NOTES

1. These power converters require a minimum output loading to maintain all specified regulations. Operation under no-load conditions will not

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

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

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