Notes:

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:

48 VDC

100 µF per 1A of Iout

For applications requiring very low output noise levels, a simple LC

filter should be effective.

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.
