Notes: 1. Output load regulation is specifi ed for a load change of 20% to 100%. 2. Operation at no-load will not damage these units. However, they may not meet all specifi cations. 3. These converters will operate without external components. However, to meet the specifi ed EMI limits, a simple external input fi lter is required. See the input fi lter note below for more information. 4. All units are rated for operation at full output power to +85° C. Operation over +85°C without airfl ow 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. Model Selection Guide Notes:
- All dimensions are typical in inches (mm)
- Tolerance x.xx = ±0.02 (±0.50)
