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 specifica-

tions, a minimum load of 25% 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.

Model Number

For the alternate pin-out (see page 4) , add suffix “P2” to model number

(i.e. MA524S-05RWI-P2)
