Modern configuration: smart fuse for completely short-circuit-proof operation, LED lights, blocking diodes, analog and digital turn signal relays, horn. Four switches, three relays, six lamps—all components are freely wireable just like with plug-in modules. For students who want to truly understand circuits in real vehicles.
What the trainer does in class — shown in a minute, with sound. Subtitles can be switched on in the player.
Terminal 30 at the top, terminal 31 at the bottom—and everything in between that makes up a vehicle electrical system. Each component can be connected individually via 2-mm safety sockets and freely wired, just like with plug-in modules. The result: Trainees build real circuits themselves instead of just reading about them in a book.
Art. No. 12020170 The changes compared with the TP-Lab Electric Trainer — point by point, straight from development.
A fresh take on the classic vehicle electrical system: more compact, more modular, and more realistic in terms of faults. From passively reading schematic diagrams to actively building circuits.
Instead of having to replace the fuse wire after every measurement fault: the smart fuse shuts off and is immediately ready for use again. Students can experiment without fear, and teachers don’t have to go through the hassle of resetting the device.
A classic hot-wire turn signal relay and a modern electronic turn signal relay on a trainer. Trainees can understand the generational shift in the vehicle electrical system directly by examining the components—and can compare the two using measurement technology.
Four switches, three relays, six lights, a horn, blocking diodes, resistors—all individually connectable via 2-mm safety sockets. Like plug-in modules, but using genuine automotive components.

The TP-Lab Electrical Trainer 4.0 is the first step on the vehicle electrical system track. Building on that, the course covers sensors, actuators, and finally the alternator system.
Trainees learn terminal designations, wiring diagrams, circuit design, and troubleshooting using actual vehicle electrical system components. With a digital curriculum and the accompanying E-Learning.
The TP-Lab Electrical Trainer 4.0 comes with a complete course on TPGO. It runs in the browser — tablet, phone, computer. The tasks walk through the same measurements the apprentice takes on the trainer: first the assumption, then the series of readings, then the comparison.
Fundamentals 60 % · Advanced 40 % SOLO 2–4 · Applying Bloom · EQF 2–3
Examples — in total the course is mapped to more than 90 curricula.
Certificate · Progress & XP
License for an unlimited number of students and teachers · Term: 10 years, renewable · Activation on your TPGO E-Learning domain.
