The TELWIN COMPUTER 48/2 PROF uses the revolutionary PULSE TRONIC technology, which is the quintessential intelligent management of the battery charging and maintenance process. It’s not just charging; it’s an advanced 8-step algorithm that precisely analyzes, diagnoses and responds to the individual needs of each connected battery, regardless of its type (WET, GEL, AGM, MF, PbCa, EFB, Li) or degree of discharge.

The system begins by verifying the condition of the battery, then, if necessary, initiates the desulfation (RECOVERY) process with special current pulses, breaking down lead sulfate crystals and restoring lost capacity. Subsequent stages include a base charge with current optimization, an absorption phase to achieve 100% charge, all the way to an intelligent maintenance (maintenance) charge that keeps the battery in perfect condition for a long time without the risk of overcharging. With PULSE TRONIC, the life of your batteries can be significantly extended, resulting in real savings and equipment reliability.

One of the greatest strengths of the TELWIN COMPUTER 48/2 PROF is its unparalleled versatility. Supporting charging voltages from 6V, through the popular 12V and 24V, to specialized 36V and 48V, it opens the door to working with virtually any type of vehicle and machine. From motorcycles and ATVs, to cars, SUVs, delivery vehicles, to heavy construction equipment, agricultural machinery, buses, forklifts or emergency power systems, this model is up to any challenge.

Moreover, compatibility with a wide range of battery types, including traditional lead-acid (WET), gel (GEL), AGM, MF, PbCa, EFB, as well as modern lithium (Li) batteries, makes it a truly universal tool. Automatic recognition of battery type and adjustment of charging characteristics eliminates the risk of confusion and ensures optimal treatment of each battery. For the professional workshop, this means reducing the number of devices needed, simplifying processes and ensuring that it always has the right tool for the job.

TELWIN COMPUTER 48/2 PROF is much more than just a charger. It is an advanced diagnostic center for a vehicle’s power system. Integrated test functions allow quick and precise evaluation of battery condition (including a test of starting capacity), alternator efficiency and starting system performance. Test results are clearly displayed, making it easy to identify problems and take appropriate service actions.

Extremely useful in modern workshops is also the SUPPLY function. It allows the device to be used as a stable power source with a specific voltage (for example, when replacing the battery, flashing the ECU, or performing computer diagnostics). This prevents the loss of settings in on-board systems, the need to re-code components, and protects sensitive electronics from voltage spikes. For the professional, this means safety, time savings and the ability to provide comprehensive services at the highest level.

For years, the Telwin brand has been synonymous with reliability and innovation in the welding and workshop industry. The COMPUTER 48/2 PROF model continues this tradition, offering professionals a tool designed for intensive daily work. The robust metal housing and practical transport wheels ensure durability and mobility, even in harsh workshop conditions.

The unit has an impressive 1500W of power and high charging currents (up to 75A for 6/12V), allowing it to quickly and efficiently charge high-capacity batteries up to 1000Ah. This is crucial for service facilities operating heavy equipment or vehicle fleets, where downtime must be kept to a minimum. Advanced protection systems against short-circuiting, pole swapping, overloading or overheating guarantee safety for both the operator, the battery being charged and the vehicle electronics. When you choose the Telwin COMPUTER 48/2 PROF, you are investing in peace of mind, performance and professionalism for years to come.
