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.

Recommended component values are shown in the table at right. Capacitor C 1 is a 1210, 100V/ceramic, except for the 48V input which is a 100V/electrolytic. Capacitor C 2 is a 1210 100V/ceramic. Capacitor C 3 is a 1206 2 kV/ceramic. To meet the requirements of EN 61000-4-4 and EN 61000-4-5, the value of capacitor C1 should be changed to 470 µF/100V. All components should be mounted as c lose to the unit as possible. For 48VDC input models the width of the unit is 0.29 (7.5) and the pins are set 0.08 (2.0) from the edge of the case. These dimensions are identifi ed with an “*” on the mechanical drawing
