5 Strings RSD Fast Shutdown Device

YRO string level quick shutdown device focuses on controlling 5 such PV strings at the same time. When encountering situations such as fire, system failure, daily maintenance, etc., it is able to quickly disconnect the corresponding 5 PV strings from external circuits, based on various shutdown commands received (which can be triggered manually by human hands, or by commands issued by the automatic judgment of the monitoring system), and prevent further transmission of electric current to avoid the problems caused by live operation and so on. This prevents the risk of electric shock due to electrified operation, and ensures the safety of personnel and the stable operation of the entire PV power plant.

The YRO 5 Strings RSD Fast Shutdown Device in startup performance. It innovatively adopts an external power supply mode. This design enables it to be completely independent of components during the startup process. That is to say, as long as the power grid remains energized, the RSD can start up quickly and enter the working state, promptly playing its crucial role of rapid shutdown, and providing a strong guarantee for the safe and stable operation of the entire system.

YRO quick shutdown equipment is wall mounted, this wall mounted design has been carefully considered, fully integrated with the structural characteristics of the product and the needs of the actual application scenarios, to ensure that the equipment can operate stably and reliably after wall mounting, and at the same time, it is also easy to install the layout of the installation in all kinds of places. Whether it is in the indoor electrical equipment room, or outdoor near the distribution box, wall mounted installation can make it fit perfectly with the surrounding environment. While saving space, it can effectively guarantee the normal operation of the equipment, as well as the safety and stability of the whole power system, providing users with a more efficient, convenient and safe power protection program.
