Three-prong DC power supply for LED Strip Lights

Your under-counter strip lights were recommended to me, the FilmGrade™ DC Power Supply for LED Strip that was recommended to go with it has a 2-prong cord on the wall outlet side. I am sensitive to electric fields and was wondering if I could get a three-prong (grounded) power supply to be used with the light strip so there will be no electric field radiating from the power pack or its cord and it also will not radiate electric field down the length of the light strip. 

Unfortunately, we do not have any grounded plug connection option for our DC power supply units. We apologize!

In the meantime, if you can locate any third-party power supplies with a three-prong plug connection, I would be more than happy to review them for compatibility with our LED strip lights on the DC output side.

I had just been in touch with a supplier to see if they had a grounded power pack with the specifications to replace the ungrounded unit that is for the equipment I have, they did, but unfortunately, you would have to order 1,000 as a minimum order because all are custom made. Maybe you could give me the specifications that are needed on the DC side and I can run it past the second company.

The primary power specifications are:

• Input voltage - 12 volts DC or 24 volts DC
• Power capacity - 5.5 watts per foot (90 watts per reel) + 20% overhead

The power capacity specification is the one variable specification that you'll want to make sure you have correct with the power supply manufacturer. The "watts per foot" requirement would be based on the total length of the LED strip light you plan on installing.

​For example, if you are installing 10 feet, the power capacity would be calculated as follows:

​5.5 watts per foot x 10 feet = 55 watts

+ 20% = 66 watts minimum power supply capacity

​Below is a detailed specification sheet that you can also reference:

​Another thought I had is that the TRIAC dimmable power supply includes a grounded wire which may help with your concerns about a non-grounded power supply unit. These power supplies do not include a plug, however, and will require you to "hard-wire" them to wires in your walls.
