Transient voltage is complicated –
protection doesn’t have to be

With the DEHNguard EZ50-S from DEHN, protecting your electrical equipment, systems, and facilities is more convenient than ever before.

What are the electrical threats to your business success?

Transient voltage can originate from various sources, including internal electrical noise, lightning strikes, and utility grid switching. These surges can damage sensitive equipment, disrupt power quality, and jeopardize the safety and efficiency of your operations.

Transient voltage events are inevitable. They strike without warning – posing a significant risk to your critical systems and facilities.

According to industry experts, a single transient surge can exceed nominal system voltage by 5-10 times. Without proper surge protection, these electrical disturbances can cause severe damage, leading to costly repairs, replacements, and operational downtime. 

Protect your business before disaster strikes with the proactive installation of the DEHNguard EZ50-S – a leading surge protection device designed for outdoor applications.
