Notes:
1. When measuring output ripple, it is recommended that an external ceramic
capacitor (approx approx 1 µF to 10 µF) be placed from the +Vout pin to the
-Vout pin for single output units and from each output to common for dual
output units.
2. These units should not be operated with a load under 10% of full load. Opera-
tion at no-load
may cause damage to the unit.
3. These converters are specified for operation without external components.
However, in some applications the addition of input/ouput capacitors will
enhance stability and reduce output ripple. Recommended capacitor values
are:

For applications requiring very low output noise levels, a simple LC filter should
be effective.
4. Dual output units may be connected to provide
a 10V, 24V, 30V or 48 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.
