Effectively, you are applying Criterion A instead of B, and indeed that's usually very difficult to do. That's why Criterion B exists. But there may be no other solution if you buy-in the power supply, unless you can co-operate with the supplier to agree a less stringent requirement that does not result in your own electronics being compromised. -- OOO - Own Opinions Only.
