The protection function operates when the load current rises above an overcurrent set value (105% of the rated load current). For a short-circuit or overcurrent lasting less than 20 seconds, output voltage is decreased to protect equipment. When the output current falls within the rated range, the overload protection function is automatically cleared. Output voltage (V) S8PS Overvoltage Protection The Power Supply is provided with an overvoltage protection function that protects the load and the Power Supply from possible damage by overvoltage. When the output voltage rises above a set value (115% of the rated output voltage), the protection function is triggered, shutting OFF the output voltage. If this occurs, reset the Power Supply by turning it OFF for 1 minute min. and then turning it ON again. Output voltage (V) Overvoltage protection operating Rated output voltage Intermittent operation Variable range Rating Output current (%) 0V Note: Do not continue using the S8PS under short-circuited or overcurrent conditions for longer than 20 seconds, otherwise the internal elements of the S8PS may be damaged or broken. 300- and 600-W Models Only The overvoltage protection-ON alarm indicator lights when the function is operating. Overheat Protection Function 600-W Model Only If the internal temperature of the S8PS rises excessively as a result of fan failure or any other reason, the overheat protection circuit will be triggered to protect the internal elements of the S8PS and simultaneously a protection-ON alarm indicator will be lit. To reset the S8PS turn OFF the input voltage, leave the S8PS for at least one minute and then apply the input voltage again. 600-W Models If an excessive current flows for 5 s or more, the output will be turned OFF and simultaneously protection-ON alarm indicator will be lit. To reset the S8PS, turn OFF the input voltage, leave the S8PS for at least three minutes, and then apply the input voltage again. Note: Do not continue using the S8PS with the output terminals short-circuited or the overcurrent condition continued, otherwise the internal elements of the S8PS may be damaged or broken.

[. . . ] Forced air-cooling is highly recommended. It is recommended that the clearance around the Power Supply be larger than those shown on page 3 under Standard Installation. +V INPUT ­V 11 S8PS Parallel Operation Only 300- and 600-W models can be in parallel operation provided that they are operated under 90% of the ratings. Do not operate any other models in parallel. Make sure that the thickness and the length of all wires connected to the load are the same to ensure that the wires will have no voltage drop differences. Load +V INPUT ­V S8PS Fan Set: Fan (above), four M4 x 35 sems screws, instruction sheet, and packing case Replace the fan as shown in the following illustration. +V INPUT ­V Fan Replacement The service life of the fan is approximately 50, 000 hours (at 25°C).
