OJS-SA

SERIES

Dimension: W36×L78×H22mm

*1 cold start

*2 at DC130V input, 25C and rated output

*3 measured by a bayonet probe at the output connector at a 0 to 100MHz bandwidth

*4 at -10 to +71C

*5 only for 7hours from 1hour after switch-on at 25°C and rated input/output

*6 when output current changed rapidly between 25% and 75% of rated current at rated input

*7 only for a limited time of over current
