S8VK-T Overvoltage Protection (A) Standard (Vertical) mounting (B) Face-up mounting Overload Protection Output voltage (V) 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 121% of the rated current. When the output current returns within the rated range, overload protection is automatically cleared.

S8VK-T Safety Precautions Warning Indications CAUTION Indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate injury or in property damage. Precautions for Safe Use Supplementary comments on what to do or avoid doing, to use the product safely. Precautions for Correct Use Supplementary comments on what to do or avoid doing, to prevent failure to operate, malfunction or undesirable effect on product performance.
S8VK-T Precautions for Safe Use Wiring Connect the ground completely. A protective earthing terminal stipulated in safety standards is used. Electric shock or malfunction may occur if the ground is not connected completely. Minor fire may possibly occur. Ensure that input and output terminals are wired correctly. Do not apply more than 75-N force to the terminal block when tightening it.
S8VK-T Mounting Power Boost Function Take adequate measures to ensure proper heat dissipation to increase the long-term reliability of the Product. Be sure to allow convection in the atmosphere around devices when mounting. Do not use in locations where the ambient temperature exceeds the range of the derating curve. When cutting out holes for mounting, make sure that cuttings do not enter the interior of the Products.
S8VK-T The outputs are floating outputs (i.e., the primary circuits and secondary circuits are separated). You can therefore make positive and negative outputs by using two Power Supplies. You can make positive and negative outputs with any of the models. If positive and negative outputs are used, connect Power Supplies of the same model as in the following figure. (Combinations with different output capacities or output voltages can be made.
S8VK-T Backup Operation In Case There Is No Output Voltage Backup operation is possible if you use two Power Supplies of the same model. Even if one Power Supplies fails, operation can be continued with the other Power Supply. Make sure that the maximum load does not exceed the capacity of one Power Supply. For backup operation, connect the S8VK-R for 120 W, 240 W, and 480 W. Refer to the S8VK-R datasheet (Catalog No.: T059) for S8VK-R specifications and the model number for each capacity.
S8VK-T Recommended Replacement Periods and Periodic Replacement for Preventive Maintenance The recommended replacement period for preventive maintenance is greatly influenced by the application environment of the product. As a guideline, the recommended replacement period is 7 to 10 years.* To prevent failures or accidents that can be caused by using a product beyond its service live, we recommend that you replace the product as early as possible within the recommended replacement period.
