Pulse Tronic: a smart revolution in battery care
Pulse Tronic technology, the core of the TELWIN T-CHARGE 20 charger, is much more than standard charging. It is an advanced, 8-phase, fully automated process that precisely manages every stage in the life of your battery. As soon as it is connected, the T-CHARGE 20 starts with a diagnosis (CHECK), verifying the battery condition and its ability to accept a charge. Then, if necessary, it runs the desulphation (DESULPHATION) phase, breaking down the lead sulphate crystals that limit battery capacity and service life.
The next stages are main charging (BULK) at maximum current until about 80% of capacity is reached, followed by the absorption (ABSORPTION) phase, in which the current is gradually reduced so that the battery is safely topped up to 100% without the risk of overcharging. Once the battery is fully charged, the unit switches to analysis (ANALYSE) mode and checks whether the battery holds its charge. If everything is in order, the smart pulse maintenance (FLOAT/PULSE) mode is activated, keeping the battery at an optimal state of charge for a long time, compensating for self-discharge and preventing sulphation. For a professional this means certainty that every battery is treated individually, which maximises its performance and service life and reduces operating costs.
Versatility without compromise: 12V/24V, 110V supply and many battery types
The TELWIN T-CHARGE 20 110V is designed for maximum versatility to meet the varied needs of professional workshops and demanding users. A key advantage is automatic battery voltage detection, which allows trouble-free charging of both 12V systems (cars, motorcycles, boats) and 24V systems (trucks, buses, construction and agricultural machinery). This function eliminates the risk of error and simplifies operation, saving valuable time.
In addition, the 100-120V AC supply opens up new applications in regions or specific industrial environments where the 230V standard is not available. Whatever the voltage, the T-CHARGE 20 is compatible with many battery types: WET, GEL, AGM, MF, PbCa, EFB. This means one compact unit can serve practically an entire vehicle fleet or a variety of batteries in the workshop, which makes it an exceptionally economical and practical solution. Thanks to this flexibility, you always have the right tool for the job at hand.
Compact power and safety: Telwin engineering for professionals
An unusual combination of power and miniaturisation is what sets the T-CHARGE 20 apart. Its ultra-compact dimensions (17 x 6.5 x 3.5 cm) and low weight (0.6 kg) make it an ideal tool for mobile service technicians, for keeping in a toolbox or even in a vehicle storage compartment. Despite its small size, the unit delivers an effective charging current of 8A for 12V and 4A for 24V, which is enough for a broad span of battery capacities (up to 180Ah for 12V and 90Ah for 24V).
Telwin is known for its attention to safety, and the T-CHARGE 20 is no exception. It is equipped with a full set of protections, including protection against overload, short circuit and reverse polarity. These functions protect both the charger and the connected battery from damage caused by user error or unforeseen situations. In addition, the IP65 protection rating means that the housing is dust-tight and resistant to water jets, which allows safe use in tougher workshop conditions. This is reliability and peace of mind you can count on every day.
