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 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 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 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.

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 output
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 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 elements.

Engineering Data

■ Derating Curves

Note: If there is a derating problem, use forced air-cooling.

The ambient temperature is specified for a point 50 mm below the power supply.

■ Overload Protection

The Power Supply is provided with an overload protection function
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 (100% min. of the rated current for parallel operation),
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.

Note: Do not allow the short-circuited or overcurrent state to continue

for more than 20 s, otherwise it may damage the element.

■ Overvoltage Protection

The Power Supply is provided with an overvoltage protection function
that protects the load and the Power Supply from possible 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 overvolt-

age has been removed.

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.

This function monitors the voltage at the output terminals. For accu­rate confirmation of the output status, measure the voltage at the
output terminal.

Precautions

!WARNING

Do not attempt to take any Block apart or touch the interior of a
Block while the power is being supplied. Doing so may result in
electric shock.

Do not link or separate any Blocks while the power is being sup­plied. Doing so may result in electric shock.

Do not remove the connector cover on unused Bus Line Connec­tors. Doing so may result in electric shock.

Close the terminal covers before use. Not doing so may result in
electric shock.

!Caution

When linking Blocks, lock the sliders and track stoppers.

When linking Blocks, wire the input line for 1 Block only. Other­wise, inputs may be shorted internally resulting in damage to the
Blocks.

The tightening torque for terminal screws is 1.08 N·m. The tighten­ing torque for connector screws and screw flanges is 0.30 N·m.
Loose screws may result in fire.

Do not touch the Power Supply while power is supplied or imme­diately after power is turned OFF. The Power Supply becomes hot
and touching it may result in injury.

Mounting

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.

*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

Be sure to wire I/O terminals correctly. When tightening the termi­nals, do not exert a force of 100 N or more on terminal blocks or con­nector terminals.

With Blocks with connector terminals, the current for 1 terminal must
not exceed 7.5 A. If a higher current is required, use 2 terminals.

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. 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.

Supplies

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 in locations subject to direct sunlight.

• Do not use in locations where the ambient temperature exceeds

the range of the derating curve.

• Do not use 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 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 in locations where liquids, foreign matter, corrosive

gases, or flammable gases may enter the interior of products.

Charging Batteries

If a battery is connected as the load, provide an overcurrent control
circuit and an overvoltage protective circuit.

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 adjuster to a setting less than 10% may cause the under­voltage detection function to operate.

Bus Line Connectors

Do not apply sudden shocks (e.g., by dropping) to the Bus Line Con­nectors. Doing so may result in damage.

DIN Track Mounting

To mount the Block on a DIN track, hook portion (A) of the Block onto
the track 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.

No Output Voltage

If there is no output voltage, it is possible that overcurrent 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 Overcurrent Protection:

Separate the load line and confirm that it is not in an overcurrent
state (including short-circuits).

• Checking for Overvoltage Protection or Latch Protection:

Turn the input power supply OFF, and then turn it ON again after 1
minute or more has elapsed.
