Please, let me use a few sentence to introduce this case: We are manufacturing a radio device which is powered by 28VDC. For the EU region, we fulfill EMC, LVD and RTTE. Since we may sell this device outside EU, we will go for a CB test report / certificate. The radio device will be sold by a standalone AC/DC adapter, which is bought from an external power supply dealer. Today, we have picked 4 potential adapter that fits good to our equipment and they all have CB certicicates and UL listed. The radio device have an enclosure of HB material and that means we have to select adapters which is classified as "limited current source" ref. chapter 2.5 in IEC60950:1999. Note: Tha adapter is not included in the radio device, it is a seperate unit.
Question: We have asked for a CB test report / certificate for our radio device. The cert. body have told us that the adapters have to be listed in the CB report. Is that correct ? If so, I may be stucked with these 4 adapters into the future and if we find a new type that is much cheapter and holds the same approvals / specs, do we have to ask for a revised CB report ? Could the CB body in general terms state in the report that " ....the radio devive must be powered by an adapter what is a limited current source, holds a CB certificate, etc ...."?
