| Note | 1. All parameters are the measured values under the conditions of 230VAC input voltage, rated load and 25°C. 2. Ripple and noise measurement methods: use a 12 ‘twisted pair, and a terminal to parallel 0.1 uf and 47 uf capacitance, measured in 20 MHZ bandwidth. 3. Voltage adjustment is limited to the input range of 220 to 264VAC. Any voltage adjustment outside this range may cause abnormal output. 4. Accuracy: Includes setting error, linear adjustment rate and load adjustment rate. 5. In the case of low input voltage, the output needs to be reduced. Please refer to the static curve for details. 6. The power supply shall be deemed to be part of the system components, emc related validation should be carried out combined with terminal equipment. | |||
