When operating the VHB75, proper derating or cooling is needed. Following is the derating curve of VHB75 without heat sink. Where: The power dissap ation (Pd) is Pd= Pi - Po = Po (1- η )/ η The thermal resist ances are listed below . The temperature rise ( D T): D T = Pd * Rca

Output Noise The output noise is measured with a 10uF t ant alum cap acitor and a 1.0uF ceramic cap acitor across the output. Remote On/Off Control The VHB75 series allows the user to switch the module on and of f electronically with the remote on/of f feature. Logic control default s to “positive” logic. The diagram shows the recomment ded curcuit s for positive logic. The “negative logic” option is also available.
