| NOTE | 1. All parameters NOT specially mentioned are measured atnormal input, rated load and 25ºC of ambient temperature. 2. Ripple &noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wireterminated with a 0.1uf & 47uf parallel capacitor. 3. Tolerance: includesset up tolerance, line regulation and load regulation. 4. The power supply isconsidered a component which will be installed into final equipment. The finalequipment must be re-confirmed that it still meets EMC directives. | |
