[. . . ] When output current falls within the rated range, the overload protection function is automatically cleared. Overvoltage Protection 5 A and 10 A models If output voltage exceed the rated voltage more than 25% (50% at maximum) by some reason, then the output voltage will be automatic limited for safety. 20 A and 40 A models If output voltage exceed the rated voltage more than 25% (50% at maximum) by some reason, then the output voltage will be turned OFF automatically for safety. To restart the S8VT, turn OFF the input voltage, wait few minutes, then apply the input power again. De-rating Curve P Pmax 50% 60 70 °C For UL and CSA the maximum temperature is 60°C (70°C for the 20 A model) 3 S8VT Dimensions and Nomenclature Note: All dimensions shown are in millimeters.

DIN-rail clip 4 S8VT Notice Three phase input operation when one phase is missing The S8VT will in most cases continue to operate even after the loss of one phase of the supply. The performance specifications are of course not guaranteed under these conditions. As the loss of one phase puts additional stress on some components, the life span of the unit could be shortened. It is prudent therefore to regularly check for signs of the following possible conditions. Incorrect/No voltage on one or more phases of the supply. Abrupt or periodical loss of input voltage. The power supply needs output derating as in the chart for the operation on missing phase at the input voltage range of 340 to 576 V. Otherwise, the power supply may deteriorate or be damaged. In every single application suitability has to be checked. Missing phase de-rating 110 100 90 80 70 Load 60 (%) 50 40 30 Load Serial Operation As shown below, the output voltage from each S8VT can be added. Types must be the same. +V -V +V -V Parallel Operation As shown below, two S8VT-F (same capacity model) can be paralleled to boost the output power (current). Set the output voltages of the Power Supplies to the same value. Also, 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 difference. Parallel connection is only permissible with ambient temperature from -10°C to +50°C. [. . . ] To convert millimeters into inches, multiply by 0. 03937.
