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 MM 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.

5.

Heat-sink is optional, please consult factory for ordering details.

Due to advances in technology, specifications subject to change without notice.
