NOTE | 1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25°C 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 directive. | ||
5. Dearating may be needed under low input voltage. Please check the derating curve for more details. | ||
