APSystems APsmart RSD-D-15 PV Module Rapid Shutdown Device

APSystems APsmart RSD-D-15 PV Module Rapid Shutdown Device

RSD-D meets SunSpec requirements, maintaining normal function by continually receiving a heartbeat signal from the APsmart Transmitter. The RSD-D executes rapid system shutdown when the Transmitter signal is absent. Users can manually execute rapid shutdown using Transmitter breaker switch.

RSD units automatically enter rapid shutdown mode when the Transmitter-PLC is switched off and resume energy production when power is restored to the Transmitter-PLC. This solution complies with NEC 690.12 specifications for 2017&2020 and supports the SunSpec signaling for rapid shutdown

Product Specifications:
