| Note | 1. All parameters NOT specially mentioned are measured at 12V/24V/48V/96V 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 and 47uf parallel capacitors.
3. Tolerance:includes set up tolerance,line regulation and load regulation.
4. Derating output is required under low input voltage. Please refer to the derating curve for details.
5. The power supply should be considered as a part of the components in the system. All EMC tests will test the test samples on a metal iron plate with a thickness of 1mm, a length of 360mm * width of 360mm. |
