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. Derating may be needed under low input voltages. Please check the derating curve for more details.
5. There is high possibility to trigger the floating over voltage protection when PV voltage is trimmed from a high voltage level to a lower voltage level at light
load or no load condition. It is suggested that turn off the power supply and set PV voltage to the lowest level, then adjust output voltage to a desired value.
6. Strongly recommended that external output capacitance should not exceed 5000uF. (Only for: RSP-750-5)
7. The power supply is considered a component which will be installed into a final equipment. All the EMC tests are been executed by mounting the unit on
a 720mm*360mm metal plate with 1mm of thickness. The final equipment must be re-confirmed that it still meets EMC directives. For guidance on how to
perform these EMC tests, please refer to EMI testing of component power supplies. (as available on http://www.meanwell.com)
8. The ambient temperature derating of 3.5
℃
/1000m with fanless models and of 5
℃
/1000m with fan models for operating altitude higher than 2000m(6500ft).
