| Note | 1. Unless otherwise specified, all specifications are measured under the input of 230VAC, rated load, and ambient temperature of 25℃. 2. Measurement method for ripple and noise: use a 12″ twisted pair cable, and terminals must be parallel with 0.1uf and 47uf capacitors at 20MHZ bandwidth. 3. Accuracy: includes setting error, linear regulation rate, and load regulation rate. 4. Measurement method for linear regulation rate: test from low voltage to high voltage at rated load. 5. Measurement method for load regulation rate: from 0% to 100% rated load. 6. The power supply should be considered as part of the system components and needs to be confirmed for electromagnetic compatibility related issues when combined with the end equipment. | ||
