Re: I Need Better Capacitor Understanding

My meter would not read this capacitor so I had someone else read it (out of the circuit). I was told it was not within tolerance. Sorry, but I do not know the actual reading.

I still have the capacitor though and if that is important I can have it read again.

R_J:

It is a spa valve actuator. However the model number I have is PE24VA. I believe it is identical to the Pentair CVA-L24.

Budm:

I am sure your drawing of the motor is accurate as it is a reversible motor.

Concerning the question in your second drawing the wiring goes to the spa control panel.

Concerning my wording "does not function" what I mean is that I have determined that the capacitor is bad and does not produce a reading on my meter. I apologize...

Re: I Need Better Capacitor Understanding

I cannot answer you last question as the existing capacitor does not function.

Yes I do believe the capacitor is for the AC motor.

So that leaves me with finding a replacement.

Like I mentioned, I have found similar capacitors rated at 50V, so as this is being placed in a 24V circuit why do I need a 100V capacitor?

Can you recommend a capacitor that would be suitable as a replacement? In the current state of quarantine I need to order on line.

Thanx...

Re: I Need Better Capacitor Understanding

First, just a reminder that, as previously stated, I am trying to learn.

I kind of don't understand concerning the +-20% thing for two reasons. First, I don't know where that tolerance came from... I didn't list it and I don't see it in the schematic drawing. Second, if the tolerance of a 33uf capacitor is at minus 20%, that would make the capacitor rating below the schematic requirement.

Concerning the voltage, I do understand that a higher voltage capacitor can be used to replace a lower voltage IF it fits...

Re: I Need Better Capacitor Understanding

1) See uploaded file.

2) There is no circuit board.

3) Tested bad....

I have been having trouble acquiring an exact match for a capacitor that apparently activates a motor in my spa valve control. The schematic details a 35uf 100V 83c non-polar cap. On Line I have found many close to these specs but none are exact. Accordingly, I need to know how much these values can fluctuate. I did find a capacitor with the values 35uf 50V 83c non-polar and I have also noticed that the schematic diagrams indicate that this circuit operates using 24VAC. So can I use a 50V cap? I have also found many that are rated at 33uf and up to 250V. I know that having the capability of 250V...
