MIL-HDBK-217F (25 ) OTHERS DIMENSION 107*61*28mm (L*W*H) 0.13Kg; 96pcs/15.4Kg/1.3CUFT PACKING 1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25 of ambient temperature. NOTE 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.
