Notes:
1. Output load regulation is specified for a load change of 20% to 100%.
2. Operation at no-load will not damage these units. However, they may not meet all specifications.
3. These converters will operate without external components. However, to meet the specified EMI
limits, a simple external input filter is required. See the input filter note below for more information.
4. All units are rated for operation at full output power to +85°C. Operation over +85°C without airflow
is not recommended. Output power should be derated linearly from 100% at 85°C to 0% at 100°C.
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.
