Surge protective decives, also known as lightning arresters, are electronic device that provide safety protection for various electronic equipment, instrumentation, and communication lines. When a surge current or voltage is suddenly generated in an electrical circuit or communication lines due to external interference, thesurge protective decives can conduct the shunt in a very short period of time, thereby avoiding the damage of the surge to other equipment in the circuit. The surge protective decives are suitable for the requirements of surge protection in domestic residential, tertiary industry and industrial fields. The followings are the features of surge protective decives.
1. The protection flow of the surge protective decives is large, the residual pressure is extremely low, and the response time is fast.
2. The surge protective decives adopt the latest arc extinguishing technology to completely avoid fire.
3. The surge protective decives adopt temperature control protection circuit and built-in thermal protection.
4. The surge protective deciveshave power status indicators to indicate the working state of the surge protectors.
5. The surge protective decives have rigorous structure and stable and reliable performance.
Surge protective devices are crucial components of any electrical installation. They play a vital role in protecting your devices and equipment from voltage spikes and surges. But what are they exactly? In this blog post, we’ll take a closer look at surge protective devices and why they are essential for your home or business. […]
To protect an electrical installation in a building, simple rules apply for the choice of 1. SPD(s); 2. its protection system. For a power distribution system, the main characteristics used to define the lightning protection system and select a SPD to protect an electrical installation in a building are: 1. SPD 1.1 quantity of SPD 1.2 type 1.3level of exposure […]
DC Surge protective device,protect against lightning surge voltages in solar system (photovoltaic power supply system). These units must be installed in parallel on the DC networks to be protected and provide common and different modes protection. Its installed location are recommended at both ends of the DC power supply line (solar panel side and incerter/converter […]
