Operational Amplifier Trainer IC Regulated D.C. Power Supply

Product Code : SCL-EAE-12040

The Operational Amplifier Trainer IC Regulated D.C. Power Supply is a self-contained electronics engineering workbench used for teaching linear integrated circuit properties in technical educational environments. Engineered for electronics engineering students and science instructors, this trainer provides a stable, dual-rail regulated power base to analyze operational amplifier applications safely.

Product Description

The Operational Amplifier Trainer IC Regulated D.C. Power Supply by Science Lab Supplies features a robust glass-epoxy printed circuit board housed inside a highly durable, powder-coated steel console chassis. This specialized equipment integrates a multi-rail IC regulated DC power module directly alongside embedded operational amplifiers (such as the industry-standard 741 IC), removing the operational requirement for messy external desktop power packs.

The front panel includes high-contrast, permanent schematic diagrams displaying standard op-amp loops to support rapid student learning. By providing 2mm or 4mm insulated banana safety sockets, it allows users to patch and measure complex networks without damaging underlying traces. This setup makes it an essential long-term addition for institutions updating their pool of high-accuracy scientific laboratory instruments.

Key Features

• Dual IC Regulated D.C. Outputs: Delivers exceptionally stable, ripple-free ±15V DC lines specifically tuned for linear integrated circuits.
• Onboard Active op-amps: Outfitted with pre-mounted, socketed general-purpose 741 operational amplifiers for immediate out-of-the-box use.
• Ventilated Metal Chassis: Built within a tough, powder-coated mild steel casing designed to survive rigid classroom lab environments.
• High-Contrast Component Schematics: Explicitly displays standard electronic symbols directly on the front panel interface to facilitate student troubleshooting.
• Built-in Safety Overloads: Equipped with automatic thermal cutoff fuses that temporarily protect the unit from accidental grounding faults.
• Gold-Plated Contact Nodes: Employs low-resistance insulated safety sockets to guarantee continuous, precise measurement conductivity.

How to Use the Operational Amplifier Trainer IC Regulated D.C. Power Supply

1. Position the electronics trainer flat on a clean, dry, non-conductive laboratory workbench.
2. Verify that the primary AC power toggle switch on the rear panel is shifted to the OFF position before connecting any patch cords.
3. Construct a classic inverting amplifier circuit layout by inserting the provided banana patch cords between the onboard resistors and the 741 IC nodes to satisfy the mathematical voltage gain formula:

$$A_v = -\frac{R_f}{R_{in}}$$

1. Hook up an external function generator to the input node and connect a dual-channel oscilloscope across the output test points.
2. Plug the AC cord into a grounded electrical outlet, flip the main power switch ON, and adjust your input signal frequency to track real-time waveform amplification.

Handling Note: Always switch off the trainer console power switch before modifying or changing patch cord connections to protect sensitive semiconductor gates from unexpected high-voltage surges.

Care & Maintenance

• Terminal Care: Use only the provided compatible patch cords. Avoid forcing oversized probes or bare wires into the connection nodes to preserve internal spring tension.
• Enclosure Upkeep: Wipe down the metal casing and terminal panel interface periodically with a dry, lint-free microfiber cloth. Do not use liquid cleaning sprays or industrial alcohols.
• Storage Environment: Store the workstation inside a climate-controlled equipment locker away from high humidity, damp locations, and direct sunlight.

Frequently Asked Questions

• Does this operational amplifier trainer require an external DC bench power supply?

No, this model features a built-in monolithic IC regulated $\pm$15V DC power supply module that runs directly from standard 220V–240V AC mains.

• Can students interface external resistors and capacitors with this trainer board?

Yes, while the unit carries fixed onboard passive parts, external electrical components can be easily patch-wired into the loops via the open safety sockets.

• Are the integrated operational amplifiers soldered permanently to the board?

No, the 741 ICs are seated securely within durable 8-pin dual-in-line (DIP) sockets, allowing for simple replacement in the event of an unexpected component overload.

• What type of op-amp circuits can be configured on this workstation?

Students can readily set up inverting amplifiers, non-inverting amplifiers, voltage followers, summing networks, differentiators, and wave integrators.

• Is the integrated power supply protected against direct grounding faults?

Yes, the onboard dual power rails feature active thermal cutoffs and current limiters that safely power down the supply lines until the wiring fault is resolved.
