I am currently having difficulty understanding the operation of this circuit. From my understanding the Zener diode provides a 5.1V voltage drop resulting in VRz = (400-5.1) = 394.9V. Meaning the OPAMPs + rail is 400V and the - 349.9V how does this supply the device, my intial thoughts are it takes the potential difference of the to rails (v+ - v-) = 5.1V but is this correct ?
