Here are all of the steps necessary to set up +9 V and −9 V supply rails. 1. Turn on the power supply with the lower-left power button. 2. Press the +25 V button in the SELECT section and then press the "Display Limit" button to view the voltage setting for that output. Set the voltage limit to 9.00 V using the procedure mentioned above. 1

Often a power supply design team will browse potential thermistors from different suppliers and seek to balance thermistor inrush current characteristics against the impact on power supply efficiency. An example NTC thermistor suitable for inrush current limiting in AC-DC power supplies is the TDK B57464S109M. This thermistor has a nominal

Most AC-DC power supplies and DC-DC converters have internal current-limiting circuits to protect the power device, and to some degree its load. The majority of over-current-protections include an automatic recover feature. In practice, the current-limit circuits typically start operating when the output current exceeds its maximum rating by 10 . 268 219 174 415 48 27 212 356
