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 out-

put ripple, it is recommended that

an external ceramic capacitor

be placed from the +Vout pin to

the -Vout pin. An input capacitor

will enhance stability over tem-

perature and input line variations.

Recommended capacitor values

are given in the table above. For

applications requiring very low

output noise levels, a simple LC

filter should be effective.

4. After an output short circuit, the input power must be

recycled to operate the unit.

Tested on X, Y & Z axis for 60 minutes.

6. 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.
