When operating the VHB100W, proper derating or cooling is needed. Following is the derating curve of VHB100W without heat sink. Where: The power dissapation (Pd) is Pd= Pi - Po = Po (1- η )/ η The thermal resistances are listed below. The temperature rise (D T): D T = Pd * Rca V-Infinity, LLC, 20050 SW 112th Ave., Tualatin, OR 97062 www.v-infinity.com 1-866-372-1258 4/4 VHB100W-Q24-S12 DC-DC Converter Rev. 11-2007 Remote On/Off Control The VHB100W series allows the user to switch the module on and off electronically with the remote on/off feature. Logic control defaults to “positive” logic. The diagram shows the recommentded curcuits for positive logic. The “negative logic” option is also available. External Output Trimming Output may optionally be trimmed (±10%) with external fixed resistors or an external trimpot as shown. Output Noise The output noise is measured with a 10uF tantalum capacitor and a 1.0uF ceramic capacitor across the output.
