Product Code : SCL-EI-10551

The AC/DC Power Supply 2-14 V 3 A is a student laboratory power supply used for providing low-voltage AC and DC output during physics, electronics, and basic electrical circuit experiments. It is suitable for schools, colleges, STEM laboratories, electronics trainers, physics practical rooms, and student workbenches where controlled electrical power is required.

Product Description

The AC/DC Power Supply 2-14 V 3 A from Lab Glassware Manufacturer is designed for practical circuit exercises involving lamps, motors, resistors, switches, electromagnets, coils, buzzers, meters, and basic electronic components. The stated 2–14 V output range supports low-voltage classroom work, while the 3 A current rating makes the unit suitable for many school-level electrical loads when used within confirmed safety limits.

How to Use the AC/DC Power Supply 2-14 V 3 A

1. Place the power supply on a dry, stable, insulated laboratory bench.
2. Confirm that the selected AC or DC output matches the student experiment.
3. Check the mains lead, plug, fuse holder, output terminals, display, and control knobs before use.
4. Set the output to the lowest voltage before connecting the circuit.
5. Connect the circuit using suitable insulated leads and correct polarity for DC circuits.
6. Select the required output between 2 V and 14 V according to the experiment.
7. Switch on the output and observe lamp brightness, motor speed, coil effect, or meter readings.
8. Switch off and disconnect the circuit before changing components, terminals, or AC/DC mode.

Safety note: Use only under teacher or technician supervision. Do not short the output terminals, exceed the 3 A rating, open the casing, use damaged leads, or connect circuits beyond the confirmed voltage and current limits.

Care & Maintenance

• Keep the power supply dry, ventilated, and away from dust, moisture, chemicals, and metal filings.
• Inspect mains cable, plug, output sockets, fuse holder, and leads before every practical session.
• Store output leads separately to prevent insulation damage and loose terminal contact.
• Replace fuses only with the confirmed fuse rating and type specified by the manufacturer.
• Have damaged units inspected by a qualified technician before reuse.

Frequently Asked Questions

What is the AC/DC Power Supply 2-14 V 3 A used for?

It is used to provide low-voltage AC and DC power for student experiments involving circuits, lamps, motors, coils, resistors, electromagnets, and basic electronics.

What is the output range of this power supply?

The stated output range is 2-14 V with a 3 A current rating. Confirm whether the voltage is stepped, continuously variable, separately available for AC and DC, or selectable by switch.

Does it provide both AC and DC output?

The product name specifies AC/DC, but the exact output configuration must be confirmed. Verify whether the unit has separate AC and DC terminals, selectable output, or simultaneous outputs.

Can students use it for Ohm’s law experiments?

Yes, if the connected resistors, meters, and circuit components are rated for the selected voltage and current. Use suitable low-voltage settings and teacher supervision.

Is this power supply protected against overload?

Overload protection is not confirmed. Add fuse, current limiting, short-circuit protection, or thermal protection details only after checking the final datasheet.

What should be confirmed before ordering?

Confirm AC/DC output configuration, stepped or variable control, number of channels, terminal type, fuse rating, overload protection, short-circuit protection, display type, input voltage, plug type, safety certification, included leads, packing, and instruction guide availability.
