NOTE
DIMENSION PACKING
1. All parameters NOT specially mentioned are measured at 12, 48VDC input, rated load and 25 of ambient temperature. 2. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor. 3. Tolerance : includes set up tolerance, line regulation and load regulation. 4. The power supply is considered a component which will be installed into a final equipment. The final equipment must be re-confirmed that it still meets EMC directives. 5. For the input line, a 47uF/100V electrolytic capacitor with Esr<1 is used in the test. 6.EMC filter suggestion(TBD):
