Greetings all! I contemplate
using ADC-11 to supervise voltages and temperatures in a charging
apparatus for up to 4 cells. The currents may be up to 2A per cell
and I contemplate getting this DC current, at low voltage (maybe only
5V DC) from a 250V 50Hz mains unit (?maybe from the desktop computer's power supply?).
i) Am I right in understanding that all signals
connected to the ADC- 11 must be grounded to the ground of the
computer's motherboard? Ie, the charging circuit(s) would have to be
grounded to the ground of the computer's motherboard?
ii) How can I
get an overview of the options/ techniques for ensuring that the
charging apparatus, and the ADC-11, do not become connected to any
mains-side conductor? Eg, how is the mains in a printer, or in an
external mains power supply for a laptop, isolated from the low-
voltage circuits which are connected to the computer? Is it normal
for the mains earth to be connected to the computer casing and/or
motherboard earth? Can anyone refer me to document(s) on this matter?
Thanks in anticipation.
