The Rotrix TSH-012 is a professional diagnostic tool specifically designed for the comprehensive testing of the technical condition of 12V and 24V voltage regulators. This device is crucial for repair shops as it enables full-range testing of regulators against preset rotor resistance values, as well as diagnostics of modern units equipped with communication protocols (COM).
The Rotrix TSH-012 is the ideal choice for any specialist working in the field of starters, generators, and cooling systems who requires reliable, fast, and precise measurements.
The tester evaluates the technical condition of the voltage regulators based on the following criteria:
Continuity of the indicator lamp circuit: Checks the operation of the charge indicator lamp (D+).
Output voltage setting channel performance: Tests the voltage regulation capability.
Feedback channel performance: Ensures the correct feedback function of the regulator.
Stabilization voltage: Measures the actual stabilization voltage and its compliance with the set value.
Generator speed activation speed: Determines the engine speed (RPM) at which the voltage regulator activates the charge.
Load maintained by the voltage regulator: Capable of simulating load to test the full capacity of the regulator.
For voltage regulators equipped with modern digital communication (e.g., LIN, BSS), the TSH-012 also evaluates the following parameters:
Voltage regulator identifier (ID).
The operational capability of the voltage regulator's diagnostic system.
Type of data exchange protocol.
Data exchange speed.
Potential error codes (Errors).
In addition, the tester assists in selecting the appropriate analog voltage regulator for any given generator.
During the design of the Rotrix TSH-012, special attention was paid to user-friendly operation and safety:
Integrated Health Check: The device provides a comprehensive, built-in assessment of the voltage regulator's status.
Intuitive Operation: The user-friendly interface and touchscreen ensure simple and fast handling of the tester.
Color-Coded Cabling: Color-coding the wires minimizes the risk of connection errors, ensuring the correct wiring of the regulator.
Free Firmware Updates: The device software updates are available free of charge, ensuring the tester always stays up-to-date with new regulator types.
Built-in Protection Systems: The tester features built-in protection mechanisms that prevent device damage in case of incorrect connection of the voltage regulator.
