Table 4-18 UL 1950 Over-Voltage Test
Notes:
1. If the equipment design uses a voltage limiter designed to breakdown at a level of greater than 285V
PK
, then
a voltage below this level is to be used during this test.
2. As an alternative test procedure, where a fuse causes an open circuit during test, the fuse may be
bypassed and the available short circuit current applied set to 135% of the fuse rating.
