Power Supply, Smoothed
Power Supply, Smoothed (Product Code: SLE/PHY/273) is a stepped low-voltage bench supply with a specially smoothed output, used to power electronics circuits in school and college laboratories. It delivers 2 to 12 V AC or DC in 6 steps at 5 A from a 230 V AC, 50 Hz mains input, and it is the smoothed version of the Power Supply, Stepped. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

What Is the Smoothed Power Supply Used For?
Transistors, integrated circuits, LEDs and logic gates behave best on a steady DC voltage. A plain rectified supply carries ripple that can make an amplifier hum, upset a timer circuit or make meter readings drift, so this unit adds smoothing to the stepped design. That makes it a practical low-voltage source for electronics practicals such as transistor characteristics, rectifier circuits and simple amplifier work.
Choose the lowest step that will run the circuit, switch off before moving to a different step, and keep the total load within the 5 A rating. For general electricity work with lamps and motors, where ripple does not matter, the standard stepped supply is an alternative, so many laboratories keep both on the shelf.
What to Specify When Ordering
- Smoothed output (this item) or the standard Power Supply, Stepped.
- Number of units per bench or student group.
- Confirmation that your mains matches the 230 V AC, 50 Hz input.
- Leads, meters or components to be quoted with it.
Supplier
ScienceLab, the trading name of Jain Scientific Equipments Private Limited, supplies the Power Supply, Smoothed from Ambala, Haryana, India. The company sources both the smoothed and the standard stepped versions of this supply, so a laboratory can equip its electronics and general electricity benches from one quotation.

Frequently Asked Questions
What output does the Power Supply, Smoothed give?
The Power Supply, Smoothed gives 2 to 12 V AC or DC, selected in 6 steps, at a current of 5 A. Its output is specially smoothed, which makes it better suited to electronics circuits than an ordinary stepped supply.
How does the Power Supply, Smoothed differ from the Power Supply, Stepped?
The Power Supply, Smoothed is the same unit as the Power Supply, Stepped, but its output is specially smoothed for electronics applications. Choose the smoothed version for transistors and other sensitive circuits, and the stepped version for general electricity work.
What mains input does the Power Supply, Smoothed need?
The Power Supply, Smoothed runs from a 230 V AC, 50 Hz mains input. If your laboratory uses a different mains voltage or frequency, tell us through the contact page before ordering so we can confirm suitability.
What are the dimensions of the Power Supply, Smoothed?
The Power Supply, Smoothed measures 220 x 110 x 145 mm (W x H x D), a compact bench-top size that leaves room for circuit boards, components and meters on a student workstation.
Who supplies the Power Supply, Smoothed?
The Power Supply, Smoothed is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, Haryana, India. The company sources the unit and quotes it for schools, colleges, dealers and importers in India and international markets.
What should a quotation request for the Power Supply, Smoothed include?
