[QUOTE="pwatts, post: 1162703, member: 146"] AC power input and standby power supply is next. Nothing too crazy: an aggressive AC filter for the SMPS standby module powering the main system controller and a mild filter for the 6x linear supplies above. The SMPS is not filtered to have it clean, rather it's done to prevent noise from it and the controller from feeding back into the remainder. So the two sections are separated by one filter each from the mains, and two from each other. A relay to switch power to the linear supplies when in use is triggered with a control signal from the controller PCB. [/QUOTE]
