Converter
An inverter is an essential piece of equipment in the HGV and trailer sector whenever 230V alternating current is needed but only a 12V or 24V DC supply is available. In a truck workshop, during trailer construction, or when carrying out maintenance on a trailer, technicians regularly rely on tools, diagnostic equipment, and electronic devices that are designed for the European mains voltage. An inverter bridges this gap by converting the DC voltage from the vehicle's battery or onboard electrical system into a stable 230V AC supply at 50Hz.
The distinction between a pure sine wave output and a modified sine wave output is critical in professional environments. Frequency converters, variable speed drives, modern switching power supplies, audiovisual systems, and sensitive measuring instruments require a voltage waveform that is equivalent to the public electricity grid. A modified sine wave can cause incorrect operation, overheating, or damage to the internal components of such devices. The inverters in this range deliver exclusively a pure sine wave output, making them compatible with all types of electrical equipment without restriction.
In the daily practice of trailer construction and HGV servicing, this means that a technician or bodybuilder can operate electrically powered tools, digitally controlled welding equipment, diagnostic computers, or laptops without depending on a fixed mains connection. This is particularly relevant when working outdoors, on a yard without fixed power points, or when servicing vehicles that are not positioned near a workshop power supply.
The available continuous power ratings range from 1500W to 3000W, and the appropriate choice depends on the intended application. A 1500W model is sufficient for tools with a modest starting current, measuring instruments, and smaller electric motors. For heavier electric tools such as angle grinders, compressors, or machinery with a high inrush current, a 2000W, 2500W, or 3000W model is more appropriate. It is important to take into account not only the continuous rated power but also the peak power capacity, as the startup current of electric motors can temporarily exceed the continuous rating by a considerable margin.
The choice between a 12V and a 24V input is determined by the electrical system of the vehicle in question. Virtually all heavy commercial vehicles, tractor units, and trailers operate on a 24V onboard system. This offers technical advantages: at equivalent power output, the current draw is lower, resulting in less heat generation and higher conversion efficiency. A 12V inverter is suited to lighter vehicles or specific situations where only a 12V supply is available, such as in certain vans or when operating from a standalone 12V battery.
The inverters in this range are built for professional use in the truck workshop and trailer sector. They incorporate protections against overload, overheating, undervoltage, and short circuit, safeguarding both the inverter itself and the connected equipment. For the trailer builder, HGV workshop, and specialist working on trailers, these inverters provide a dependable means of running 230V equipment wherever a fixed mains supply is not available. They form a functional and practical part of a professional electrical toolkit for the heavy transport industry.
