J-Testr Load Breakout Card
AboutThe Load Breakout card gives independent access to both Load A and Load B via ‘easy to use’ screw terminal blocks. Each load block also contains the load voltage measurement lines immediately adjacent to its load terminal.
By default the load measurement is attached to the high voltage measurement input line with an optional fit zero-ohm 0805 SMT link to connect to the low voltage measurement input line. The voltage measurement ground is connected to the common ground but for remote negative sensing it can be removed using another zero-ohm 0805 SMT link. The Load Breakout card UserIO (GPIO) lines are taken to eight clearly marked 1mm diameter test-point holes. The card also contains 3 extra common grounding points. Warning: The common negative load lines are connected to the system Common Ground. |
