Notes | 1. All parameters, unless otherwise specified, are measured at 230VAC voltage input, rated load, and 25 ℃ conditions. 2. Ripple and noise voltage are applied at the end of a 12 inch twisted pair oscilloscope with a bandwidth of 20MHz and an additional 0.1 μ And 47 μ The capacitance is measured at a bandwidth of 20MHZ. 3. Accuracy: including setting error, linear adjustment rate, and load adjustment rate. 4. In the case of low input voltage, it is necessary to derate the output. Please refer to the static characteristic curve for details. 5. The startup time is measured during cold start, and frequent switching on and off may increase the startup time. | |||
