Description
This is the APSmart Dual-Core RSD transmitter outdoor kit by APSystems. This is the complete kit including dual core transmitter, power supply, and IP65 latched enclosure. 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: 408005
This 29mm ID dual-core model is suitable for up to 30 PV strings.
