An input line fuse must always be used. This encapsulated power module can be used in a wide variety of applications, ranging from simple stand-alone operation to an integrated part of sophisticated power architecture. To maximum flexibility, internal fusing is not included; however, to achieve maximum safety and system protection, always use an input line fuse. Suggested input line fuses are below: Model Fuse Rating Fuse Type 12VDC nominal input models 25A Fast-Acting 24VDC nominal input models 12A Fast-Acting 48VDC nominal input models 8A Fast-Acting THERMAL CONSIDERATIONS This power module operates in a variety of thermal environments. 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 in the figure below. The temperature at this location should not exceed 105ºC. When operating, adequate cooling must be provided to maintain the test point temperature at or below 105ºC. Although the maximum point temperature of the power modules is 105ºC, 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-0029B-F, 7G-0030B-F, 7G-031B-F, 7G-0032B-F BASE PLATE MODEL NUMBER SETUP DCQA 150 - 48 S 05 R H (1) Series Name Output Power Input Voltage Output Quantity Output Voltage Remote ON/OFF Hole Thread & Heatsink Options 150: 150 Watts 12: 8.5~22 VDC S: Single Output 33: 3.3 VDC None: Positive Logic None: M3x0.5 Threaded-thru Inserts 24: 16.5~36 VDC 05: 5 VDC R: Negative Logic TH: Ø.126 Thru-hole Inserts (1) 48: 33~75 VDC 12: 12 VDC H: 0.24” Horizontal Heatsink 15: 15 VDC H1: 0.5” Horizontal Heatsink 24: 24 VDC H2: 0.24” Vertical Heatsink 30: 30 VDC H3: 0.5” Vertical Heatsink 48: 48 VDC (1) Models with thru-hole inserts cannot be equipped with a heatsink. |
