After accidentally buying a new red warning light at Holice, I was thinking of replacing it on a weather pole. The original problem was that during the first installation I did not measure the output voltage from the lighting source. Unfortunately, this was somewhere around 15 volts and that led modules did not do well. It was too late when I changed half and lowered the tension. Gradually, half of the modules that had been lit were gone. But I didn't have the power to change the modules again. Well, Holice 2019 was like a gift from pure heaven. I said I bought Indian light at a reasonable price. The price was lower than the postage of Czech Post on delivery, so it was basically decided. The only hitch was that the light is at 48V DC. It's not an unsolvable problem in Holice, just walk and ask. After a while I had a 50V DC switching power supply, something goes missing on the line. After returning from Holice I went to test the source first. Voltage 0. Oh, a blown fuse was a sign of later light effects. After repairing the fuse and plugging the plug into the socket, a blinding flash occurred accompanied by an explosion and subsequent darkness after two circuit breakers were ejected. Is the source operational? My question was. Yes, there is nothing written on it. Thanks guys. Fifty crowns in the basket. So classic, we go looking for a transformer. At the third transformer after rectification and extermination, I achieved exactly 48.1 V DC. And it fixes the fix nicely. I spent a nice morning changing a new pet. Production of a new holder, assembly of the power supply into the box, spraying of the holder and at the end everything is installed and connected. So hopefully they will last a long time. I hope longer than the mentioned functional source.
