Generally is it safe to say that the controllers (power supply) for swcg's are designed as a constant current source?
Pentair tries to keep the current constant by changing the voltage.Generally is it safe to say that the controllers (power supply) for swcg's are designed as a constant current source?
Is your first lesson dealing with electricity “ water and voltage don’t mix especially salt water”Not sure I understand the wording of your question but if you are asking if SWGs are electrically safe then the answer is -
Yes, as long as the they are properly installed to code with the appropriate wiring and bonding used.
I have yet to see an article of anyone randomly being electrocuted by an SWG that was properly installed.
I bet that guy who does the voltage videos James post would never have a salt pool. Heck he probably has a belt driven pumpPure water has a resistance of approximately 18.9 mega-ohms. That is double distilled, deionized water delivered in non-metallic piping. “City water” that is clean and low mineralization has a resistance of about 0.1 mega-ohm. The stuff in your pool is a lot lower resistance than city water.
The first lesson I learned in EE-101 was -
V = I • R
Which then shortly turned into -
Matt,
what the S?
Just wondering how the controller worked.Not sure I understand the wording of your question but if you are asking if SWGs are electrically safe then the answer is -
Pentair and Jandy measure the current and adjust the voltage to try to keep the current within a specific band.Regardless of whether the current or voltage to the cell is being controlled , the current is being measured and acted upon.
