| MTBF| 2755.4K hrs min. Telcordia SR-332 (Bellcore) ; 425.8K hrs min. MIL-HDBK-217F (25℃)
DIMENSION| 1999838mm (LWH)
PACKING| 0.7Kg; 20pcs/15Kg/0.85CUFT
NOTE|

All parameters NOT SpECially mentioned are measured at 230VAC Input, rated load and 25 of ambient temperature.
Ripple & noise are measured at 20MHz of bandwidth by using a 12″ twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor.
Tolerance: includes set up tolerance, line regulation and load regulation.(ln order to meet tolerance, it is recommended that CH1 load > 5% rated current.)
Line regulation is measured from low line to high line at rated load.
Load regulation is measured from 20% to 100% rated load, and other output at 60% rated load.
Each output can work within current range. But total output power can’t exceed rated output power.
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 360mm360mm 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)
Length of set up time is measured at cold first start. Turning ON/OFF the power supply very quickly may lead to increase of the set up time.
The ambient temperature derating of 3.5 C/1000m with fanless models and of 5C/1000m with fan models for operating altitude higher than 2000m(6500ft)
