NOTES

1. Transient recovery time is measured to within 1% error band for a step change in output load of 75% to 100%.

2. The ME series requires a minimum output loading to maintain specified regulations. Operation under no-load conditions will not damage

these devices, however they may not meet all listed specifications.

3. All DC/DC converters should be externally fused at the front end for protection.

4. Other input and output voltages may be available, please contact factory.
