Helvar Using the PCB Iset current selection 1] To configure the LL1x21-CC for 300 mA output, the pre-cut piece of PCB must be removed. The piece is Located next to input connector PE terminal, pLease see the illustration of PCB Iset piece in the Figure 1. 2] The recommended tool for removing the PCB Iset piece is sidecutting pliers, as seen in the Figure 2. 3] First cut the side of the PCB Iset piece following the pre-cut Line, as seen in the Figure 3. 4] Next, snap the PCB Iset piece off of the main PCB. 5] Remove the piece completely, as seen in Figure 4. 6] Take special attention, that - cutting...
