Internal parts may occasionally be deteriorated or damaged. Do not use the Power Supply in areas outside the derating curves (i.e., the area shown by shading A in the above graphs). 2. If there is a derating problem, use forced air-cooling. 3. When mounting two or more Power Supplies side-by-side, allow at least 20 mm spacing between them. Multiple 100- and 150-W models cannot be used side by side. Be sure to install the Power Supplies as far away from heat-generating sources as possible. As a reference value, allow at least 50 mm spacing on the right and left sides. If only 20 mm spacing is allowed, use the Power Supply at a load ratio of 80% or less. 4. When using 150-W models for a long period of time at an input voltage of 90 VAC or lower, reduce the load to 80% or less of the above derating curves.

Use a 2-conductor shielded cable as a connection wire (*1). 2. Use as thick a wire as possible since high voltage drops on the load lines (*2) may activate the overvoltage protection function. 3. Use when the voltage drop is 0.3 V or lower. 4. When the +S and -S terminals are opened with the short bar removed, the overvoltage protection function is activated and the output voltage will be cut off. 5. If the load line is too long, use an electrolytic capacitor in the following 3 locations: 1) Across the load terminals 2) Between the +S terminal and + terminal 3) Between the -S terminal and - terminal Select the capacity of the connected capacitor from between several tens to several hundreds of F as a guide, and then determine the capacity when actually connecting the capacitor between terminals as shown below. + V.ADJ DC ON +S + +V -V + -S *1 Face-down mounting (DIN Rail mounting bracket type) Face-down mounting (Front-mounting type) Incorrect Incorrect Inrush Current, Start Up Time, Output Hold Time Input OFF Input ON AC input voltage Inrush current on input application AC input current 95% 90% Note: 1. Improper mounting will interfere with heat dissipation and may occasionally result in deterioration or damage of internal parts. Use the product within the derating curve for the mounting direction that is used. 2. Use the metal plate as the mounting panel (*1). 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. 4.

MTBF stands for Mean Time Between Failures, which is calculated according to the probability of accidental device failures, and indicates the reliability of a device. 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 40C and a load rate of 50%. Normally this is determined by the life expectancy of the built-in aluminum electrolytic capacitor. Overload Protection Overvoltage Protection 50/100/150W (5 V) Output voltage (V) Intermittent operation 0 50 Consider the possibility of an overvoltage and design the system so that the load will not be subjected to an excessive voltage even if the feedback circuit in the Power Supply fails. When an excessive voltage that is approximately 140% of the rated voltage or more is output, the output voltage is shut OFF, preventing damage to the load due to overvoltage. Reset the input power by turning it OFF for at least three minutes and then turning it back ON again. Output voltage (V) 15/30W Output voltage (V) The Power Supply is provided with an overload protection function that protects the Power Supply from possible damage by short-circuit and 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. 0 Variable range +20% Intermittent operation 100 Output current (%) Overvoltage protection operating Approx. 40% *1 Rated output voltage *2 -10% 50 100 Output current (%) -20% Output voltage (V) 50/100/150W (12 V, 15 V, 24 V) 0V The values shown in the above diagram are for reference only. *1 S8VM-@@@24A@/P@ *2 Except for S8VM-@@@24A@/P@ 0 Note: 1. Do not turn ON the input power again until the cause of the overvoltage has been removed. 2.

Note: 1. Internal parts may occasionally deteriorate or be damaged if a short-circuited or other overcurrent state continues during operation. Eliminate the overcurrent state as soon as possible. 2. Internal parts may possibly be deteriorated or 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. Undervoltage Alarm Function (Indication and Output) (Only S8VM-@@@24A@/P@) If an output voltage drop is detected with an S8VM-@@@24A@/P@ with undervoltage alarm function, the DC LOW indicator will light to notify of an output error. The transistor also sends an output externally to notify of the error (except for the S8VM-01524A@ and S8VM-03024A@). Transistor Output: Sinking type: (NPN) (S8VM-@@@24A@) Leakage current when OFF: 0.1 mA or less Sourcing type: (PNP) (S8VM-@@@24P@) 30 VDC max., 50 mA max.Residual voltage when ON: 2 V or less S8VM-01524A@ S8VM-05024A@/P@ S8VM-10024A@/P@ S8VM-15024A@/P@ S8VM-03024A@ 8 9 10 4 4 7 6 4 8 9 10 6 7 7 6 10 9 8 4 7 6 * Undervoltage Alarm Function 1 (DC LOW1) Only a momentary voltage drop is detected. Detection voltage is automatically adjusted internally by detecting the output voltage (approx. 2.7 V lower than the voltage output at an output voltage of 24.0 V). During detection, the transistor is OFF (with no continuity across 8 and 10) and the LED (6: Yellow) lights. (The Undervoltage Alarm Function 1 is used as a latch holding function.) * Undervoltage Alarm Function 2 (DC LOW2) Detection voltage is set to approx. 20.0 V (from 18.0 to 21.6 V). During detection, the transistor is OFF (with no continuity across 9 and 10) and the LED (7: Red) lights. Note: 1. This function monitors the voltage at the Power Supply output terminals. To check actual voltage, measure voltage on the load side. 2. Gradual voltage drop is not detected by the Undervoltage Alarm Function 1 (DC LOW1). 3. Once undervoltage is detected by Undervoltage Alarm Function 1 (DC LOW1), the transistor turns OFF and status of the LED (6: Yellow) light is maintained. To reset the function, turn OFF the input power for 60 seconds or longer, and then turn it ON again. 4. If the output voltage remains at 15 V or lower for several seconds when using Undervoltage Alarm Function 1 (DC LOW 1), the output hold status for detection may be reset.

(Only S8VM100@@@@/150@@@@) Keep the Power Supply as far away from heating elements as possible when installing. As a reference value, allow at least 50 mm spacing on the right and left sides. If only 20 mm spacing is allowed, use the Power Supply at a load ratio of 80% or less. 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. S8VM-100@@@@/S8VM-150@@@@ Incorrect Fire may occasionally occur. Tighten terminal screws to the specified torque of 1.6 N*m. Incorrect Minor injury due to electric shock may occasionally occur. Do not touch the terminals while power is being supplied. 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. Connect the ground completely. A protective earthing connection stipulated in safety standards is used. Electric shock or malfunction may occur if the ground is not connected completely. Precautions for Safe Use Minor fire may possibly occur. Ensure that input and output terminals are wired correctly. Mounting Do not apply more than 100 N force to the terminal block when tightening it. Standard mounting (DIN Rail mounting bracket type) Be sure to remove the sheet covering the Product for machining before power-ON so that it does not interfere with heat dissipation.

For details, refer to the JST catalog. * Use a wire size of AWG22 to AWG28. * The guideline for the length of sheath to be stripped from the wire is 2.1 to 2.6 mm. * Use either a YC or YRS Crimping Tool (manufactured by JST) to crimp the terminal and wire. * Be sure to insert the crimped terminal wires into the housing fully until a click is heard. Also, make sure that the wires attached to the housing are securely locked in place. Installation Environment Do not use the Power Supply in locations subject to shocks or vibrations. In particular, install the Power Supply as far away as possible from contactors or other devices that are a vibration source. Install the Power Supply well away from any sources of strong, highfrequency noise and surge. Operating Life The life of a Power Supply is determined by the life of the electrolytic capacitors used inside. Here, Arrhenius Law applies, i.e., the life will be halved for each rise of 10C or the life will be doubled for each drop of 10C. The life of the Power Supply can thus be increased by reducing its internal temperature. Ambient Operating and Storage Environments Store the Power Supply at a temperature of -25 to 65C and a humidity of 25% to 90%. The Internal parts may occasionally be deteriorated or damaged. Do not use the Power Supply outside the derating range (i.e., under conditions indicated by the shaded area ( ) in the derating curve diagrams on page 7.) If a battery is to be connected as the load, install an overcurrent limiting circuit and an overvoltage protection circuit. Dielectric Strength Test If a high voltage is applied between an input and the case (PE/FG), it will pass though the LC of the built-in noise filter and energy will be stored. If the high voltages used for dielectric strength testing are turned ON and OFF with a switch, timer, or similar device, impulse voltage will be generated when the voltage is turned OFF and internal parts may possibly be damaged. To prevent the generation of impulse voltages, reduce the applied voltage slowly with a variable resistor on the test device or turn the voltage ON and OFF at the zero-cross point. When performing the test, be sure to short-circuit all the output terminals to protect them from damage. Insulation Test When performing the test, be sure to short-circuit all the output terminals to protect them from damage. Inrush Current When two or more Power Supplies are connected to the same input, inrush current is added to the total current. Select fuses and circuit breakers giving sufficient consideration to the fusing or operating characteristics so that fuses will not burn and breakers will not break due to inrush current. Output Voltage Adjuster (V.ADJ) Default Setting: Set at the rated voltage Adjustable Range: Adjustable with output voltage adjuster (V.ADJ) on the front panel of the Product from -20% to 20% of the rated output voltage (-10% to 20% of the rated voltage for S8VM-@@@24A@/P@) Turning clockwise increases the output voltage and turning counterclockwise decreases the output voltage. The output voltage adjuster (V.ADJ) may possibly be damaged if it is turned with unnecessary force. Do not turn the adjuster with excessive force. After completing output voltage adjustment, be sure that the output capacity or output current does not exceed the rated output capacity or rated output current. The output voltage may increase beyond the allowable voltage range (up to +20% of the rated voltage) depending on the operation of the output voltage adjuster (V.ADJ). When adjusting the output voltage, check the output voltage of the Power Supply and be sure that the load is not damaged. When increasing the output voltage to more than +20% of the rated value using the output voltage adjuster (V. ADJ), the overvoltage protection function may operate. (S8VM-@@@24A@/P@ Only) Use the Power Supply at a humidity of 30% to 85%. Turn the output voltage adjuster (V.ADJ) slowly. When decreasing the output voltage quickly, or when adjusting the output voltage to less than -10% of the rated value, the undervoltage alarm function may operate. Do not use the Power Supply in locations subject to direct sunlight. DIN Rail Mounting Do not use the Power Supply in locations where liquids, foreign matter, or corrosive gases may enter the interior of the product. Overcurrent Protection Internal parts may occasionally deteriorate or be damaged if a shortcircuited or other overcurrent state continues during operation. Eliminate the overcurrent state as soon as possible. Internal parts may possibly be deteriorated or 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. When mounting to a DIN Rail, lower the S8VM onto the Rail until the Rail stopper clicks into place, hook section A over the edge of the Rail and push in the direction of B.

If the load is short-circuited, a reverse voltage may be applied inside the Power Supply unit, and this may possibly cause the deterioration or damage of the Power Supply unit. Connect the diode as shown in the figure. Use the following guidelines to select the diode to be connected. 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 internal operation stabilizes and does not indicate any problem in the Product.
