High-quality products

Research, quality control, and close cooperation with our customers are central aspects of our product development philosophy. Our research and development take place in our own factories, and our products undergo rigorous testing to ensure that they meet the most stringent requirements in the market. This ensures that our products can meet the high demands of our customers in emergency services.

The unique PlugIn connector

The PlugIn connector is the foundation of our system. It is carefully designed to guarantee safe and effective power and to prevents moisture and dirt from infiltrating the connection. Installation is quick, easy and safe – in fact, no license is required to install the system.

An expandable system

The PlugIn system is modular and can be supplemented with additional components if the need arises. Our solution is flexible and future-proof.

Efficient inverters and chargers

An inverter provides access to 230VAC from the battery, making it possible to use or charge electrical equipment in the vehicle. Intelligent battery chargers help maintain battery performance. Our chargers analyze the battery status and provide optimal, temperature adjusted charging curves. Our inverters and chargers are compact as well as water-, dust- and shock-resistant.

Added safety for emergency personel

Our cables are developed with emergency workers in mind. 230V cables are bright orange, making them easier to locate and identify when there is no time to waste.

Accessories for emergency services

The RETTBOX® is an electromagnetic self-ejecting connector system. It consists of a coupler socket and an inlet mounted in a box. When the ignition in the vehicle is turned, a solenoid plunger lifts the socket release latch and ejects the plug from the inlet. This allows rescue workers to save time when the alarm sounds.

For the installer

Quick and easy installation

Choosing a system that is easy to install and that can reliably handle rough environments and heavy loads is a simple way to minimize downtime improve performance. The PlugIn system, helps with both.

Perfect for narrow spaces

Our products are compact and easy to mount, even when space is limited. That makes them ideal for emergency vehicles. Remote panels make installation even more flexible since chargers and inverters don’t have to be easily accessible. Sockets can be installed wherever they are needed.
