Operational Amplifier Trainer Power Supply

Product Code : SCL-EAE-12055

The Operational Amplifier Trainer Power Supply is an educational electronics trainer used for studying operational amplifier circuits, IC 741 applications, analog signal processing, and amplifier configurations through practical experiments. It is designed for students, teachers, engineering colleges, technical institutes, vocational centres, and electronics laboratories requiring hands-on study of op-amp principles.

Product Description

The Operational Amplifier Trainer combines regulated power supplies, an on-board function generator, IC 741 operational amplifiers, circuit components, ZIF sockets, and connection terminals in one laboratory platform. The verified configuration provides fixed ±5 V DC and ±12 V DC at 250 mA, together with a variable 1.2–10 V DC at 250 mA supply.

The trainer supports practical investigation of inverting and non-inverting amplifiers, comparators, adders, subtractors, integrators, differentiators, waveform generators, and converter circuits. It complements other Electronics Lab Equipment and Electrical and Electronics apparatus used for analog electronics education.

Key Features

• Multiple regulated DC supplies: Provides fixed ±5 V DC, fixed ±12 V DC at 250 mA, and variable 1.2–10 V DC at 250 mA.
• 100 kHz function generator: Generates sine, square, and triangular waveforms for circuit experiments.
• Two IC 741 operational amplifiers: All pins are terminated through 2 mm banana sockets for convenient experimental connections.
• Two ZIF sockets: Includes 14-pin and 16-pin sockets for practical circuit development.
• Built-in component banks: Provides resistors, capacitors, diodes, Zener diode, and potentiometers for multiple experiments.
• Practical connection system: Uses 2 mm brass sockets and compatible patch cords.
• More than 12 experiment possibilities: Supports a broad range of fundamental operational-amplifier applications.
• Laboratory-oriented enclosure: The verified reference configuration uses an ABS plastic cabinet.

How to Use the Operational Amplifier Trainer Power Supply

1. Place the trainer on a clean, dry, and stable laboratory bench.
2. Select the required operational-amplifier experiment and review its circuit diagram.
3. Keep the trainer switched off while making connections.
4. Use the 2 mm patch cords to construct the required circuit.
5. Select the appropriate fixed or variable DC supply for the experiment.
6. Apply a waveform from the on-board function generator when required.
7. Switch on the trainer and measure the relevant input and output parameters.
8. Compare practical readings or waveforms with theoretical calculations.
9. Switch off the equipment before changing connections or removing components.

Safety note: Always verify IC orientation, supply polarity, voltage level, and circuit connections before energising the trainer.

Care & Maintenance

• Keep sockets, patch cords, and the front panel clean and dry.
• Never insert or remove ICs while power is applied.
• Avoid exceeding the specified supply ratings or applying incorrect polarity.
• Store the trainer in a dry, dust-free environment after use.
