1.5 Test Setup

The following steps are used for the test setup:

  1. If the UCD3138 control card is new, flash the code into the card (skip this step if the card is pre-flashed)
  2. Insert the UCD3138 control card and the auxiliary power board into the base board
  3. Connect the input DC source and output electronic load
  4. Consider using an extra cooling fan to minimize the temperature of the power board
  5. Power on the DC source with 400 V, the 12-V output automatically starts up
