Type Test voltages are not the same as the unit's ratings. If the unit is based on a 1010-1 or 950 standard, the voltage range for Type Tests must be 10% less and 6% greater than the unit's ratings.
The FUS report will not include the unit's Test Report; as an individual FUS report is intended to verify construction only, but the Section General may include production test and other construction requirements. It is not unusual for an unit's markings to indicate a "sub-range" of the safety-agency ratings. Unless the FUS specifically states that the unit will be marked with a specified rating, VNs issued for markings that are within ratings are, IMO, not appropiate. good luck, Brian Hi all, Thank you very much for your comments.I have received many replies from this forum. May be someone out there can standardize this,applicable to UL,TUV,CSA etc. On the report On the physical part VN ? ....................................... ....................................... ..................................................................... 1. Rating (V) 90-135/180-265V 115/230V NO,as this part has been tested in 90-135/180-265V range 2. Rating (I) 12/10A 10A NO,as this rating is within the tested rating 3. Rating (V) 120-127/220-240V 125/230V NO,as this part has been tested in 120-127/220-240V range 4. Rating (V) 120-127/220-240V 120-127V NO,the rating used within the tested range Once again ,thank you all and it would be good if there is standardisation made on this issue.
