⚡ Static Transfer Switches (Static Transfer Switch STS <4.0ms Sub-Cycle SCR Phase Transfer)

Solid-State Static Transfer Switch (STS) Calculator

Size high-speed Solid-State Static Transfer Switches (STS / Cyberex / Eaton / Vertiv) utilizing back-to-back Silicon Controlled Rectifiers (SCR): achieve ultra-fast sub-cycle transfer times ($<4.0 ext{ milliseconds}$) between unsynchronized A and B power sources without server power supply dropped cycles, and power reliability yields.
