(0.88Kgs) UL1950, TUV EN60950 CISPR22 (EN55022) CLASS B, IEC801-2,3,4, IEC555-2 verification 1. All parameters are specified at 230VAC input, rated load, 25°C 70% ambient 2. Tolerance includes set up tolerance, line regulation, load regulation 3. Ripple & noise are measured at 20MHz by using a 12” twisted pair terminated with a 0.1uF & 47 uF capacitor 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. Each output provides up to maximum current, but total load can not exceed max. output power 7. C2, C3, C11 must be removed *V-Infinity reserves the right to make changes to its products or to discontinue any product or service without notice, and to advise customers to verify the most up-to-date product information before placing orders.
