Telwin MASTERCHARGE FLEX 22: Professional, Intelligent 230/400V Charging for Your Fleet and Workshop.
Imagine full control over charging every battery in your workshop or vehicle fleet, whatever its type and however unreliable the power source. With the Telwin MASTERCHARGE FLEX 22 230V/400V this becomes reality. It is not an ordinary charger but an advanced energy management centre, designed by Telwin's Italian engineers to meet the highest demands of professionals and enthusiasts who accept no compromise on reliability and performance.
Forget downtime caused by an unexpectedly flat battery or worries about damaging a vehicle's sensitive electronics. Thanks to Power Stream technology and the intelligent Pulse Tronic charging programs, the MASTERCHARGE FLEX 22 delivers not just current but a precisely matched treatment for every battery, from standard WET through GEL, AGM, MF, PbCa and EFB to modern lithium batteries (Li). Its ability to run on both single-phase 230V and three-phase 230V/400V supplies gives you exceptional flexibility and lets you work efficiently in typical workshop or field conditions.
Investing in the MASTERCHARGE FLEX 22 means investing in peace of mind and continuity of work. This charger does more than charge: it also diagnoses batteries, regenerates sulphated cells and can serve as a stable power source (SUPPLY function) during service work or computer diagnostics, protecting the vehicle's sensitive systems. It is a versatile tool that raises the standard of your work, optimises battery running costs and makes sure your vehicles and machines are always ready for use. Discover the precision and reliability that come with the Telwin name.
Explore the Advanced Features of the TELWIN MASTERCHARGE FLEX 22 230V /400V
Intelligent Diagnostics and Regeneration with Pulse Tronic
Pulse Tronic technology is the real brain of the Telwin MASTERCHARGE FLEX 22 charger. It is not just automatic charging but a complete, advanced process for managing battery condition, divided into 8 intelligent stages. Each cycle starts with a thorough analysis (CHECK) of the battery, which checks its voltage, state of charge and any sulphation.
Based on this diagnosis, the system selects the optimum strategy. For deeply discharged or sulphated batteries it starts the regeneration phase (RECOVERY / DESULFATION), which uses special current pulses to dissolve lead sulphate crystals and restore lost capacity. The charger then moves on to main charging (BULK), delivering maximum current until about 80% of capacity is reached. The absorption phase (ABSORPTION) completes charging to 100% at constant voltage, and the final analysis (ANALYSE) checks whether the battery holds its charge properly. The cycle ends with pulse maintenance mode (PULSE / FLOAT), which keeps the battery in optimum condition for an unlimited time and compensates for self-discharge without any risk of overcharging. For a professional this means full automation, maximum battery life and confidence that the batteries are ready for work.
Exceptional Supply Flexibility: FLEX 230V/400V Technology
One of the biggest strengths of the Telwin MASTERCHARGE FLEX 22 is its ability to work with different electrical supply systems. Whether your workshop has a standard single-phase 230V socket or access to a three-phase 230V or 400V installation, the charger automatically adapts to the available source and always delivers full power and charging performance.
This flexibility is a major advantage, because you no longer need different units or transformers. It is particularly valuable in large workshops and in truck and machinery service, where the power infrastructure can vary, and for mobile service teams that must be ready for any conditions. The active PFC circuit (Power Factor Correction) also optimises power consumption, reduces interference fed back into the mains and increases the overall energy efficiency of the unit, which means lower running costs and more environmentally friendly operation.
SUPPLY Mode and Advanced Tests: Your Service Assistant
The MASTERCHARGE FLEX 22 is much more than a charger. The SUPPLY (power supply) function lets you use the unit as a stabilised 12V or 24V DC source. This is invaluable during service work such as replacing the battery without losing the settings of the on-board computer, radio or comfort systems. It also allows safe vehicle diagnostics with a scan tool connected or software updates for control units (ECU), where a stable voltage is essential for the operation to succeed and to avoid costly damage.
In addition, the charger offers advanced test functions. You can quickly check the battery state of charge, verify correct alternator operation in the vehicle (charging voltage test) and assess the cranking ability of the battery. These integrated tests allow quick diagnosis of problems in the vehicle's electrical system, save time and help you pinpoint the source of a fault. For a professional service it is a complete diagnostic and support tool.
Safety and Environment: Telwin's Priorities
When designing the MASTERCHARGE FLEX 22, Telwin put great emphasis on the safety of the user, the unit and the battery being charged. The charger has a number of protections, including protection against reverse polarity (with indication), short-circuiting of the clamps, overload and overheating. Special algorithms prevent sparking when the clamps are connected and disconnected, which is particularly important when working with batteries that give off gas.
Telwin also cares about the environment. Using Power Stream technology and active PFC significantly increases the energy efficiency of the unit, which means lower electricity consumption and a smaller carbon footprint. Intelligent charging programs, including regeneration, help to extend battery life, which reduces the amount of hazardous waste. By choosing the Telwin MASTERCHARGE FLEX 22 you get a reliable, efficient tool and also contribute to more sustainable operation.

Key Features and Benefits
- Power Stream & Pulse Tronic technology: The heart of the MASTERCHARGE FLEX 22 charger, providing up to 50% higher efficiency than traditional chargers. Power Stream gives full control over the charging process, while the advanced Pulse Tronic system, based on 8 intelligent phases, automatically diagnoses the battery condition, optimises charging parameters, performs desulphation (RECOVERY) and keeps the battery in ideal condition (PULSE) for a long time. For the professional this means faster recovery of batteries, a much longer service life, lower replacement costs and the certainty that every battery (WET, GEL, AGM, Li) is treated individually and optimally.
- FLEX supply flexibility (230V/400V) and active PFC: The ability to work across a broad span of input voltages, single-phase 230V as well as three-phase 230V or 400V, is a real step forward in mobility and adaptability. Whatever power infrastructure is available in the workshop or in the field, the MASTERCHARGE FLEX 22 delivers full power. The integrated active power factor corrector (PFC) minimises energy losses, reduces harmonic interference in the mains and ensures high efficiency. The benefit: you can use the charger in almost any conditions, with lower energy bills and stable, reliable operation even on an unstable supply.
- Versatile support for all battery types: Whether you work with classic lead-acid (WET), maintenance-free (MF), gel (GEL), AGM, EFB, calcium (PbCa) or the latest lithium batteries (LiFePO4/LFP), the MASTERCHARGE FLEX 22 is ready for the job. Dedicated charging algorithms for each battery chemistry ensure safety and maximum efficiency. For the professional this means one universal unit for the whole range of batteries, with no need for several specialist chargers and no risk of damaging a battery with the wrong charging mode.
- SUPPLY function (stabilised power supply): A very useful function that turns the charger into a stable DC power source. During battery replacement, computer diagnostics of the vehicle (e.g. ECU flashing) or service work that requires the voltage to be maintained, SUPPLY mode provides a constant, safe voltage and protects the sensitive on-board electronics from data loss or damage. For the mechanic it is invaluable help that keeps service procedures safe and eliminates the risk of costly failures of the vehicle's electronic systems.
- Advanced protection and robust construction: Telwin focuses on safety and durability. The MASTERCHARGE FLEX 22 has a complete protection system that safeguards the user, the charger and the battery being charged. It covers overload, short circuit, reverse polarity, sparking and overheating. The robust housing, built to withstand workshop conditions, ensures long, trouble-free operation. You get safe operation in typical workshop conditions and a tool that can handle intensive use, minimising the risk of breakdowns and downtime.
