Item Value Definition
Reliability (MTBF) 135,000 hrs min. MTBF stands for Mean Time Between Failures, which is calculated according to the
probability of accidental 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 temper-
ature of 40°C and a load rate of 50%. Normally this is determined by the life expect-
ancy of the built-in aluminum electrolytic capacitor.

Operation
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:
S8T-BUS01 (DC line connected)
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.
•Not using parallel operation:
S8T-BUS02 (DC line not connected)
Mounting and Removing Bus Line Connectors
Pay attention to the following points to maintain electrical charac-
teristics.
•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 alter-
nately at both ends.
Wiring Linked Blocks
When linking Blocks together, wire input lines to one 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 rated current is exceeded, Bus Line Connectors may
be damaged.
When Basic Blocks are linked together, it is necessary to wire the
GR terminal of only one 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.

S8TS
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 voltages, set the same values for Blocks with V.ADJ
before linking them together. Adjust the set values within the limits
given in the following table.
Do not adjust voltages after Blocks are linked together. The out-
put voltage may become unstable.
Inrush Current
The inrush current per Basic Block is 25 A max. at 100 VAC and
50 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 at 100 VAC and
0.7 mA at 240 VAC. When N Blocks are linked together, the leak-
age 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 elements.

■Overload Protection
The Power Supply is provided with an overload protection func-
tion that protects the load and the power supply from possible
damage by overcurrent. When the output current rises above
105% min. of the rated current, the protection function is trig-
gered, decreasing the output voltage. When the output current
falls within the rated range, the overload protection function is
automatically cleared.
Note: Do not allow the short-circuited or overcurrent state to
continue for more than 20 s, otherwise internal elements
may deteriorate or be destroyed.
■Overvoltage Protection
The Power Supply is provided with an overvoltage protection
function that protects the load and the Power Supply from possi-
ble damage by overvoltage. When an excessive voltage is output,
the output voltage is shut OFF. Reset the Power Supply by turning
it OFF for at least 1 minute and then turning it back ON again.
24-V Models
12-V and 5-V Models
Note: Do not turn ON the power again until the cause of the ov-
ervoltage 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.
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 output termi-
nals. For accurate confirmation of the output status,
measure the voltage at the output terminal.
2. Transistor output:Open collector
30 VDC max., 50 mA max.
ON residual voltage: 2 V max.
OFF leakage current: 0.1 mA max.
3. The indicators become dimmer as the output voltage
approaches 0 V.
