Discover the Advanced Capabilities of the TELWIN COMPUTER 48/2 PROF 230V 6-48V
PULSE TRONIC Technology: The Smart Heart of Your Battery
The TELWIN COMPUTER 48/2 PROF uses revolutionary PULSE TRONIC technology, the essence of smart battery charging and maintenance management. This is not ordinary charging; it is an advanced 8-stage algorithm that precisely analyses, diagnoses and responds to the individual needs of every connected battery, regardless of its type (WET, GEL, AGM, MF, PbCa, EFB, Li) or depth of discharge.
The system starts by checking the battery condition and then, if necessary, initiates the desulfation process (RECOVERY), using special current pulses to break up lead sulfate crystals and restore lost capacity. The following stages include bulk charging with optimised current, an absorption phase to reach 100% charge and finally smart float (maintenance) charging that keeps the battery in ideal condition for a long time without the risk of overcharging. With PULSE TRONIC, the life of your batteries can be significantly extended, which means real savings and dependable equipment.
Versatility Without Compromise: One Unit, Endless Possibilities
One of the greatest strengths of the TELWIN COMPUTER 48/2 PROF is its unrivalled versatility. Charging voltages from 6V, through the common 12V and 24V, up to the specialised 36V and 48V let you work with practically any type of vehicle and machine. From motorcycles and quads, through cars, SUVs and vans, to heavy construction and agricultural machinery, buses, forklifts or emergency power systems, this model can handle the job.
In addition, compatibility with many battery types, including conventional lead-acid (WET), gel (GEL), AGM, MF, PbCa, EFB and modern lithium (Li) batteries, makes it a truly universal tool. Automatic battery type recognition and adjustment of the charging characteristic remove the risk of error and ensure optimal treatment of every battery. For a professional workshop this means fewer units needed, simpler processes and the certainty of always having the right tool for the job.
Full Control: Diagnostics and SUPPLY Function for Advanced Service Work
The TELWIN COMPUTER 48/2 PROF is much more than a charger. It is an advanced diagnostic centre for the vehicle power system. Integrated test functions give a fast and precise assessment of the battery condition (including a cranking capacity test), the alternator and the performance of the starting system. Test results are clearly displayed, which makes it easier to identify problems and take the right service action.
The SUPPLY function is also extremely useful in modern workshops. It lets you use the unit as a stable power source at a set voltage (for example during battery replacement, ECU flashing or computer diagnostics). This prevents the loss of settings in on-board systems and the need to recode components, and protects sensitive electronics against voltage spikes. For a professional this means safety, time savings and the ability to offer complete services at the highest level.
Reliability and Power for Demanding Users: Telwin Pro Performance
For years the Telwin brand has stood for reliability and innovation in the welding and workshop sector. The COMPUTER 48/2 PROF continues this tradition, offering professionals a tool built for intensive daily work. A solid metal housing and practical transport wheels provide durability and mobility, even in harsh workshop conditions.
The unit offers an impressive 1500W of power and high charging currents (up to 75A for 6/12V), so it charges high-capacity batteries of up to 1000Ah quickly and effectively. This is essential for service shops handling heavy equipment or vehicle fleets, where downtime must be kept to a minimum. Advanced protection systems against short circuit, reverse polarity, overload and overheating keep the operator, the battery being charged and the vehicle electronics safe. By choosing the Telwin COMPUTER 48/2 PROF, you invest in peace of mind, productivity and professionalism for years to come.
