Notes:
1. Output load regulation is specified 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 damage to the
unit.
3. These converters will operate without external components.
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 output units and from
each output to

given in the table above. For applica-
tions requiring very low output noise levels, a simple LC filter
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 float
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.
