Notes & safety
Notes: 1. Heatsink is available for models. To indicate heatsink, add –HS to end of model name.
2. Ripple & Noise measurement with 1µF MLCC and a 10µF tantalum capacitor.
3. Transient recovery time is measured to within 1% error band for a step change in output load of 75% to 100%.
4. Other input and output voltage may be available, please contact factory.
5. To meet EN61000-4-4 & EN61000-4-5 by adding capacitor across the input pins. Suggested Capacitor: 470µF/200V.
6. Parallel capacitor across the input pins under specification testing. Suggested capacitor: 68µF/200V.
7. Natural convection is about 20LFM but is not equal to still air (0 LFM).
*Due to advances in technology, specifications subject to change without notice.
