Power Electronics Trainer PET V2 Modular

The Power Electronics Trainer is a modular training system designed for comprehensive practical study of power semiconductor devices, their characteristics, triggering techniques, rectifier circuits, switching, and AC phase-control applications. It supports experiments on SCR, TRIAC, UJT, MOSFET, IGBT, DIAC, PUT, power transistor, and power diode characteristics. The trainer also covers digital firing, UJT triggering, resistor-capacitor triggering, rectification, TRIAC switching, and AC phase-control experiments. Its modular design allows practical study using dedicated experimental circuits and interchangeable modules. Designed and manufactured by Atico Export to meet the practical demands of modern laboratories.
