Dali power injector circuit - an LM317(TO263)+ 5R1(2512) resistor, which will limit the current on the two DALI pins to about 240mA. Identical to DALI power board 1 but with a bigger footprint which should allow it to deliver that 240ma without the thermal limiting kicking in.
SS14+1M ensure that if power is supplied to the bus elsewhere, the LM317 will not be damaged. 1M is to get rid of leakage current from SS14, not sure if it’s required.
