Ambient temperature (°C) Note that the derating curve may vary depending on the installation conditions. Multiple units cannot be installed in a configuration where they are lined up vertically. The cold-start time will be longer when using S82K-P09024 or S82K-P10024 with 85-VAC input. Mounting Top Top Note: Installations other than (A) and (B) are not possible. (A) Standard mounting (B) Face-up mounting Switch Mode Power Supply S82K 7 Overload Protection The Power Supply is provided with an overload protection function that protects the Power Supply from possible damage by overcurrent. 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. 3-/7. 5/15 W Models Output voltage (V) 30-/50 W Models Output voltage (V) 90-/100 W Models Output voltage (V) Intermittent operation 0 50 100 Output current (%) 0 50 100 Output current (%) 0 50 100 Output current (%) Note: 1. When connecting a load that has a built-in DC-DC converter, the overcurrent protection function may operate during start-up, thus preventing the Power Supply from starting. Internal parts may occasionally deteriorate or be damaged if a short-circuited or other overcurrent state continues during operation. 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. 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 protection function will operate at currents from 92% to 111% of the rated output current. 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. 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. Indicator Voltage Operation of @09024/@10024's output (DC LOW output) (See note 2. ) Green: Red: Green: Red: Green: DC ON DC LOW DC ON 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% (See note 1. ) of the rated voltage, the red indicator will be lit. (See note 3. ) DC LOW If the voltage at the output terminal approaches 0 V, both the green and red indicators will not be lit. DC ON Red: DC LOW Note: 1. The more the voltage at the output terminal drops, the darker both the green and red indicators will be. The red indicator will actually first light at a voltage between 75% and 90% of the rated voltage. 8 Switch Mode Power Supply S82K Inrush Current, Startup Time, Hold Time Input ON AC input voltage Input OFF Inrush current on input application AC input current 90% Output voltage Startup time: 100 to 1000 ms max. Hold time (20 ms min. ) 96. 5% Reference Value Item Reliability (MTBF) Value 135, 000 hrs min. Definition MTBF stands for Mean Time Between Failures, which is calculated according to the probability of accidental device failures, and indicates reliability of devices. The life expectancy indicates average operating hours under the ambient temperature of 40°C and a load rate of 50%. [. . . ] Correct 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.

In this case, the rated current per S82KP10024 is 3. 78 A.
