AL-E1122 AUTOMATIC POWER FACTOR CONTROLLER TRAINER

Detailed Technical Specifications

Automatic Power Factor Controller Trainer

Model AL-E11221

----------------------------------------------------------------------------------------------------------------------------------------------------------- General Description

The Automatic Power Factor Controller Trainer, Model AL-E1122, is designed for practical study of power factor measurement, automatic power factor correction, three-phase electrical supply systems, and capacitor bank switching. The trainer is built on an aluminium-profile frame with clearly labelled modules, electrical connection terminals, measuring instruments, control switches, indicator lamps, and an automatic power factor controller.

It is suitable for electrical engineering laboratories, polytechnic institutions, industrial training centres, and power systems laboratories.

2. Detailed Technical Specifications

The specifications above distinguish features visible on the supplied trainer image from ratings that require confirmation. Exact supply voltage, current, capacitor-bank ratings and meter accuracy are not readable or confirmed.

3. Main Functional Modules

3.1 Three-Phase Supply Module

• Three-phase supply section with R, Y and B phase indicators.
• Input supply switching and circuit protection.
• Emergency-stop facility.
• Colour-coded terminals for phase and neutral connections.

3.2 Digital Meter Module

• Digital AC measurement instruments.
• Dedicated input terminals for measurement connections.
• Separate meter supply connections, as indicated on the panel.

3.3 Multifunction Meter Module

• Multifunction electrical meter for monitoring supported electrical parameters.

• RS485, alarm and relay connection terminals.
• Front-panel controls and digital display.

3.5 Load Switching and Demonstration Module

• Multiple labelled load sections.
• Indicator lamps and switching terminals.
• Printed circuit diagrams for practical circuit connection.
• Terminals for studying switching and control operation.

3.6 Protection and Indication Module

• Emergency-stop push button.
• Circuit breaker arrangement.

4. Scope of Learning and Experiments

The trainer can be used to conduct practical exercises related to its installed modules, including:

1. Study of a three-phase AC supply system.
2. Measurement of AC electrical parameters using digital meters.
3. Study of power factor and its significance in AC circuits.
4. Study of the operating principle of an automatic power factor controller.
5. Demonstration of automatic and manual controller modes, where supported.
6. Study of load switching and its effect on electrical parameters.
7. Observation of power factor correction using suitable capacitive loads, if the corresponding capacitor bank is included.
8. Study of controller alarm, relay and RS485 interfaces.

These experiments should be matched to the actual supplied circuit configuration and controller manual.

5. Construction and Safety Features

• Rigid aluminium-profile supporting frame.
• Modular front panel with printed labels and schematic diagrams.
• Colour-coded electrical connection terminals.
• Main supply protection through a circuit breaker.
• Emergency-stop facility.
• Indicator lamps for operational status.
• Clearly identified measurement and controller connections.

The trainer must be operated under qualified supervision. Appropriate earthing, overcurrent protection and safe isolation should be verified before energising the equipment.
