All parameters NOT specially mentioned are measured at rated input, rated load and25℃of ambient temperature. 2. Measured at 20MHz of bandwidth by using a12”twisted pair-wire terminated with a 0.1 uF & 10uF 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. We are professional manufacturer engaged in the research, development, production, sale and service of Industrial power supply,We sincerely look forward to cooperating with you and creating the future together!
