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 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 school and college circuits up to 9 V. Science Lab Supplies quotes the unit from Ambala, India, for schools, colleges, training institutes, tender contractors and distributors.
Specifications
The power block's outputs, controls and protection are itemised row by row below. In short, the DC output is regulated over 0–9 V at 2.5 A, the AC output is non-regulated at a fixed voltage from 5 to 9 V and 2.5 A, and the voltage is chosen by turning the knob clockwise to the index mark.

Applications and Experiments for the DC Power Supply Unit
A regulated 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, connected with Cables with Clips.
- Resistors in series and parallel: powering circuits for Class 10 and Class 12 activities.
- Magnetic effects of current: driving the Set of Coils with Removable Iron Core to compare fields from 300, 600 and 1200 turns.
- ITI and vocational electrical training: bench supply for circuits and component testing.
Connect and switch the unit 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, thermal circuit breaker, fuse and illuminated rocker switch. Connecting cables, meters and circuit components are separate items and can be listed on the same 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. To price one supply or a unit for every bench, describe the requirement on the contact page, line up cables and components beside it in the enquiry cart, or refer to the lab tender page for formal purchasing.
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 voltage from 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. Let the breaker reset and find the fault before switching on again.
Who supplies the Power Supply Unit/ Block for DC?
It is available through Science Lab Supplies, a laboratory equipment supplier in India working from Ambala, which can quote one unit or whole electricity benches for schools, colleges and contractors.
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; the lit rocker switch confirms the unit is on.
