[. . . ] Switch Mode Power Supply S8VS · EMI Class B Compliant 15/30/60/120/240/480 W Models Compact High capacity, Natural Cooling Power Supply Range from 0. 65 A up to 20 A with Output Voltage of 24 VDC · Only 6 models to cover all applications · Output indicator LED green · Mount to DIN Rail. · Complies with SEMI F47-0200 (200 VAC input). · Safety standards: UL508/60950-1, CSA C22. 2 No. 107. 1/60950-1 (60 W to 480 W), EN50178 (= VDE0160), EN60950-1 (= VDE0805 Teil 1) Note: Refer to Safety Precautions on page 11 Model Number Structure Model Number Legend S8VS- [. . . ] If there is a derating problem, use forced air-cooling. When using a 480 W model at an input voltage of 95 VAC or less, derate the load by at least 80%. 7 S8VS Output voltage (V) Overload Protection The load and the power supply are automatically protected from overcurrent damage by this function. Overload protection is activated if the output current rises above 105% of the rated current. When the output current returns within the rated range overload protection is automatically cleared. 15-W Models Output voltage (V) Output voltage (V) 30-W Models +30% (approx. ) +15% Overvoltage protection operating Rated output voltage -10% Variable range 0V Intermittent operation The values shown in the above diagram is for reference only. 0 50 100 Output current (%) 0 50 100 Output current (%) 60 W Models Output voltage (V) 120 W/240 W/480 W Models Output voltage (V) Note: 1. Do not turn ON the power again until the cause of the overvoltage has been removed. The overvoltage protection of the S8VS-01524 uses a zener diode clamp. The output voltage will be clamped at approx. 140% or higher of the rated output voltage (approx. If the internal feedback circuit is destroyed by any chance, the load may be destroyed by the clamped output voltage (approx. 140% to 190% of the rated output voltage). The power Supply will not restart if the output is turned OFF by the overvoltage protection operation. If this occurs, replace the Power Supply. Undervoltage Alarm Indication LED (DC LOW red) lights to warn of output voltage drop. 80% (75 to 90%) of the rated output voltage. Note: This function monitors the voltage at the power supply output terminals. To check actual voltage, measure voltage on the load side. Intermittent operation 0 50 100 0 50 100 Output current (%) Output current (%) The values shown in the above diagrams are for reference only. Note: 1. Internal parts may occasionally deteriorate or be damaged if a short-circuited or overcurrent state continues during operation. 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 Values (15 W to 480 W Models) Item Value Definition MTBF stands for Mean Time Between Failures, which is calculat15 W to 240 W: ed according to the probability of 135, 000 hrs min. accidental device failures, and 480 W: indicates reliability of devices. Therefore, it does not necessarily represent the life of the Product. 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. Peak Output Current (S8VS-48024 only) The peak current must satisfy the following conditions. [. . . ] Do not use the Power Supply in locations subject to direct sunlight. Do not use locations where liquids, foreign matter, or corrosive gases may enter the interior of Products. 11 S8VS Overcurrent Protection Internal parts may possibly deteriorate or be damaged if a short-circuited or overcurrent state continues during operation. 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. Series Operation Two power supplies can be connected in series. Correct AC (L) AC (N) +V -V Dielectric Strength Test If a high voltage is applied between an input and the case (FG), it will pass though the LC of the built-in noise filter and energy will be stored.
