Information close
Products that are marked "On Order" in the "Available Quantity" column are usually not in stock. Such products are available for purchase, however, due to their limited customer base, they usually have higher minimum quantities. DACPOL offers products that are not in stock for the following reasons: DACPOL currently has a large number of electronic components in stock and adds new products every day, however, tens of thousands of additional components and their various variants are available from our suppliers. Even though it is unreasonable to have all these products in stock due to the limited sales, we believe that it is in the best interest of our customers to make them available. Our goal is to inform customers about the maximum number of products available and enable them to make decisions based on specifications, prices, availability, required minimums and our technical advice. Please note that selecting the "In Stock" checkbox may limit the display to only products available for delivery straight from the shelf.

DC surge arresters are devices designed to protect DC-powered installations from the effects of lightning and switching overvoltages. They are an important element in securing systems using DC power, such as photovoltaic installations, uninterruptible power supply (UPS), and other DC networks.

Products in this subcategory protect devices from damage and interruptions that can occur as a result of sudden voltage surges or network disruptions. They can increase the reliability of the entire system and minimize the risk of failure of devices sensitive to surges.

Applications

DC surge arresters are used in:

  • photovoltaic installations – to protect solar panels, inverters, and other system components,

  • uninterruptible power supply systems (UPS),

  • overhead lines or other industrial installations using direct current,

  • wherever it is necessary to protect devices against surges in DC systems.

Advantages of use

  • increased safety and reliability installation,

  • reducing the risk of equipment damage and system downtime,

  • compatibility with various types of DC installations,

  • protection against the effects of atmospheric and switching overvoltages.
