AC-DC SURGE ARRESTER (SPD)

In new generation surge arresters, AC-DC surge arresters are now produced as a single product on the same board!

The use of surge arresters in low voltage systems is increasing day by day.

Although surge arresters, which generally have foreign-based production origins, are designed to prevent electronic boards from burning out, they could not fully prevent damage due to their dependence on grounding resistance and systemic peaks created particularly by boards operating in DC.

There are generally two main reasons why surge arresters fail to prevent electronic board errors and damages as a whole:

• The need for good grounding,
• Systemic peaks in DC boards

New generation surge arresters primarily eliminate the need for good grounding and perform their protection function perfectly even if there is no grounding at all; and now, by producing DC surge arresters on the same board as AC surge arresters, they have succeeded in reducing the protection capability down to the capillary lines.

Trimbox, which produces two-pole, four-pole, 110V, 220V, 380V, 490V models in AC surge arrester production with the new generation surge arrester, was also producing between 12V-1500V in DC surge arresters.

The AC-DC surge arrester, which appears as a systemic necessity especially in rectifiers within telecom and distribution company panels, will demonstrate its difference in international surge arrester markets in the near future.

Simple precautions sometimes save lives. The best investment we can make for our family, our business, and our environment is protective measures. With Trimbox and GNDSeries, you can be protected from electricity-related damages and electrical contact fires caused by them.
