Explore the Advanced Capabilities of TELWIN MASTERCHARGE FLEX 22 230V /400V
?? Intelligent Diagnostics and Regeneration with Pulse Tronic
Pulse Tronic technology is the real operating brain of the Telwin MASTERCHARGE FLEX 22 charger. It’s not just automatic charging, but an entire, advanced process for managing the condition of the battery, divided into 8 intelligent stages. Each cycle begins with a thorough analysis (CHECK) of the battery’s condition, checking its voltage, charge level and possible sulfation.
Based on this diagnosis, the system selects the optimal strategy. For deeply discharged or sulfated batteries, the regeneration phase (RECOVERY / DESULFATION) is triggered, using special current pulses to dissolve lead sulfate crystals, restoring lost capacity. The rectifier then proceeds to the main charge (BULK), delivering maximum current until about 80% of capacity is reached. An absorption phase (ABSORPTION) completes the charge to 100% at a constant voltage, and a final analysis (ANALYSE) verifies that the battery is holding its charge correctly. The whole thing is topped off with a pulse maintenance mode (PULSE / FLOAT), which keeps the battery in optimal condition for an unlimited time, compensating for self-discharge without the risk of overcharging. For the professional, this means full automation, maximum battery life and confidence in battery readiness.
?⚡ Unmatched Power Flexibility: 230V/400V FLEX Technology
One of the greatest strengths of the Telwin MASTERCHARGE FLEX 22 is its ability to work with a variety of electrical power systems. Whether you have a standard 230V single-phase outlet in your workshop or have access to a 230V or 400V three-phase system, this charger will automatically adapt to the available source, ensuring full power and charging performance at all times.
This flexibility is a huge advantage, eliminating the need for different equipment or transformers. This is especially valuable in large workshops, truck and machinery services, where the power infrastructure can be diverse, and for mobile services that need to be ready for any conditions. An active PFC (Power Factor Correction) circuit further optimizes power consumption, reduces interference introduced into the grid and increases the overall energy efficiency of the device, resulting in lower operating costs and greener operation.
?️? SUPPLY Mode and Advanced Testing: Your Service Assistant
The MASTERCHARGE FLEX 22 is much more than just a charger. The SUPPLY function allows the unit to be used as a stabilized 12V or 24V DC power source. This is invaluable for service work, such as replacing the battery without losing the settings of the on-board computer, radio or comfort systems. It also makes it possible to safely perform vehicle diagnostics with the tester connected, or to update the control unit (ECU) software, where a stable voltage is absolutely crucial to the success of the operation and avoid costly damage.
In addition, the charger offers advanced test functions. You can quickly verify the state of charge of the battery, check the correct operation of the vehicle’s alternator (charge voltage test) and assess the battery’s starting capacity. These integrated tests allow you to quickly diagnose problems with your vehicle’s electrical system, saving you time and allowing you to pinpoint the source of the fault. For a professional service provider, this is a comprehensive diagnostic and support tool.
?️? Safety and Ecology: Telwin’s Priorities
In designing the MASTERCHARGE FLEX 22, Telwin placed great emphasis on the safety of the user, the device and the battery being charged. The charger is equipped with a number of safety features, including protection against reverse polarity (with signaling), terminal short-circuit, overload and overheating. Special algorithms prevent sparking when connecting and disconnecting clamps, which is especially important when working with batteries that emit gases.
Telwin also cares about the environment. The use of Power Stream technology and active PFC significantly increases the energy efficiency of the device, resulting in lower power consumption and a reduced carbon footprint. Intelligent charging programs, including regeneration, contribute to extending the life of the batteries, which reduces hazardous waste. When you choose the Telwin MASTERCHARGE FLEX 22, you not only get a reliable and efficient tool, but also contribute to more sustainable operation.
