NOTE:(1)
All measurements are at nominal input, full load and +25°C unless otherwise specified.
(2) Line Regulation measured from High to Low Lines at full load.
(3) Load Regulation measured from Full Load (F-L) to Half-Load (H-L) at nominal input.
(4) Correct fuse size by calculating the max. DC current drains at low Line input & Load and then adding 20-25% for the desired fuse size.
Due to requests in market and advances in technology, specifications subject to change without notice.
