Model Selection Guide

Notes:

1. Cross regulation is measured with the output being tested at 100% load while

the other output is varied from 25% to 100% load.

2. See the typical connection circuit on page three for typical external filtering components.

For help with a specific model or layout issue, contact the factory.

3. Isolation voltage is specified for Input to output. On units with the optional metal case,

the isolation voltage for Input - Case and Output - Case is 1,000 VDC.

4. Operation at no-load will not damage the unit, but they may not meet all specifications.

To meet all specifications, a minimum load of 33% should be maintained.

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.
