I have a neon sign that uses two power supplies. From the factory, they came wired as one unit with one power cord. When half or one of the power supplies burned out and only half the sign would light, I could not find the tandem style power supply and instead, bought two separate power supplies, replacing the tandem unit. That gave me two power cords to plug in now instead on just the one. I got this and it allowed me to plug both of the new power supplies into it and then have just the one cord to plug into the wall outlet. Made the repair look clean and original and everything is back to normal.
