Test conditions and notes8

1. All parameters NOT specifically 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. NMP650: The efficiency changes by installing different output modules. The following combination is chosen when fitting different types of module: 5V (Voltage code C)*1, 12V (Voltage code E)*1, 24V (Voltage code H)*1, 48V (Voltage code K)*1. (650W max.) NMP1K2: The efficiency changes by installing different output modules. The following combination is chosen when fitting different types of module: 5V (Voltage code C)*1, 12V (Voltage code E)*1, 24V (Voltage code H)*2, 48V (Voltage code K)*2. (1200W max.) The hold up time of the combination above is 16ms/230vac @ 75% total output power、10ms/230VAC @ total output power.
5. The power supply is considered a component which will be installed into a final equipment. All the EMC tests have been executed by mounting the unit on a 360mm*720mm 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 https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf)
6. De-rating may be needed under low input voltages. Please check the derating curve for more details.
7. Under parallel operation ripple of the output voltage may be higher than the SPEC at light load condition.
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).
