I have a four-rail SR7 that powers several components including a Rubidium master clock, a clock frequency divider, two SOtM EN-to-USB endpoints, and a Merlin BBAM. The SR7 replaced an array of highly filtered, low-impedance SLA batteries. The SR7 is the most strategically important choice in my system. You won’t be disappointed, provided that you can be patient with Paul’s long and sometimes shifting lead times.
Consider his double regulation option for at least one rail.
