Real-Time Automation Controller (RTAC)

The SEL-3530 1U and 3U form factors are no longer in production, but SEL will continue to support and warranty these units. In their place, SEL recommends selecting the SEL-3350 RTAC, which offers greater processing power and enhanced features in the same form factors.

Replacement product: SEL-3350

SEL still offers the SEL-3530-4 1U half-rack form factor.
