The protectors-series SDP-20HP are high performance devices designed to protect sensitive equipment of an installation when we have problems with the electric grid. Transients or voltage surges of high intensity is typically occur on the electrical network due to sudden changes in consumption or other problems of an electrical supply. This generates an overvoltage in the electrical network of high energy that can damage connected equipment. The series SPD-20HP allow us to protect any sensitive electronic equipment like e.g. transformers LED or LED drivers in lighting public or connected equipment in areas with common problems on the electrical network such as industrial estates.

The installation is performed in series with the electric network, equipped with a led indicator of operation visible that notifies us when it is necessary to change the same due to the end-of-life.

For its proper functioning, we must have a good grounding already in case of overvoltage, the excess energy was derived to the earth. We must have an impedance less than 3 ohms to ground to work properly.

This team doesn't protect us in the event of lightning strike directly that can generate a voltage of more than a million volts. For this type of problem, there are protectors specifically for ray.

With plastic housing up to IP66. Series SDP-20HP high performance has a high efficiency designed for applications in road lighting, lighting for outdoor and shopping centres, public lighting, tunnels, lighting of aquariums, digital signage, road lighting, etc, Meets the requirements of UL1449 and EN61643-11.

The temperature protection eliminates any possible problem of fire even in the event that the varistors have reached the end of its life. The protection of these computers is performed by using varistors that are reducing your life according to the number and intensity of the transients. Being able to withstand a transient of 20,000 amps or 1,000,000 transients 240A.

The series SPD offers maximum protection thanks to limits exceptionally accurate and fast voltage transient that can reach the equipment connected to the same.
