 (1).png)
Product Code : SCL-EAE-12040
Operational Amplifier Trainer IC Regulated D.C. Power Supply (SKU SCL-EAE-12040) is an analog IC workstation in which a monolithic IC-regulated ±15 V supply powers two socketed 741 op-amps, with metal-film resistors, capacitors and trimming potentiometers laid out under printed schematics. It is built for teaching linear IC properties to electronics engineering students. Science Lab Supplies produces it at its factory at Plot 448, HSIIDC Industrial Area, Saha, Ambala, India, and quotes colleges, polytechnics, tender contractors and distributors directly.
Specifications
The table below covers each specification. To summarise, a 220–240 V AC input drives IC-regulated +15 V and −15 V rails at 500 mA, two 741 op-amps sit in 8-pin DIP sockets beside metal-film resistors, non-polarised capacitors and potentiometers, and connections use 2 mm or 4 mm safety sockets in a steel and ABS case.

Applications and Experiments for the IC Regulated Op-Amp Trainer
Students build standard op-amp circuits on the panel, feed in a test signal and compare the output amplitude and shape with the gain formula. The trainer serves B.Tech, diploma and B.Sc. electronics labs studying linear integrated circuits, and fits signal-conditioning modules in NSQF electronics training.
- Amplifier configurations: inverting, non-inverting, summing and differential amplifiers and voltage followers.
- Waveform processing: active integrators and differentiators on continuous signals.
- Signal conditioning: active low-pass filters and instrumentation amplifier practice.
- Measurement set-up: a Bench Signal Generator at the input and the output displayed on an Oscilloscope.
Standard Scope of Supply
One trainer is supplied with the primary console unit, 15 colour-coded 2 mm or 4 mm banana patch cords in red, black and blue, a detachable 3-pin heavy-duty AC cord and an English operations manual with circuit wiring diagrams. Test instruments are not included.
Packing, MOQ and Lead Time
Quotations cover anything from one console to a full analog electronics lab. Science Lab Supplies sets out the packing, delivery time and price for your quantity on each quotation, and test instruments or companion trainers can be priced together with it.

Frequently Asked Questions
What power supply is built in?
A monolithic IC-regulated dual supply gives +15 V and −15 V DC at 500 mA from 220–240 V AC mains, so no external bench supply is required for the onboard op-amps.
Can the op-amps be replaced?
Yes. Both 741 op-amps are held in 8-pin dual-in-line (DIP) sockets rather than soldered to the board, so an overloaded IC can be swapped easily by a technician.
How is it different from the Operational Amplifier Trainer 3 DC Regulated?
The Operational Amplifier Trainer 3 DC Regulated has three regulated supplies, including two 0–1.5 V variable outputs, plus two dual-range moving-coil meters. This model provides IC-regulated ±15 V rails and two socketed 741 op-amps.
Is Science Lab Supplies the manufacturer or a trader?
Science Lab Supplies is the manufacturer. The trainer is produced at its own factory in Saha, Ambala, India, and the quotation comes directly from there rather than through a trading company.
