Inventronics drivers -any one use these and can test something

[bad inferno]

I think I am going crazy, and cannot really explain what is happening to produce what is 70VAC and can feel a slight tingle in the tank

 

I use 6 x inventronics 350 & 700 mA drivers on my DIY light fixture. I felt a tingle from the tank and have measured approx 70 VAC tank to AC ground. (1.1mA leakage to earth)

 

Now as I turn each of the lights on (1 x Inventronics driver) the AC between tank and ground goes up 10VAC.

 

With no lights on I read something like 17VAC (and 0.1mA to earth) so nothing really

Then as I start to turn on the lights 1 driver at a time it goes up to ~74 VAC. Just does not make sense to me at all. The light fixture is grounded and the inventronics drivers are double insulated. I also thought it maybe induced voltage so rasied the light an additional 12 inches above the tank and did not make any difference to the reading at all.

 

I have a DC return pump, Vortechs and have also turned off my skimmer, heater and rowaphos pump so no other AC appliances in the tank. I would not care however do feel a slight (significant) tingle... so need to track this down.

 

The only other thing I ahve not checked is if my Profilux powerbar has anything to do with it. Over the weekend Ill plug the lights into a normal powerboard and test again.

Unless your light is submerged, it cannot transfer any power into your tank. Saltwater will always show some voltage to ground, but if it's increasing as your drivers are turning on, something is very wrong and you've got a short somewhere. Definitely take your controller's power strip out of the equation, and honestly I'd do it sooner than next weekend.

 

Let us know what you figure out

I would change out your outlet to GFI.

 

Saltwater and electricity can be fatal, youre lucky its only a tingle.

 

Then get a controller to tell you if or when the GFI pops. And get a titanium ground probe if you want to be safe.

Its such a wierd fault, Im going to have to take the light off the aquarium for further testing.... I have access to a test-and-tag appliance tester so may have to resort in taking the light into work and testing. Im predicting it will test 100% as the heatsink is already earthed and the drivers are double insulated. Its a shame Im not measuring a DC voltage then I would blame a shorted LED to heatsink/earth. Im still thinking about this one as the 350ma inventronics driver is capable of 120VDC.. although too strange it increases by 10VAC for every driver I power up.

 

Anyway unplugged the 4 power sockets (used for the lights) off the profilux and powered from a separate powerboard/extension cord... still the same.

I remember that video.

 

Edison only did that to discredit Nikola Tesla. Edison was a huge tool.
