| Note | 1. All parameters are measured at 230V AC input, rated load and 25℃ of ambient temperature if they are NOT specially mentioned. 2. Ripple & noise are measured at 20MHz of 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. Linear adjustment rate test: testing from low vóltage to high voltage at rated load load. 5. Load adjustment rate test: from 0%-100% rated load. 6. The start-up time is measured in the cold start state and the fast and frequent booting and shutting down may increase the startup time. 7. When the altitude is above 2000 meters, the operating temperature should be lowered by 5℃/1000m. |
