Amund, I have to agree with John. If you have a good relationship (and let's not forget YOU are a customer!) with the power supply vendor, you could agree to pay the UL certification fee and have them submit the unit back to UL as an alternate to the original investigation. Based on the proposed changed this SHOULD be a relatively minor task that will involve limited testing.

We purchase a modified power supply (PS) which is not UL appoved. The original PS is UL approved. The only difference in the PS is the value of one resistor which means that we now can take 2.3A/28VDC out instead of 1.9/28VDC. It exist av TUV CB report on the original PS. A local test lab tells us that thay can approve the total IT product (including the PS), but I feel we can get trouble with UL during the audits (4 times a year). Am I right ?
