20 / 20 page L-98 Switching Power Supply S82J Generating Output Voltage ( ±) An output of ± can be generated by using two Power Supplies as shown below, because the Power Supply produces a floating output. If operation amplifiers as loads are connected in series, connect a diode between the positive and negative output terminals of each Switching Power Supplies as shown in the illustration below. Without these diodes, the Power Supply may not start when power is turned on, possibly damaging internal circuits over a period of time. Use Schottky barrier diodes with a low forward voltage (V F). Other types of diodes will not be effective. Guidelines for the dielectric strength and current of the diodes are as follows: Dielectric strength: At least twice the rated output voltage of the Power Supply Forward current: At least twice the rated output current No diodes are required for models that allow series operation. Series Operation Only models with power ratings of 50/100/150/300/600 W allow series operation. As shown in the following diagram, the output voltage from each Switching Power Supply can be added. With the S82J-050 @@@@ or S82J-10024@@, if the load is shorted a reverse voltage may result in the Power Supply causing deterioration and damage. It is recommended that diodes are connected as shown in the previous diagram (D 1, D2). Parallel Operation Only 300- and 600-W models can be in parallel operation. Do not operate any other models in parallel. The output of the models in par- allel operation is a maximum of 80% of the rated output. Set the parallel operation selector to PARALLEL if the Units are in parallel operation and 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. Fan Replacement The service life of the fan is approximately 50,000 hours (at 25 °C). The service life varies, however, depending on the ambient tempera- ture or other surrounding environmental conditions such as dust. As a preventive maintenance measure, replace the fan within two years if it is used at an ambient temperature of 40 °C. Fans are available as replacements. Fan Set: Fan (above), four M4 x 35 sems screws, instruction sheet, and pack- ing case Replace the fan as shown in the following illustration. +V −V +V −V +V 0 V −V INPUT INPUT Load Load + V − V + V − V D1 D2 INPUT INPUT Load Load Load +V −V +V −V D1 D2 INPUT INPUT Load Model: S82Y-JFAN In the interest of product improvement, specifications are subject to change without notice.
