As a result, customers choose our products for the most demanding applications, such as in emergency vehicles.

The unique PlugIn connector

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

An expandable system

The PlugIn system is modular and can be supplemented with additional components if the need arises. Simple and safe PlugIn connections also makes it easy to upgrade or replace components. This means that you get a future proof system that you can adapt to changed requirements.

Intelligent chargers

Intelligent battery chargers help maintain battery performance. Our chargers analyze the batteries and provide optimal, temperature adjusted charging curves. This extends battery lifetimes and minimizes waste. Our chargers are compact and water, dust and shock-resistant.

Highly efficient inverters

An inverter provides access to 230VAC on the truck, making it possible to charge or operate most types of electrical equipment. Our inverters meet the highest standards of quality and safety. They are designed to withstand heavy use and provide the best possible voltage at all times. You can expand the system with several outlets at any time.

For the installer

Quick and easy installation

It is essential to choose a system that is easy to install, and that can handle rough environments and heavy loads. The PlugIn system, in combination with a large selection of cables and connectors, provides both. Smart connections mean that no license is required to make the installation.

Our products are compact and easy to mount, even when space is limited. Remote panels make the installation flexible since components don’t need to be accessible for the user.

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
