    simple current limiting to 2A with TIP122

    this is elevator 7 segment display and we have 8 floor and 8 7 segment too . In step installing Possible short circuit too much (24V With a,b,c,d,e,f,g) and when +24 connected to a(7segment sc) one LED in Circuit on and we realized getting short-circuited . i need a circuit limit current to...

    simple current limiting to 2A with TIP122

    I have think that each segment will take 30 mA Seven segment was a 210 mA current I have 8 Seven Segment result 1680 mA and a current limiting 2A need So how do the Chinese Limit the current with TIP122 without cooling ? Possible short circuit too much But at the time of short circuit LED short...
