However, sufficient cooling should be provided to help ensure reliable operation of the unit. Heat is removed by conduction, convection, and radiation to the surrounding environment. Proper cooling can be verified by measuring the point as the figure below. The temperature at this location should not exceed 115ºC. When operating, adequate cooling must be provided to maintain the test point temperature at or below 115ºC. Although maximum point temperature of the power modules is 115ºC, you can limit this temperature to a lower value for extremely high reliability. •Thermal test condition with vertical direction by natural convection (20LFM) •The iron base-plate dimension is 19” x 3.5” x 0.063” (The height is EIA standard 2U) •The heat-sink is optional and P/N: 7G-0021A-F, 7G-0022A-F, 7G-0023A-F, 7G-0024A-F |
