Notes:
1. Output load regulation is specifi ed for a load change of
10% to 100%.
2. These units should not be operated with a load under
10% of full load. Operation at no-load may cause dam-
age to the unit.
3. These converters will operate without external com-
ponents. However, when measuring output ripple, it
is recommended that an external ceramic capacitor be
placed from the +Vout pin to the -Vout pin for single out-
put units and
from each
output to
common for
dual output
units. An in-
put capacitor will enhance stability
over temperature and input line
variations. Recommended capaci-
tor values are given in the table above. For applications
requiring very low output noise levels, a simple LC fi lter
should be effective.
4. Dual output units may be connected to provide a 10V,
18V, 24V or 30 VDC output. To do this, connect the load
across the positive (+Vout) and negative (-Vout) outputs
and fl oat the output common
5. It is recommended that a fuse be used on the input of
a power supply for protection. See the Model Selection
table above for the correct rating.
