| NOTE | ||||||
| 1. All parameters NOT specially mentioned are measured at 230VAC 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 final equipment. The final equipment must be re-confirmed that it still meets EMC directives. | ||||||
