All specifications were measured at rated input, rated load, and 25°C ambient temperature. Ripple noise test method: Use a 12# twisted-pair cable, with 0.1uF and 10uF capacitors connected in parallel at the termination. Measure using an oscilloscope with a 20MHz bandwidth. The power supply will be installed as a component in the final device, which must still meet EMC requirements.
