Notes:
Derating Curve
1. Transient recovery is measured to within a 1% error band for a load
step change of 75% to 100%.
2. Output load regulation is specified for a load change of 25% to
100%.
3. 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.
4. These units should not be operated with a load under 10% of full load.
Operation at no-load may cause damage to the unit.
5. These converters are specified for operation without external com-
ponents. However, in some applications the addition of input/ouput
capacitors will enhance stability and reduce output ripple. Recom-
mended capacitor values are:

For applications requiring very low output noise levels, a simple LC
filter should be effective.
Mechanical Dimensions
6. Dual output units may be connected to provide a 10V, 24V or 30 VDC
output. To do this, connect the load across the positive (+Vout) and
negative (-Vout) outputs and float the output common.
7. 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.
