SEL-3505 RTAC

SEL-3505 RTAC

The SEL 3505 is the newest, and low-end version of the RTAC. It supports Modbus, DNP3, IEC 61950, and GOOSE protocols but supports fewer points and interfaces. It does not support built-in HMI. Because it supports control programming, Affinity Energy is using it for curtailment control at small solar sites to manage plant output.
