Discover the Advanced Features of the TELWIN LEADER 400 START 230V 12-24V
Fast Starting When Every Second Counts
The TELWIN LEADER 400 START is more than a battery charger. Above all, it is a powerful starting tool that delivers an impressive peak current of up to 400 Amperes. That power lets you start petrol and diesel engines without difficulty in a broad variety of vehicles: from cars through vans and light trucks to heavy agricultural and construction equipment running on 12V or 24V systems.
No more frustration with a vehicle stranded at a critical moment. With the LEADER 400 START, professional workshops and mobile service units can offer top-level service and keep their customers' vehicle downtime to a minimum. Simple operation and a clear ammeter reading make the start function quick and intuitive to use, even in a stressful emergency. This is reliability you can count on when time pressure is at its highest.
12/24V Versatility: One Unit, Many Possibilities
Flexibility is the key to efficient work in a modern workshop. The TELWIN LEADER 400 START was designed for maximum versatility and works with both 12V systems, typical of cars and vans, and 24V systems used in trucks, buses and agricultural and construction machinery.
This dual compatibility removes the need to buy and store several different starting units and chargers. You save valuable workshop space and cut your equipment costs. Whether you are dealing with a small city car or a heavy tractor unit, the LEADER 400 START is ready to work and delivers the right power and voltage. It is a smart solution that simplifies logistics and extends your service capabilities.
Safe Operation: Protection for You and Your Equipment
Working with electricity always calls for care, and TELWIN knows this well. That is why the LEADER 400 START comes with a complete protection system that protects both the user and the connected equipment. The key protections are overload protection, which prevents damage to the charger when the current draw is too high, and reverse polarity protection, which removes the risk of serious damage to the battery and vehicle electronics if the clamps are connected the wrong way round.
In addition, the unit is protected against the effects of a short circuit between the clamps. These integrated safety systems let you work with confidence, even in a busy workshop. For a professional, this means a lower risk of costly mistakes, a longer equipment life and, most importantly, operator safety. TELWIN focuses on solutions that not only work but also protect.
TELWIN Build Quality: An Investment for Years of Hard Work
For years, the TELWIN brand has stood for Italian quality and reliability in welding and workshop equipment. The LEADER 400 START continues this tradition with a design made for heavy daily work. A sturdy metal housing effectively protects the internal components against mechanical damage, dust and the dirt typical of a workshop.
A high-quality transformer, heavy-duty cables with a suitable cross-section and strong, well-insulated clamps ensure not only efficient current transfer but also a long service life for the whole unit. Choosing the LEADER 400 START means investing in a tool that will work without failure for many years, even under intensive use. You can be sure your equipment will not let you down when you need it most.
