EWIMAR – effective surge protection based on knowledge, standards, and flexible solutions

Modern security systems, LANs, IP surveillance, and industrial infrastructure are getting increasingly vulnerable to the effects of surges caused by lightning strikes, power grid interference, and potential differences. This is due to the miniaturization of electronic components; even a short surge can lead to device damage, system downtime, and costly repairs.

EWIMAR has specialized in the design and manufacture of surge arresters for CCTV, LAN, and industrial automation systems for 15 years. Our solutions are designed for installers and end users who expect not only high protection effectiveness but, above all, system stability.

Our products are designed to meet the PN-EN 61643-21 standard, allowing them to be used in LPZ 0/LPZ 1 zones and higher – those are defined by the EN-62305 standard.

Our product range includes surge arresters for CCTV (VSS) systems. It has been divided into three product series: ECO, PRO, and EXT, which allow for the optimal selection of protection levels for specific installations. The ECO series is designed for indoor applications with a lower risk level. The PRO series is a solution for professional outdoor installations requiring a higher level of surge immunity. It features two levels of surge suppression, along with protection against surges on PoE pairs, in any power supply standard. The protection level is 2.5kA (8/20 μs) per conductor. The EXT series, in addition to the components used in the PRO series, features an additional level of protection in the form of ultra-fast MOSFET fuses with automatic reset. The MOSFET fuse reduces surge voltage levels and extends the life of the surge arrester. The protection level is 2.5kA (8/20 μs) per conductor.

The core of our offer is single-channel protection in various housing variants. Depending on the intended use, they are available for mounting in camera boxes, on DIN rails, and in hermetic enclosures. To achieve full protection, the other side of the signal line must also be protected. For this purpose, we have designed 4-channel modules, which, together with a 1U housing for a 19″ rack, create an integrated multi-channel panel. This approach allows for flexible and optimal selection of the protection level to suit the installation’s needs.

Thanks to our solutions, installers can build a security system precisely according to the project’s needs – from single security elements to complex multi-port systems. Modules can be easily replaced, expanded, and serviced without having to disrupt the entire installation.

Solutions dedicated to various communication buses are also very popular in our product lineup. In addition to surge protectors for the RS-485 bus, customers are also gladly choosing PTZ protocol converters. These products enable the integration of legacy CCTV systems with modern devices.
