Notes:
Derating Curve
1. Output load regulation is specified for a load change of 10% to 100%.
2. Operation at no load will not damage these units, however, they may not meet all specifications.
3. These converters are specified for operation without external components. However, in some applications the addition of
input/output capacitors will enhance stability and reduce output ripple.The simple connection shown below will typically
meet EN 55022 Class B. For dual output units, a capacitor should be connected from each output to common.
4. 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.
