coupling resistor on power conditioner output
gkmaia:
I got a Furman power conditioner that has a faulty resistor. R7 on the left of the schematics on the output block has burned to death... so cannot read it.
Could anyone give me a hand to understand what a resistor on that circuit design does and it's likely value?
oschonrock:
What is being connected at Tab10/Tab6? Is that the output of the conditioner?
Where did you get this schematic from? Are you sure all of D9/D10/D11/D12 are the correct way around?
gkmaia:
You were right. D12 was inverted. Fixed it and uploaded a new one to my previous post.
NiHaoMike:
Appears to be just a bleeder for the overshoot dampening circuit. A 330k, 1W resistor will work well with fairly low power dissipation, just beware it will take some time to discharge the cap. Add a blue LED in series as a visual indication of voltage.
gkmaia:
thanks for the reply. So this basically allows to extra overshot voltage to be feed to C7 maintaining the voltage somewhat more stable?
So this means, it will still work with no resistor there. It will just not smooth the AC as well as it could?
