Description

APSmart Single-Core RSD Transmitter by APSystems. This SunSpec Certified device sends a ‘keep alive’ signal through your DC solar array cables. When proper voltage is not detected the Transmitter stops sending the keep-alive signal to the RSD device, initiating module-level rapid shutdown sequence.

For SunSpec compliance, pair this transmitter with the APSmart PLC receivers (single or dual module versions) which get placed on the back of your solar modules. The system maintains constant communication between the RSD and Transmitter-PLC, constantly monitoring voltage and current.

Model: 406001
This 29mm ID single-core model is suitable for up to 15 PV strings.
