| Remarks | 1. Unless otherwise specified, all parameters are the measured values under the conditions of 400VAC input voltage, rated load and 25°C. 2. The ripple and noise voltages were measured with a 20MHz bandwidth oscilloscope at the end of a 12-inch twisted pair cable with 0.1μ and 47μ capacitors. 3. Accuracy: includes set error, linear adjustment rate and load adjustment rate. 4. The power supply is regarded as an independent component, but the final power supply still needs to be confirmed for electromagnetic compatibility in combination with the terminal equipment. | |||
