| MTBF| 964.2K hrs min. Telcordia SR-332 (Bellcore) ; 91.9K hrs min. MIL-HDBK-217F (25℃)
DIMENSION| 85.5125.2128.5mm (WHD)
PACKING| 1.6Kg; 8pcs/13.8Kg/0.9CUFT
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 which will be installed into a final equipment. The final equipment must be re-confirmed that it still meets EMC directives. (as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf )

5. Installation clearances : 40mm on top, 20mm on the bottom, 5mm on the left and right side are recommended when loaded permanently with full power. In case the adjacent device is a heat source, 15mm clearance is recommended.

6. 3 seconds peak power max. and the average output power should not exceed the rate power.

7. Derating may be needed under low input voltage. Please check the derating curve for more details.

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).
