Operational Amplifier Trainer 3 DC Regulated

Product Code : SCL-EAE-12059

The Operational Amplifier Trainer is an educational electronics apparatus used for practical study of op-amp circuits, including inverting, non-inverting, summing, difference, integrator, differentiator, buffer, and waveform-conversion configurations. It is intended for students, instructors, engineering colleges, technical institutes, vocational centres, and electronics laboratories requiring structured analog circuit experimentation.

Product Description

The Operational Amplifier Trainer 3 DC Regulated combines three regulated DC power supplies, two dual-range moving-coil meters, selectable resistors and capacitors, and a printed circuit diagram on one laboratory platform. The verified configuration provides two 0–1.5 V DC/150 mA regulated supplies and one ±15 V DC regulated supply.

Students can use the apparatus to construct and observe multiple operational-amplifier configurations while comparing measured results with theoretical calculations. It complements other Electronics Lab Equipment and Electrical and Electronics apparatus used for analog electronics and circuit-training applications.
