Hello. I’ve purchased a 6 zone Konnected board with the uninterruptable power supply. I’m replacing an old Gardtec 300 panel that takes the 230v uk supply through a transformer in the Gardtec box. As the Gardtec board has 12v text on it i assumed the transformer must be converting the power to 12v DC. I therefore connected a plug directly to the wires from the transformer and connected to the battery pack.
Both lights on the battery illuminated and then swiftly went out and the fuse just off the mains supply blew.
What am indoing wrong? Am i wrong about the transformers supply? Is there an alternative transformer that i could use as theres no power socket in the cupboard.
Well, you’ve got mains power on one side of the transformer, so you could always remove everything from the panel and use that.
However, the transformer is generating AC – probably a higher voltage than 12V (18V or so is typical) which is then regulated and converted to AC by the circuitry on the board. You probably have 12V DC available from the board where it charges its own battery, and likely at a few other points.
Given what you’ve described, you should replace its fuse and spend some time with a multimeter.
Thanks for your response. We had the same thpught, i decided to take the mains power and install a socket in the cupboard so i can just use the provided power supply and not bother with the old transformer.
