Common Precautions
Ratings, Characteristics, and Functions
*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 Overload Protection on page 20.
*2. 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.
*3. Rated input voltage: 100 or 200 VAC at 100% load.
*4. Output characteristics: Specified at power supply output terminals.
*5. If the output voltage adjuster (V. ADJ) is turned, the voltage will increase by more than the allowable voltage range. When adjusting the output
voltage, confirm the actual output voltage from the Power Supply and be sure that load is not damaged.
*6. For details, refer to Overload Protection on page 20.
*7. To reset the protection, turn OFF the input power for seven minutes or longer and then turn it back ON.
*8. The weight indicated is for Front-mounting, Open-frame Power Supply.
*9. The range for compliance with EC Directives and safety standards (UL, EN, etc.) is 100 to 240 VAC (85 to 264 VAC).

Common Precautions
*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 Overload Protection on page 20.
*2. 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.
*3. Rated input voltage: 100 or 200 VAC at 100% load.
*4. Output characteristics: Specified at power supply output terminals.
*5. If the output voltage adjuster (V. ADJ) is turned, the voltage will increase by more than the allowable voltage range. When adjusting the output
voltage, confirm the actual output voltage from the Power Supply and be sure that load is not damaged.
*6. Measurement methods are based on JEITA standard RC-9131A. Refer to Ripple Noise Voltage on page 57.
*7. For details, refer to Overload Protection on page 20.
*8. To reset the protection, turn OFF the input power for three minutes or longer and then turn it back ON.
*9. The weight indicated is for Front-mounting Power Supply.
*10.The protection-ON alarm indicator will light as soon as the output is interrupted. For resetting, turn OFF the input power, leave for more than
three minutes , and then turn it back ON again.
*11.Noise values depend on the wiring methods and other factors. Insert noise filters and cores in the input and output lines.
300 W, 5 V: Two E04SR401938 (manufactured by SEIWA) on the output line.
300 W, 12 V: One E04SR401938 (manufactured by SEIWA) on the output line.
600 W, 5 V or 12 V: One FN2450G-16-61 (manufactured by Schaffner) on the input line.
One E04RC613620 (manufactured by SEIWA) on the output line.
*12.For the 600-W, 5-V and 12-V models, class A compliance was met with an aluminum plate placed under the Power Supply.
*13.The range for compliance with EC Directives and safety standards (UL, EN, etc.) is 100 to 240 VAC (85 to 264 VAC).

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 a life of the product.
Life expectancy 10 yrs. min.
Definition 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.

When using an input voltage of less than 100 VDC, reduce the load calculated with the above derating curve by at least the following
coefficients.
35-W and 100-W (5-V or 12-V output) models: 0.8

Front-mounting: Refer to Mounting Bracket Provided with Front-mounting Power Supplies on page 26.
. Bottom-mounting
. Side-mounting
Note: Additional mounting methods are also available using DIN Rail-mounting models.
Standard Mounting
Note: 1. Improper mounting will interfere with heat dissipation and may occasionally result in deterioration or damage of internal parts. Use the
standard mounting method only.
2. When mounting the Power Supply, mounting it to a metal plate (*) is recommended.
3. Install the Power Supply so that the air flow circulates around the Power Supply, as the Power Supply is designed to radiate heat by
means of natural air flow.

Note: 1. Improper mounting will interfere with heat dissipation and may occasionally result in deterioration or
damage of internal parts. Use the standard mounting method only.
2. When mounting the Power Supply, mounting it to a metal plate (*) is recommended.
3. Do not cover the air holes (provided at fan mounted side and the opposite side) to have enough air-
cooling.

Common Precautions
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% to 175% min. of the rated current, 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: 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.
2. Internal parts may occasionally deteriorate or be damaged if a short-circuited or overcurrent state continues during operation.
3. Internal parts may possibly deteriorate or be damaged if the Power Supply is used for applications with frequent inrush current or
overloading at the load end. Do not use the Power Supply for such applications.
(Reference value)
If an excessive current flows for 5 s or more, the output will be turned
OFF and simultaneously the protection-ON alarm indicator will be lit.
To reset the S8JX, turn OFF the power, leave the S8JX for at least
three minutes, and then turn it ON again.
