Attention ! Connecting in parallel of +10V DC not allowed !
Required total current in the example:
= Poti c load current of all fans
= 1,27mA + 3 x 0,33mA = 2,26mA
PU/A Poti burden
= 7,9-16,5kOhm
at 10V
= 1,27-0,6mA
(depend on min. Poti)
Maximum possible number of fans (same types) with the sample fans
= Max. ouput current of the 1st fan - Poti current / load current of a fan
= (10mA - 1,27mA) / 0,33mA = 26,45 = max. 26 fans
