1. All parameters NOT specially mentioned are measured at rated input, rated load, and 25°C of ambient temperature
2. Measured at 20MHz of bandwith by using a 12” Twisted pair wire terminated with a 0.1uF & 47uF parallel capacitor
3. The SPS is considered a component which will be installed into final equipment. The equipment must be re-confirmed that it still meets EMC directives.
