Product Introduction
In the context of the growing solar sector where electrical safety has become a critical priority, YRO developed its module level rapid shutdown. This product delivers a robust and reliable circuit protection mechanism for photovoltaic systems. Certified under UL3741 standards, it ensures compliance with international safety regulations, enabling immediate and accurate power disconnection during system failures or emergency scenarios. This technology effectively reduces risks of thermal incidents, electrical accidents, and related hazards.
Product Description
Specifically devised for photovoltaic applications, this rapid shutdown device is eminently suitable for utilization in diverse outdoor settings. Boasting IP68 level protection, it can efficiently shield against moisture and dust ingress. This ensures that the equipment sustains high efficiency and stability even in humid, dusty, or extreme weather conditions. Such a design empowers it to be deployed across a broad spectrum of harsh environments, adapting to the ever changing environmental demands on a daily basis and facilitating long term system operation.
YRO’s component level quick shutdown devices are fabricated with top grade materials, which endow them with durability and corrosion resistance. Irrespective of whether it is in high temperature, high humidity, or low temperature environments, these devices consistently offer enduring and trustworthy protection. The RSD eschew reliance on complex intelligent features, which streamlines the system architecture and minimizes potential failure points, rendering device operation more straightforward and reliable.
For solar photovoltaic systems, system safety assumes the utmost significance, particularly when an electrical failure occurs. YRO devices preempt electrical accidents at the root by employing a highly accurate shutdown mechanism, that severs the current within an extremely short time frame. This not only safeguards the equipment but also averts the risk of injuries, fatalities, and property damage.
