When operating the VHB50, proper derating or cooling is needed. Following is the derating curve of VHB50 without heat sink. V-Infinity, LLC, 20050 SW 112th Ave., Tualatin, OR 97062 www.v-infinity.com 1-866-372-1258 4/4 VHB50 Series Half Brick DC to DC Converter Rev. 06-2006 Remote ON/OFF Control The VHB50 series allows the user to switch the module on and off electronically with the remote on/off feature. The VHB50 series is available with “positive logic” or “negative logic” options. External Output Trimming Output may optionally be externally trimmed (±10%) with a fixed resistor or an external trimpot as shown. Output Noise The output noise is measured with a 10µF tantalum capacitor and a 1.0µF ceramic capacitor across the output.
