Specifications

■ Ratings/Characteristics

Note:1. When a load is connected that has a built-in DC-DC converter, the overload protection may operate at startup and the power supply may not start.

Refer to the Overload Protection section on page 8 for details.

2. Use with DC voltage input is beyond the conditions of approval or conformance to applicable safety standards. (DC input possible with 15 W max.
Use the 7.5-W single-output models under the load of 90% max. if the voltage range is between 90 and 110 VDC.
Do not use the 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.

3. Defined with a 100% load and the rated input voltage (100 or 200 VAC.)

4. The output specification is defined at the power supply output terminals.

5. If the V. ADJ adjuster is turned, the voltage will increase by more than +10% of the voltage adjustment range. (+15% for S82K-03012/-03024)

When adjusting the output voltage, confirm the actual output voltage from the Power Supply and be sure that the load is not damaged.

6. The settings for the output voltage must be within the following range:
+V: ±1% of the rated value

−V: ±5% of the rated value

7. Refer to the Overload Protection section on page 8 for details.

8. When using the 7.5-W single-output models within the input voltage range between 90 and 110 VDC, the protection function will operate at a current of 95% to

160% of the rated load current.

8 Switch Mode Power Supply S82K

■ 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, 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.

Note: 1. When connecting a load that has a built-in DC-DC converter, the overcurrent protection function may operate during start-up, thus pre-

venting the Power Supply from starting.

2. Internal parts may occasionally deteriorate or be damaged if a short-circuited or other overcurrent state continues during operation.

3. When using the 7.5-W single-output models within the input voltage range between 90 and 110 VDC, the overload protection function

will operate at currents from 95% to 160% of the rated output current.

4. When using the 90-W model at an ambient temperature of 25

°C or less, the overload protection function will operate at currents from

101% to 111% of the rated output current. When using the 90-W model at an ambient temperature exceeding 25

°C, the overload protec-

tion function will operate at currents from 92% to 111% of the rated output current.

5. When using the 100-W model with PFC in parallel operation, operation is limited to a load ratio of 90% to 100% of the rated output current
at 4.2 A.

When Using ± Output Models

The +V output detects the total output power (+V output and −V output) to trigger the short-circuit protection against overcurrent. This protection
varies depending on the

−V output state. The −V output independently triggers the short-circuit protection.

■ Undervoltage Alarm Indicator and Output Function

If the output voltage at the output terminal drops to 75% to 90% of the rated voltage, the red indicator of the S82K (DC LOW indicator) will be lit.
In the case of the S82K-@09024/@10024, a voltage drop alarm will be output via the relay available in the models (DC LOW output).

Note: This function detects the voltage at the output terminal of the Power Supply. To check the precise output voltage, measure the voltage at the

terminal of the load.

Note: 1. The more the voltage at the output terminal drops, the darker both the green and red indicators will be.

2. The relay contacts have a capacity of 0.1 A at 24 VDC.

3. The red indicator will actually first light at a voltage between 75% and 90% of the rated voltage.

If the voltage at the output terminal is more than 82% of
the rated voltage and operation is normal, the green in­dicator will be lit and the red indicator will not be lit.

If the voltage at the output terminal drops to below 82%
of the rated voltage, the red indicator will be lit. (See
note 3.)

If the voltage at the output terminal approaches 0 V,
both the green and red indicators will not be lit.

Item Value Definition

Reliability (MTBF) 135,000 hrs min. MTBF stands for Mean Time Between Failures, which is calculated according to the prob-

ability of accidental device failures, and indicates reliability of devices. Therefore, it does
not necessarily represent a life of the product.

Life expectancy 8 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.

Safety Precautions

!CAUTION

■ Precautions for Safe Use

Mounting

Take adequate measures to ensure proper heat dissipation to
increase the long-term reliability of the product.

The Power Supply is designed to radiate heat by means of natural
air-flow. Therefore, mount the Power Supply so that air flow takes
place around the Power Supply.

When mounting two or more Power Supplies side-by-side, allow at
least 10 mm spacing between them, as shown in the following
illustration.
Forced air-cooling is recommended.

To mount the Power Supply on a DIN rail, hook portion (A) of the
Power Supply to the rail and press the Power Supply toward direction
(B).

To dismount the Power Supply, pull down portion (C) with a flat-blade
screwdriver and pull out the Power Supply.

When tightening the terminals, do not tighten the terminal block to a
torque greater than 75 N.

Selection of 100 or 200 VAC Input
Voltag e
(S82K-@09024/-@10024)

Select a 100 V or 200 V input by shorting or opening the Input Volt­age Selector Terminals, as shown in the following diagram.

(The default setting is 200 V.)

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.

Correct

When connecting the Power Supplies in series with an operation
amplifier, connect diodes to the output terminals as shown by the
dotted lines in the figure. No diodes are required with S82K 90-W/
100-W models.

Minor electric shock, fire, or Product failure may
occasionally occur. Do not disassemble, modify, or repair
the Product or touch the interior of the Product.

Minor burns may occasionally occur. Do not touch the
Product while power is being supplied or immediately
after power is turned OFF.

Fire may occasionally occur. Tighten terminal screws to
the specified torque of 0.98 N·m.

Minor injury due to electric shock may occasionally occur.
Do not touch the terminals while power is being supplied.
Always close the terminal cover after wiring.

Minor electric shock, fire, or Product failure may
occasionally occur. Do not allow any pieces of metal or
conductors or any clippings or cuttings resulting from
installation work to enter the Product.

Charging the Battery

If a battery is to be connected as the load, install an overcurrent limit­ing circuit and an overvoltage protection circuit.

Series Operation

S82K 90-W/100-W models can be operated in series.
It must be noted that the + output of the 7.5-W dual output model
cannot be connected in series to its – output.

Correct

Incorrect

Parallel Operation

S82K 100-W models can be operated in parallel.
Perform parallel operation with power supplies satisfying the same
specifications.

Correct

Note: When operating the S82K-P10024 in parallel operation, set the

switch to “PARALLEL. In this case, the rated current per S82K­P10024 is 3.78 A.

Incorrect

Parallel Operation Precautions

The length and thickness of each wire connected to the load must be
the same so that there is no difference in voltage drop value between
the load and the output terminals of each Power Supply.

Adjust the output voltage of each Power Supply so that there will be
no difference in output voltage between each Power Supply.

Wiring

Do not apply more than 75-N force to the terminal block when
tightening it.

Ensure that input and output terminals are wired correctly.

Minimum Output Current
(S82K-00727/S82K-00728)

The minimum output current of the S82K-00727 and S82K-00728 is
restricted by the output voltage and control method.

Note: All the outputs of the S82K-00727 and S82K-00728 are

controlled by the +V output. If the +V output current falls to 10%
or less of the rated output, the –V output voltage may drop.
