Raycap introduced ProBloc B 1000 DC, a new overvoltage protection solution for DC applications. With this new solution, a large number of DC charging stations can be safely protected with this product. Rectifiers and converters aim to operate with as little loss as possible. However, these components
“Both rectifiers and inverters must convert voltages with minimal loss. However, since these components react very sensitively to overvoltages, they must also be protected with suitable protective elements.”
Electric vehicle charging stations and energy storage systems frequently use technologies such as fast charging or battery storage systems, especially in DC applications. These battery-related technologies require high-level protection solutions.
Unlike AC voltage, DC voltage has no zero crossing, therefore the resulting electric arcs cannot be extinguished automatically. As a result, fires can easily start.
With the new ProBloc B 1000 DC (Raycap, UL Type 2 CA certified), we offer a future-proof product for a wide range of DC sources. Its key features include a compact design and a unique patented disconnecting device with a rotating mechanism capable of safely extinguishing switching arcs. Thanks to its high self-extinguishing capability, a possible short-circuit current of 50 kA can be disconnected, as in storage systems.
Due to the combination of Type 1 and Type 2 arresters, our new surge arrester series can be used for lightning or overvoltage protection in electric vehicle charging stations and energy storage system applications.
In addition, ProBloc B 1000 DC provides continuous operating voltage up to 1000 V. Raycap recommends using an arrester without leakage current as a way to ensure that insulation monitoring is not disrupted. The new product also prevents leakage current.
The protection level Up < 2.3 kV also ensures the protection of a charging electric vehicle. Vehicles with such drives require a nominal voltage of 2.5 kV. Therefore, if the correct connection is made, the surge arrester also protects the electric vehicle being charged. The color display provides clear information about the status of the product, and integrated telecommunication communication enables remote monitoring of the product… In a warning issued by Yılkomer General Manager Serdar Aksoy; “For long-term investment sustainability and to prevent damage to charged systems, DC system protection must be used in charging stations and energy storage systems. In this regard, we recommend Raycap PROBLOC B 1000V DC, which features the latest technology for DC systems up to 1000 V, to all our customers!” He emphasized the importance of the issue. Looking at the features of the PROBLOC B 1000V DC product, which has started to be used in many applications worldwide; *It has a compact design *It operates up to 1000 V DC *Provides 20 kA protection at 8/20 µs *Has 6.25 kA impulse current protection *Features a new patented rotating mechanism to safely extinguish switching arcs For more detailed information about the product, you can contact us via info@yilkomer.com.
