I am stuck with a problem. Most switchers are certified to EN 60950-1

 

I require a switch mode PSU certified to EN60335-1.

 

Input 220V ( nominally). Output 15VDC @10Amps.

 

Any recomendations etc welcome.

So this is for an internal PSU as opposed to a wall wart?

Amtex has some supplies that carry that certification.

Yes Brian,

 

Bloody CE certification.

 

Thanks Kartman... have spoken to Amtex.. nothing withthe rating I require.. but are willing to consider searching for a suitable unit.

 

Meanwell distributors wanted to know how many would Sir require before even discussing technical requirement.... SIGH~~~~

 

Still looking. Testing lab  suggested I modify intended Meanwell unit. Add a couple of Y caps and provide certificat of cpapcitor compliance in accordance with...wait...I will remember it....

As that spec is for the final product then any certification of an internal PSU is rather pointless. In fact, given that you can't carry the CE mark from an internal component out to the final product then I can't really see the point. It's not as if that standard is an EMC one either, it's a safety one, so the safety of the unit will depend on how the PSU is integrated.

 

On a practical level, most of the 'electrical' safety standards transfer across to other similar standards. For example, most of 60065 refers to 60950 for the details. I'd be surprised if 60335 doesn't do the same.

 

Were this my problem I'd simply buy a 60950 PSU and in the TCF for the finished article state that as long as that same PSU is used then the overall product conforms to 60335.

 

As for modifying an existing product I can't see that will work as the mods should invalidate the original certification.

Brian thanks on the coment.

 

The power supply which is installed is a 60950 certified unit ( Meanwell 15V 150W and 12V 100W ).

 

I am waiting on some additional input from a supplier of switchers to see if I can change to a happier choice.
