Small LED driver to find ?

Soulsurfer · Aug 3, 2017

Long story short, builder I do a fair bit for, in a rush tried fitting some customers light fittings ! Prob caused a dead short and has said breaker tripped but also a pop from luminaire ! Sent me a pic of LED driver that he said had back blown off it ! It seems lower rating than most and I can't seem to source anything similar, going to try wholesalers tomorrow and go try sort his mess out !
It's mains in and secondary is listed 5V DC & 400mA.
Most seem to be standard 10-12V Dc. Any ideas ? He says it's tiny smaller than a match box but if bigger can be hidden above in ceiling. Thanks all

Only RS and mouser but bigger than a matchbox 60.30.22 or 77.40.29. Greater wattage.

Thanks Richard that RS one looks perfect, shame they packed up over here !
I take it the voltage being fine that the wattage etc just needs to be higher than the load requires ? Silly question, sorry

Take away the tax dodges and you lose business!!
So long as the wattage is higher and the voltage the same then it should be fine for a power supply, they usually do not require a minimum load like a transformer.

Excellent, yes tax dodges is bang on over here ha ha, so corrupt the government here !
Just been down to place and besides some capacitive coupling on the strappers the issue was found to be that the builder decided the flexes to £500 + lights needed shortened so did so then in fitting together again took the drivers and having a brown/ blue one side for primary 230V and red /black other side to Led he saw old colour red / black twin at ceiling and decided it must be red /black to same colours and sent mains to secondary on driver ! Brilliant ha ha

He did say when customer popped out that there was a bang and sparks from out ceiling rose & the driver unit and that it blew the back enclosure off too
