention to the following points to maintain electrical
characteristics.
Do not insert/remove the Connectors more than 20 times.
Do not touch the Connector terminals.
To remove the Connectors, insert a flat-bladed screwdriver
alternately at both ends.
Wiring Linked Blocks
When linking Blocks together, wire input lines to one Basic Block
only, otherwise inputs may be shorted internally resulting in damage
to the Block.
Do not cross-wire Blocks or wire between a Block and another
device. If the current exceeds the rated current, Bus Line Connectors
may be damaged.
When Basic Blocks are linked together, it is necessary to wire the PE
terminal of only one Basic Block, not all the Blocks.
Series Operation and ± Output
Using 2 Basic Blocks enables series operation and the use of
±output. An external diode is not required for S8TS-06024@ and
S8TS-03012@ models, but is required for S8TS-02505@ models.
Use the following as a rough guide for selecting the diode.
Note: Series operation is possible with different specifications, but the
current that flows to the load must not exceed the rated output
current of any Block.
Adjusting Output Voltage for Parallel
Operation
The Blocks are factory-set to the rated output voltage. When
adjusting output voltages, set the same values for Blocks with output
voltage adjuster (V.ADJ) before linking them together. Adjust the set
values within the limits given in the following table.
Do not adjust output voltages after Blocks are linked together. The
output voltage may become unstable.
Inrush Current
The inrush current per Basic Block is 17.5 A max. at 100 VAC and
35 A max. at 200 VAC. When N Blocks are linked together, the inrush
current will be equal to N times that for 1 Basic Block. Be sure to use
a fuse with the appropriate fusing characteristics or a breaker with
the appropriate tripping characteristics.
Leakage Current
The leakage current per Basic Block is 0.35 mA max. at 100 VAC
and 0.7 mA max. at 240 VAC. When N Blocks are linked together,
the leakage current will be equal to N times that for 1 Basic Block.
Mounting
Mounting Direction
Use standard mounting only. Using any other mounting method will
prevent proper hear dissipation and may result in deterioration or
damage of internal parts.

Engineering Data
■Derating Curves
Note: 1. If there is a derating problem, use forced air-cooling.
2. The ambient temperature is specified for a point 50 mm below the Power Supply.
3. Use the rated output for single operation multiplied by N as a reference for the load ratio for an N+1 redundant system.
4. DC Input: If the input voltage is less than 100 VDC, reduce the load to 0.8 or less times the values given in the above derating curves.
■Overload Protection
The Power Supply is provided with an overload protection function
that protects the Power Supply from possible damage by overcurrent.
When the output current rises above 105% min. of the rated current
(100% min. of the rated current for parallel operation), the protection
function is triggered, automatically decreasing the output voltage.
When the output current falls within the rated range, the overload
protection function is automatically cleared.
The values shown in the above diagram are for reference only.
Note: Internal parts may occasionally deteriorate or damaged if a
short-circuited or overcurrent continues for 20 min. or longer.
■Overvoltage Protection
An overvoltage protection function is provided so that excessive
voltage is not applied to the load, e.g., if the feedback circuit in the
Power Supply fails. When a voltage that is approximately 120% of the
rated voltage or more is output, the output voltage is shut OFF. Reset
the input power by turning it OFF for at least 1 minute and then
turning it back ON again.
12-V and 5-V Models
24-V Models
The values shown in the above diagrams are for reference only.
Note: Do not turn ON the input power again until the cause of the
overvoltage has been removed.

■Undervoltage Indicator and
Undervoltage Detection Output
When a drop in the output voltage is detected, the red indicator (DC
LOW) lights and transistor (DC LOW: OUT) output turns ON to
provide external notification of the error. The detection voltage is set
to approximately 80% (75% to 90%) of the rated output voltage.
Note: 1. This function monitors the voltage at the power output
terminals. For accurate confirmation of the output status,

N+1 Redundancy S8TS Operation
No special settings are required for N+1 redundant operation
with the S8TS. Just link Basic Blocks for redundant operation
in parallel to enable N+1 redundant operation.
A current balance function is used for S8TS N+1 redundant
operation so that each Block provides the same current. If one
Power Supply fails, the remaining Power Supplies share the
load of the failed Power Supply, and operation continues with
each Power Supply providing more current.
The Power Supply that has failed can be identified by the
output indicator, undervoltage indicator, and undervoltage
detection output to enable replacing the Block with a normal
Block. Always turn OFF the input power before replacing a
Block. To increase Power Supply reliability, use only 90% or
less of the maximum rated capacity for N Power Supplies
even when N+1 Power Supplies are linked.
In an N+1 redundant system, N
Power Supplies of the same
model are linked in parallel
connections and one additional
Power Supply of the same
model is added for redundancy.
(N is 1 for a single operation
system.) This setup increases
system reliability.

Safety Precautions
Refer to Safety Precautions for All Power Supplies.
!CAUTION
■Precautions for Safe Use
Mounting
Heat dissipation capacity may be decreased if a non-standard mounting
method is used, occasionally resulting in damage to internal components.
Use only the standard mounting method.
To improve the long-term reliability of devices, give due consideration
to heat dissipation when mounting. With the S8TS, heat is dissipated
by natural convection. Mount Blocks in a way that allows convection
in the atmosphere around them.
Do not allow cuttings to enter the Power Supply during installation
work.
Be sure to remove the sheet covering the Power Supply for
machining before turning ON the power so that it does not interfere
with heat dissipation.
*1. Convection of air
*2. 75 mm min.
*3. 75 mm min.
*4. 10 mm min.
When cutting out holes for mounting, make sure that cuttings do not
enter the interior of the products.
Wiring
Ground the product completely. Failure to do so could cause the
electric shock or malfunction.
Ensure that input and output terminals are wired correctly.
Use the following material to the wire to be applied to the product for
preventing from the occurrence of the smoking or ignition caused by
the abnormal load.
Recommended Wire Type:(For Single unit operation)
Do not apply more than 100-N force to the terminal block when
tightening it.
Use the following material for the wires to be connected to the S8TS
to prevent smoking or ignition caused by abnormal loads.
Recommended Wire Size for Single-unit
Operation
Recommended Wire Size for Parallel
Operation
Blocks with Connector Terminals
When using Blocks with connector terminals, the current for
1 terminal must not exceed 7.5 A. If a higher current is required, use
2 terminals.
Do not insert/remove AC input connectors or DC output connector
more than 20 times.
Installation Environment
Do not use the Power Supply in locations subject to shocks or
vibrations. In particular, install the Power Supply as far as possible
from contactors or other devices that are a vibration source. Be sure
to mount End Plates (PFP-M) on both ends of the Power Supply.
Install the Power Supply well away from any sources of strong, high-
frequency noise and surge.
•Do not disassemble the product or touch internal parts
during power-on. Electric shock may be caused.
•Do not touch the product during power-on, and
immediately after poweroff. Hot surface may cause
heat injury.
•Electrical shock or minor injury may occasionally occur.
Do not touch the terminals while power is being
supplied. Also, always attach the Terminal Cover after
you complete wiring.
While power is supplied, voltages up to 370 V are
generated internally. The voltage can remain for 30
seconds after the power supply is turned OFF.
•Do not remove any connector cover unless using bus
line connectors. Electric shock may be caused.
•Tighten the terminal screws with torque: 9.6 in-lb
(1.08N·m), and tighten the connector screw and screw
flange with torque: 2.7 in-lb (0.3N·m). Loose screws
may cause fire.
•Minor injury, fire, or device failure may occasionally
occur. Do not allow any pieces of metal, conductors, or
cuttings from installation work to enter the Power
Supply.

Ambient Operating and Storage
Environments
Do not use or store the Power Supply in the following locations.
Doing so may result in failure, malfunction, or deterioration of
performance characteristics.
Do not use the Power Supply in locations subject to direct sunlight.
Do not use the Power Supply in locations where the ambient
temperature exceeds the range of the derating curve.
Do not use the Power Supply in locations where the humidity is
outside the range 25% to 85%, or locations subject to condensation
due to sudden temperature changes.
Do not store the Power Supply in locations where the ambient
temperature is outside the range –25 to 65°C or where the humidity
is outside the range 25% to 95%.
Do not use the Power Supply in locations where liquids, foreign
matter, corrosive gases, or corrosive gases may enter the interior of
the Power Supply.
Short-circuits or overcurrent conditions that last for 20 seconds or
longer may cause deterioration or damage to internal parts.
Output Voltage Adjuster (V.ADJ)
Do not exert excessive force on the output voltage adjuster (V.ADJ).
Doing so may break the adjuster.
Setting the output voltage adjuster (V.ADJ) to 90% or less of the
rated output voltage may cause the undervoltage detection function
to operate.
Bus Line Connectors
Do not apply strong shocks (e.g., by dropping) to the Bus Line
Connectors. Doing so may result in damage.
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).
To dismount the Block, pull down portion (C) with a flat-blade
screwdriver and pull out the Block.
In Case There Is No Output Voltage
If there is no output voltage, it is possible that overload protection or
overvoltage protection is operating. It is also possible that the latch
protection circuit is operating due to the application of a large surge,
such as lightning surge. Confirm the 2 points below. If there is still no
output voltage, consult your OMRON representative.
•Checking for Overload Protection:
Separate the load line and confirm that it is not in an overload state
(including short-circuits).
•Checking for Overvoltage Protection or Latch Protection:
Turn the input power OFF, and then turn it ON again after 1 minute
or more has elapsed.
Buzzing Noise When the Input Is
Turned ON
A harmonic current suppression circuit is built into the input power.
This circuit can create noise when the input is turned ON, but it will
last only until the internal operation stabilizes and does not indicate
any problem in the Power Supply.
