OTHERS

| MTBF| 2418.5K hrs min. Telcordia SR-332 (Bellcore) ; 301.7K hrs min. MIL-HDBK-217F (25℃)
DIMENSION| 4090100mm (WHD)
PACKING| 0.3Kg; 42pcs/13.6Kg/0.82CUFT
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 0.1μF & 47μF parallel capacitor.
3. Tolerance: includes set up tolerance, line regulation, and load regulation.
4. The power supply is considered a component that will be installed into the final equipment. 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 )
5. Length of set up time is measured at first cold start. Turning ON/OFF the power supply may lead to an increase of the set-up time.
6. 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).
