| Note | 1.All parameters not specially mentioned are measured at 230vAc input,rated current and 25℃of ambient temperature 2. ripple and noise measurement method using a 0.5 - mm twisted pair, and terminal capacitor in parallel with 0.1uF and 47uF, were measured in a 20MHZ bandwidth. 3. safety design of EN60598-1 and EMC, CNS15233, GB700.1, FCC, part18. 4. start time is measured in the cold start, switch frequently may make the starting time of change. 5. the power supply is considered as a component, which is used in conjunction with the terminal equipment. Because the EMC is affected by the whole set of equipment, the terminal equipment manufacturer needs to make a EMC confirmation of the whole set of devices 6. reference Warranty Statement |
