| 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. Tolerance is the sum of voltage setting error, voltage adjustment rate and current adjustment rate. 4. 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. | ||
