I. Basic Introduction to Surge Protective Devices (SPDs):
1.The HD-EPP series high-energy power SPDs consist of multiple single-plate spark gap modules. Depending on the specific requirements of different power distribution systems, they can be flexibly combined for either single-phase or three-phase protection, effectively preventing damage to low-voltage electrical equipment caused by induced or switching overvoltages.
2.Oumaan's lightning protection series products are safe, reliable, and easy to wire and install. Featuring a highly efficient "surface discharge spark gap," they offer exceptional lightning current discharge capacity. Additionally, their follow-current suppression capability ensures they meet the stringent requirements of highly reliable and stable systems.
II. HDS-D20 Surge Protective Device (Class D)
1.Product Introduction
The HDS-D20 surge protective device is designed according to IEC 61643 and GB 18802 requirements. Suitable for low-voltage power supply systems of 48-62Hz, it is a voltage-limiting type surge protective device. The product has been tested and complies with IEC 61643-1 and GB 18802.1 requirements. The product class is Class D.
2.Product Advantages
The significant features of this product are low output residual voltage and fast response time. Especially when a lightning surge passes through the protector, no follow current will occur. In the event that the lightning arrester fails due to overheating, overcurrent, or breakdown caused by a lightning strike, the built-in failure tripping device can automatically disconnect it from the power grid.
3.Scope of Application
The HDS-D20 is suitable for induced lightning protection of sensitive electronic equipment inside buildings. It can serve as a Class III (Type 3) power line surge protective device within a building, and is installed in the sub-distribution cabinet at the boundary between LPZ2 and LPZ3 zones inside the building.
III. HDS-C40 Surge Protective Device (Class C)
1.Product Introduction
