Range 4.75 ~ 5.5V 10.8 ~ 13.2V 13.5 ~ 16.5V 21.6 ~ 26.4V Output Current 5A 2.1A 1.7A 1.1A Output Power 25W 25.2W 25.5W 26.4W Efficiency (115 VAC) Over Voltage Protection 5.75 ~ 6.75V 13.8 ~ 16.2V 17.25 ~ 20.25V 27.6 ~ 32.4V 72% 76% 77% 80% NOTES 1. All parameters NOT specially mentioned are measured at 230VAC input, rated load, and 25C ambient temperature. 2. Ripple & noise are measured at 20MHz bandwidth by using a 12" twisted pair-wire terminated with a 0.1uF& 47uF parallel capacitor. 3. Tolerance: includes set up tolerance, line regulation, and load regulation. 4. Line Regulation is measured from low line to high line at rated load. 5. Load regulation is measured from 0% to 100% rated load. 6. The power supply is considered a component, which will be installed into final equipment. The final equipment must be re-confirmed that it still meets EMC directives.
