AC-AC Conversion – Triac And Phase Control

Model No. DL PEL202

The DL PEL202 is a multipurpose bench to study the conversion from alternating current to alternating current. Its main fields of applications are in the control of temperature, lighting, and induction motors (with phase-control, on-off control and proportional time control). The course is divided into two sections: the first part studies thyristors and controlled AC/AC converters using power components as diodes, SCR and Triacs with two and six pulse control units and the second part shows a standard application with the study of a double-time constant light dimmer circuit consisting of Triac and Diac with fault simulation. Its modular structure makes it easy to reconfigure the system to perform several experiments in various subjects such as Triac, single-phase and three-phase controllers, to name a few.

EXPERIMENTS:
THYRISTORS AND AC VOLTAGE CONTROLLER
– TRIAC
– Fully controlled single-phase AC voltage controllers
– Fully controlled single-phase AC voltage controllers with TRIAC
– Hal controlled single-phase AC voltage controllers
– Fully controlled 3-ph AC voltage controller
– Half controlled 3-ph AC voltage controller
– Two-phase controlled 3-ph AC voltage controller
LIGHT DIMMER FAULT SIMULATOR
– Phase control for the regulation of lighting with fault simulation.
– Double time-constant standard light dimmer circuit consisting of triac, diac, two control potentiometers, resistors and capacitors.
– 20 faults can be switched on using switches located behind a cover.
– Typical faults: interruptions, short-circuit, faulty components and faulty design.
