NOTE: ➀ All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25°C of ambient temperature.

➁ Ripple & noise are measure at 20MHz of bandwidth by using a 10” twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor.

➂ Tolerance: includes set up tolerance, ﬁ re regulation and load regulation.

➃ The power supply is considered a component which will be installed into a ﬁ nal equipment. The ﬁ nal equipment must be reconﬁ rmed that it still

meets EMC directives.
