DC module-level electronics

APsmart is a new brand of DC module-level electronics, including the RSD (Rapid Shutdown Device) and Transmitter-PLC for enabling rapid shutdown compliance at a solar site. Certified to SunSpec and NEC 690.12 Rapid Shutdown requirements, the RSD and Transmitter-PLC offer built-in safety, reliable technology, and are a rapid shutdown compliance solution. The APsmart RSD System is a SunSpec Alliance Certified [paired] device which maintains constant communication between the RSD and the Transmitter, constantly monitoring voltage and current. When proper voltage is not detected, the Transmitter stops sending the keep-alive signal to the RSD-S-PLC device, immediately initiating the module-level rapid shutdown sequence.
