| Note | 1. All parameters, unless otherwise specified, are measured at 230VAC input voltage, rated load and 25°C. 2. Ripple and noise voltages are measured on a 20MHz bandwidth oscilloscope with a 12-inch twisted pair end and a capacitor of 0.1 μand 47 μ. 3. Accuracy: voltage setting error, linear adjustment rate and load adjustment rate. 4. Linear adjustment rate measurement method: under rated load, from low voltage to high voltage test. 5. Load adjustment rate measurement method: from 0% to 100% rated load. 6. The power supply should be considered as part of the components in the system, and the electromagnetic compatibility should be confirmed in conjunction with the terminal equipment. | |||||
