AST1115 training bench of a dimmer single phase 3 phases with load Didactic Equipment
1.Product introduction
1.1 overview
By single-phase dimmer and three-phase uplink dimmers related experiment, the experiment of single-phase dimmers can be familiar with and the characteristics of three-phase uplink dimmers, grasp its control principle and control mode, the corresponding knowledge and skills, suits, higher vocational colleges, secondary vocational schools and vocational school related professional teaching and skills training examination.
1.2 features
(1) the training platform adopts the frame structure of aluminum profile, which can be moved flexibly. The measuring instrument and the actual training power supply built-in integration installation, easy to use, not easy to damage.
(2) the actual training platform is fully configured, and the modules can be used in combination to complete a variety of training contents.
(3) the training platform has a good security system.

3. Complete experiment
(1) single-phase dimmer experiment
(2) three-phase uplink dimmer experiment
(3)Power module allows to study:
Single phase dimmer (with phase angle)
Upstream dimmer 3phases (with phase angle neutral and phase angle without neutral)
Powered by 230V/400V, 50Hz
Power: 1 kW at least
Principle schema of the dimmer is figure on the module face
(4)Command unit:
Initiating angle adjusting is accessible by direct digital display by degree
The unit allows data acquisition of different command signal signal of the three branches, output currents and voltages values Synoptic schema on the module face
The module is protected against false maneuvering (short-circuit, overloads, …)
5)Power supply unit: 1kW at least adapted to the power module, protected against short circuit and over loads (if protected b fuse provide 10 spares)
(6)Loads unit:
3 phases resistive load 1kW
3 phases inductive load 1kVA
Asynchronous motor 3 phases 700W
