Hi,
This is my first post here but I was hoping for some advice.
I am redesigning a power supple for a piece of medical equipment, which is subject to 60601 Pt 1 and Pt 2.2. The transformer is subject to a dielectric stress test of 3kV AC 50Hz.
I am considering using triple insulated wire as this makes construction far easier, and leads to a smaller, more efficient transformer.
The rating of the wire is 700V, which is below the operating voltage of the transformer primary.
The breakdown of the triple insulated wire is said to be 'approx. 700V', however there is no certificating for this. I was considering using the triple insulated wire for primary and secondary, for extra safety.
My question is, is the passing of the dielectric stress test a matter of just passing the test, or must thee material used for the insulation be certified to some recognised standard?
Thanks in advance
Nick
