Smps grounding
Web5 Aug 2013 · It is connected between the hot ground and the cold ground of the SMPS. The hot ground (primary) voltage usually stands half way between Life and Neutral, i.e 120 V AC. The reactance (AC resistance) of a 3,300 pF capacitor at 50 Hz is 965 kΩ. So the cold ground of our SMPS is like a voltage source of 120 VAC with an internal resistance of 965 … Web5 Mar 2008 · Here's a little about the amp, power supply is a smps with 28.5v rails, good amount of filtering and isolated ground (relative to the rest of the car) there are 4 lm3886's in a fairly standard non-inverting setup, each pair of input rca's shares a common ground (that's how the rca block is built) and there is a wire from that point to the star ground) now when …
