Power Supply Unit/ Block for DC
Product Code : SCL-CL-11862
Power Supply Unit/ Block for DC (SKU SCL-CL-11862) is a bench power supply that gives regulated DC from 0 to 9 V at up to 2.5 A, plus a non-regulated AC output at 2.5 A. A rotary switch selects the voltage, a thermal circuit breaker and fuse protect against overload or short circuit, and an illuminated rocker switch shows when it is on. It powers low-voltage school and college circuits. Schools, colleges, training institutes, tender contractors and distributors can obtain the unit from Science Lab Supplies in Ambala, India.
Specifications
The DC output is regulated over 0–9 V with a current of 2.5 A. The AC output is non-regulated at a fixed voltage from 5 to 9 V, also at 2.5 A. The voltage is chosen by turning the knob clockwise until the wanted value lines up with the index mark.

Applications and Experiments for the DC Power Supply Unit
A regulated low-voltage source replaces cells and batteries in electricity practicals, giving steady, repeatable voltages that students can step through. With DC up to 9 V and an AC output, the unit suits school circuit work, college physics labs and basic electrical training.
- NCERT Class 10 science, electricity: stepping the voltage to plot current against voltage for Ohm's law.
- Resistors in series and parallel: powering circuits for Class 10 and Class 12 activities.
- CBSE Class 12 physics practicals that need a steady low-voltage DC source.
- ITI and vocational electrical training: bench supply for low-voltage circuits and component testing.
The unit runs from the mains, so connect and switch it under teacher supervision, keep it dry, and let the circuit breaker reset rather than bypassing it after an overload.
Standard Scope of Supply
The Power Supply Unit/ Block for DC is supplied as a single unit with its rotary switch, circuit breaker, fuse and rocker switch, as described above. Connecting cables, meters and circuit components are separate items and can be listed on the quotation.
Packing, MOQ and Lead Time
Quotations cover anything from one supply for a demonstration desk to a unit per bench. Each quotation gives packing, delivery time and price for the requested quantity, and cables, bulbs, switches or other school chemistry lab equipment in India can be added.
Science Lab Supplies holds an Importer-Exporter Code and is able to ship to buyers in Tanzania, Uganda, the UAE, Saudi Arabia, Oman and the Philippines. Contact the team via the contact page, submit a list with the enquiry cart, or open the lab tender page for tender enquiries.
Frequently Asked Questions
What outputs does the power supply provide?
It provides regulated DC from 0 to 9 V at 2.5 A and a non-regulated AC output at a fixed 5 to 9 V, also at 2.5 A.
How is it protected against short circuits?
A thermal circuit breaker trips on electrical overload or short circuit, and a fuse gives further protection to the unit.
Who supplies the Power Supply Unit/ Block for DC?
Science Lab Supplies, a laboratory equipment supplier in India, sends it from Ambala to schools and colleges and through contractors, and can quote whole electricity benches.
How is the output voltage set?
Turn the rotary knob clockwise and stop when the value you need lines up with the index mark beside the knob.
