YRSD Modular level PLC type
The YRSD Modular level PLC type is designed to be installed at solar panel level and provides safety shutdown ofthe DC supply to ZERO vOLTS in case of emergency. Shutdown is initiated in 4 ways - Manual Operation, ACSupply Cut-Off or Temperature Rise Trigger sunspec lnverter as follows:
YRSD-1P
when the open-circuit voltage of PV panel is below 120V.
YRSD-2P
when the open-circuit voltage of Pv panel is below 120v.
