\n
\n\u26a1 Instant Start, When Every Second Counts<\/summary>\n
\n

The TELWIN LEADER 400 START is not just a charger – it is first and foremost a powerful starting tool that delivers an impressive peak current of up to 400 Amperes<\/strong>. This kind of power allows for trouble-free starting of gasoline and diesel engines in a wide range of vehicles: from cars, vans and light trucks to heavy agricultural and construction equipment operating on 12V or 24V systems. <\/p>\n

No more frustration caused by an immobilized vehicle at a critical moment. With the LEADER 400 START, professional garages and mobile services can provide top-quality service, minimizing downtime for their customers’ vehicles. Simple operation and clear ammeter readings make using the start function quick and intuitive, even in a stressful emergency situation. It’s reliability you can rely on when time pressures are at their greatest. <\/p>\n<\/div>\n<\/details>\n

\n\u2699\ufe0f 12\/24V Versatility: One Device, Many Possibilities<\/summary>\n
\n

Flexibility is the key to efficient operation in a modern workshop. The TELWIN LEADER 400 START is designed for maximum versatility, offering the ability to work with both 12V<\/strong> installations, typical of cars and vans, and 24V<\/strong> installations, used in trucks, buses, agricultural and construction machinery. <\/p>\n

This dual compatibility eliminates the need to own and store many different starting devices and chargers. This saves valuable space in the workshop and reduces equipment investment costs. Whether you’re dealing with a small city car or a powerful tractor-trailer, the LEADER 400 START is ready to go, providing the right power and voltage. It’s a smart solution that simplifies logistics and enhances your service capabilities. <\/p>\n<\/div>\n<\/details>\n

\n?\ufe0f Occupational Safety: Protection for You and Equipment<\/summary>\n
\n

Working with electricity always requires caution, and TELWIN knows this very well. That’s why the LEADER 400 START is equipped with a comprehensive safety system<\/strong> that protects both the user and the connected equipment. Key safeguards include overload protection, which prevents damage to the charger in the event of excessive current draw, and pole-swap protection, which eliminates the risk of serious battery and vehicle electronics failure if the terminals are connected by mistake. <\/p>\n

In addition, the device is protected against the effects of short-circuited clamps. These integrated safety systems allow you to work with confidence and peace of mind, even in a dynamic workshop environment. For the professional, this means less risk of costly mistakes, longer equipment life and, most importantly, operator safety. TELWIN is committed to solutions that not only work, but also protect. <\/p>\n<\/div>\n<\/details>\n

\n?\ufe0f TELWIN Reliability: An Investment for Years of Intensive Service<\/summary>\n
\n

For years, the TELWIN brand has been synonymous with Italian quality and reliability in the welding and workshop equipment industry. The LEADER 400 START model continues this tradition, offering a design built for hard, everyday work. The rugged metal housing<\/strong> effectively protects internal components from mechanical damage, dust and dirt typical of the workshop environment. <\/p>\n

A high-quality transformer, heavy-duty wires with the right cross-section, and strong, well-insulated terminals guarantee not only the efficient transmission of current, but also the long life of the entire device. Choosing LEADER 400 START is an investment in a tool that will serve you faultlessly for many years, even with intensive use. It is the assurance that your equipment will not let you down when you need it most. <\/p>\n<\/div>\n<\/details>\n<\/div>\n
