The following graph shows the overload detection and reset operation of the S8E3. Rated voltage Output current (%) Type Operating method Detection Reset V1 Inverted drop 105% min. of rated load current Automatically resets when the output current returns to normal V2, V3 Short-circuit protection --- Automatically resets when the output current returns to normal Note: 1. The overload protection function of output V1 is triggered when the total output of V1, V2, and V3 exceeds the permissible output capacity of the S8E3 (total overcurrent protection). If outputs V2 and V3 are within their rated currents, overload protection for V1 operates with its output current is 105% or more of the rated output current. Caution is required, however, because operation depends on the output status of outputs V2 and V3. 2. V2 and V3 have an independent short-circuit protection function. 3. Do not continue operating the S8E3 if an output terminal is short-circuited or overloaded, or the S8E3 may incur output voltage fluctuation, internal element deterioration, or damage. J OVERVOLTAGE PROTECTION (V1 OUTPUT ONLY) Output voltage (V) 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 (120% of the rated output voltage), the protection function is triggered, shutting off all of the output voltage. If this occurs, reset the Power Supply by turning it off for 1 minute min. and then turning it on again.

Load current (%) The rated current of the S8E3-05031j is 1.5 A at 12 V. The peak load current of the S8E3-05031j is available at 12 V under the following conditions, in which case the waveform of the load current must satisfy the following formula.

Switching Power Supply S82K Precautions J MOUNTING Mounting Screws • When tightening the mounting screws into the power supply, do not allow them to penetrate more than 4 mm into the power supply. • To improve and maintain the reliability of the Power Supply over a long period of time, mount the Power Supply so that air flow takes place around the Power Supply. The Power Supply is designed to dissipate heat through natural air-flow. Forced-air cooling is recommended. Two (or More) Power Supplies Mounted Side-by-Side When mounting two or more Power Supplies side-by-side, allow at least 20 mm spacing between them, as shown in the following illustration. Penetration of Metal Filings and Cuttings If drilling and other work is carried out over the power supply, metal filings, cuttings, and other materials may fall onto the printed circuit boards inside the power supply, leading to internal shorts and damage. If it is necessary to work over top of the power supply, cover the power supply with a sheet or other suitable material to prevent the entry of foreign matter into the power supply. This step is necessary even if the power supply is equipped with a cover. After completing the above work and before supplying power, remove the sheet to avoid interference with appropriate cooling. 20 mm min. $//',0(16,2166+2:1$5(,10,//,0(7(567RFRQYHUWPLOOLPHWHUVLQWRLQFKHVGLYLGHE\ 20521(/(&7521,&6//& 2QH&RPPHUFH'ULYH 6FKDXPEXUJ,/  )RU86WHFKQLFDOVXSSRUWRURWKHULQTXLULHV 20521&$1$'$,1& 2052121/,1(  *OREDOKWWSZZZRPURQFRP 86$KWWSZZZRPURQFRPRHL &DQDGDKWWSZZZRPURQFD 0LOQHU$YHQXH 7RURQWR2QWDULR0%9  Cat No. GC PS6 2/03 Specifications subject to change without notice Switching Power Supply Printed in USA S8E3 8
