    simple current limiting to 2A with TIP122

    8 Seven Segment are Parallel i dont want limit per segment or 1 7segment i want limit for total 8 7segment Do not change issue You do not understand me IF you have limiter 2A with Signal LED Offer it , otherwise Do not ideas

    simple current limiting to 2A with TIP122

    no we have 7 TIP122 in circuit and 1 tip122 limit current . we drive simple 1 7segment in floor we have (a.b.c.d.e.f.g) with common +24 and show number p to 8 Come on i need a circuit limit current to 2A have Signal LED TOO

    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...

    simple current limiting to 2A with TIP122

    I realized This is not limiting 2A I can not test this circuit Because is working Do you think that how many watts? can help to find the diagram?
