Test Procedure

Use the following steps for the test procedure:

  1. Set the power supply current limit to 10 A. Set the power supply to something around 12 V. Turn off the power supply. Connect the positive output of the power supply to J1 and the negative output to J2.
  2. Connect the load to J3 for the positive connection and J4 for the negative connection.
  3. Turn on the power supply.
  4. Slowly increase the load while monitoring the output voltage between J3 and J4. It must remain in regulation when the load current is lower than 4 A.
  5. Slowly sweep the input voltage from 9 V to 20 V. The output voltage must remain in regulation when the load current is lower than the maximum load current specified in Table 2-1.
  6. Turn off the load, turn off the power supply. Then turn on the load to discharge the output capacitors.
