The Stremtec TSH-248 is an extremely advanced and cost-effective diagnostic tool specifically designed for the professional testing of modern vehicle starting, charging, and cooling systems. This generator (dynamo) tester can examine components using the latest communication protocols with outstanding accuracy, ensuring quick and reliable fault diagnosis for service centers.
The TSH-248 tester merges cutting-edge technology with user-friendly operation, enabling comprehensive testing of 12V, 24V, and the increasingly popular 48V systems.
The TSH-248 tester is the ideal choice for any workshop looking to keep pace with the evolution of the automotive industry, especially in the area of new-generation hybrid and electric vehicles (EV/PHEV), where 48V systems play an increasingly significant role.
Wide Voltage Compatibility: Capable of testing standard 12V and 24V alternators, as well as modern 48V units.
Cost-Effective Solution: One of the most favorably priced yet highly functional testing devices available on the market.
Advanced Communication Protocol Support: Exclusively manages the most modern control buses, including LIN, BSS, and CAN-BUS systems.
Protocol Version Support: Full support for BSS1, BSS2, LIN-1, LIN-2, CAN-BUS 2.0, and the newest CAN-BUS FD (Flexible Data-Rate) standards.
Dual-Channel LIN Comparison Test: Enables precise diagnostics of complex systems utilizing two LIN buses.
OBD2 Connection Capability: Prepared for the integration of diagnostic functions via the OBD2 connector (under software development).
Brand Compatibility: Supports 48V systems for Audi by default. Optionally expandable with tests for Ford, BMW, Kia/Hyundai, Volvo, and JLR (Jaguar Land Rover) brands.

The flexibility of the TSH-248 tester is further increased by optional accessories that can be adapted to the specific needs of the workshops:
Automatic Updates: The software and vehicle database always remain up-to-date.
Cloud-based Data Storage: Secure storage and retrieval of test results in the cloud.
In today's vehicles, generators are no longer just simple voltage suppliers. Start/Stop systems, increased onboard power demands, and the introduction of 48V mild-hybrid systems require complex control logic. These modern generators often communicate via LIN or CAN bus with the vehicle's central unit, and only charge when authorized by the vehicle computer (intelligent charge control).
The TSH-248 was specifically developed for this challenge:
Intelligent Charge Control Testing: By testing BSS (Battery State Sensor) and LIN protocols, the instrument can simulate vehicle control commands, verifying whether the generator reacts correctly to charging demands and communication signals.
48V System Validation: Testing 48V systems is critically important with the spread of hybrid technologies. The TSH-248 ensures that these new, higher-voltage units also operate correctly, which is essential for vehicle reliability.
CAN-BUS FD Capability: CAN-FD (Flexible Data-Rate) is becoming increasingly common in the newest models due to its higher data transfer rate. The tester's capability guarantees the ability to react immediately to future diagnostic needs.
The TSH-248 is not just a simple load test, but an in-depth, protocol-controlled diagnostic tool that provides workshops with fast and accurate fault diagnosis even for the most complex charging systems.
