High-Current DC Power Supply
Product Code : SCL-PL-12366
High-Current DC Power Supply (SKU SCL-PL-12366) is a regulated bench supply with a digital display, continuously adjustable from 0 to 16 V with coarse and fine controls, that works either as a constant-voltage source with current limiting or as a constant-current source with voltage limiting. Physics and electrical labs use it for electromagnet, electrolysis and circuit experiments that need heavy current. Science Lab Supplies supplies the unit from Ambala, India to schools, colleges, training institutes, tender contractors and distributors.
Specifications
The supply accepts 115/230 V, 50/60 Hz input and gives 0–16 V output with an 800 mV fine-adjustment range and a 2 A fine current-control range. Stability from 0 to 100% load is within 12 mV, residual ripple is below 1 mV, and it is protected against short circuit, overcurrent and overvoltage.

Applications and Experiments for the High-Current DC Power Supply
The supply powers experiments that need a steady, adjustable DC source at higher currents than a battery or small eliminator can provide. Constant-current mode suits electrolysis and electromagnet work, while constant-voltage mode with current limiting protects student circuits during Ohm's law and resistance practicals.
- Class 10 and Class 12 physics: magnetic field of a current-carrying coil, electromagnets and the force on a conductor.
- Class 12 physics (current electricity): Ohm's law and resistance measurements with current limiting.
- Chemistry and physics labs: electrolysis and electroplating at a controlled current.
This is a mains-powered unit that can deliver heavy current. Connect loads with leads rated for the current, switch off before changing connections, and use it under teacher or instructor supervision.
Standard Scope of Supply
The High-Current DC Power Supply is supplied as a single unit as described above, with its digital display and coarse and fine controls. Connecting leads, meters and loads are separate items and can be listed on the same quotation for the experiments you plan to run.
Packing, MOQ and Lead Time
A quotation can be made out for one power supply or for a unit on every bench in a physics or electrical lab. It states packing, delivery time and price for that quantity, and safety leads, ammeters or voltmeters can be quoted with it from Science Lab Supplies, a physics instruments supplier in India.
Science Lab Supplies, registered as an exporter with an Importer-Exporter Code, is able to ship to buyers in Ghana, Ethiopia, Tanzania, Uganda, the UAE and Saudi Arabia. Send your list via the contact page or the enquiry cart, and turn to the lab tender page for tender enquiries.
Frequently Asked Questions
What output does the High-Current DC Power Supply give?
It gives 0–16 V DC, adjustable continuously with coarse and fine controls. Current is adjustable too, with a 2 A fine current-control range, and both values appear on the digital display.
What is the difference between constant-voltage and constant-current mode?
In constant-voltage mode the output voltage stays fixed and current is limited to a set value; in constant-current mode the current stays fixed and voltage is limited, which suits electrolysis and electromagnets.
Who supplies the High-Current DC Power Supply?
Science Lab Supplies supplies this unit from Ambala, India. Institutions and distributors can order it directly and combine it with meters, leads and other electrical items on one quotation.
Which mains voltages does it accept?
It accepts 115/230 V at 50/60 Hz. Mention your local mains voltage and frequency when enquiring so they can be checked against the quotation before the order is confirmed.
