Q: Checked my cacti this morning and found both of my power supplies have stopped working since yesterday. I have 2 x 50w Cob's on each one in parallel (1 circuit per supply) and both these are connected to switched wall sockets. The socket's are fine but there is next to no power being transferred to the output, when the led's were working they would stay lit for a few seconds after unplugging so there's some issue with not switching the supply off properly (they are grounded so shouldn't behave like that). 3 of the led's have blown and one has 60% of diodes still in tact and glowing very dimly too (about 5w of power). Before i open another ticket is there any simple explanation as to what would cause near total failure of these supplies? Im just glad i checked before any fire's broke out

wujiahui Do not work continuously for too long, if necessary, must strengthen heat dissipation, otherwise it will cause damage to electronic components. AC input: AC110-240V AC frequency: 50Hz / 60Hz Output voltage: DC36V

Q: Can't write this in the relevant answer section but in regard to the 3 x 50w COB Led I've sorted it now thanks, the 2A fuse on the input side had blown, upgraded it to a Schurter 2A cartridge fuse and it works perfectly. 36.2v out.
