When the output current rises to 105% or higher 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. ■ Inrush Current, Startup Time, Hold Time Input ON Input OFF AC input voltage Inrush current on input application AC input current 96.5% 90% Output voltage 0 50 100 ms (max.) startup time 20 ms (min.) hold time 100 Output current (%) The values shown in the above diagram are for reference only. Note: Internal parts may occasionally deteriorate or be damaged if a short-circuit or other overcurrent state continues during operation. Eliminate the overcurrent state as soon as possible. Dual Output Models The total output power for the +V output and −V output is detected for the protection operation (i.e., total overcurrent protection), but this condition varies depending on –V output status. –V output has an independent short-circuit protection feature. 4 S82S Dimensions Note: All units are in millimeters unless otherwise indicated.

Do not disassemble, modify, or repair the Product or touch the interior of the Product. Minor burns may occasionally occur. Do not touch the Product while power is being supplied or immediately after power is turned OFF. A Fire may occasionally occur. Tighten terminal screws to the specified torque of 0.74 N·m (M3.5). Minor injury due to electric shock may occasionally occur. Do not touch the terminals while power is being supplied. B When mounting to a DIN Rail, lower the S82S onto the Rail until the Rail stopper clicks into space, hook section A over the edge of the Rail, and push in the direction of B. Minor electric shock, fire, or Product failure may occasionally occur. Do not allow any pieces of metal or conductors or any clippings or cuttings resulting from installation work to enter the Product. Mounting Rail stopper To improve and maintain the reliability of the power supply over a long period of time, adequate consideration must be given to heat radiation. The power supply is designed to radiate heat by means of natural airflow. Therefore, mount the power supply so that air flow takes place around the power supply. 30 mm min. To remove the S82S from the DIN Rail, insert a screwdriver into section C and pull the S82S away from the Rail. Serial or Parallel Operation No serial or parallel operation is available. The positive and negative output terminals of a Dual Output Model cannot be connected in series to operate. Incorrect Air +V When mounting two or more power supplies side-by-side, allow at least 10 mm spacing between them, as shown in the following diagram. Forced air-cooling is recommended. INPUT −V +V 10 mm min. INPUT −V Incorrect +V INPUT −V +V INPUT Wiring −V Do not apply more than 75-N force to the terminal block when tightening it. Minimum Output Current (S82S-7727 and S82S-7728) The minimum output current of the S82S-7727 and S82S-7728 is restricted by the output voltage and control method. Note: All the outputs of the S82S-7727 and S82S-7728 are controlled by the +V output. If the +V output current falls to 10% or less of the rated output, the –V output voltage may drop. ALL DIMENSIONS SHOWN ARE IN MILLIMETERS. To convert millimeters into inches, multiply by 0.03937. To convert grams into ounces, multiply by 0.03527.
