Variable Power Supply 0-25V
Product Code : JA-M-7892
The Variable Power Supply 0-25V (SKU JA-M-7892) is a bench supply for physics and electronics practicals that gives an AC or DC output continuously variable from 0 to 25 V with a rotary knob. It is continuously rated for a combined current of 8.5 A, shows the output voltage on a digital display and protects the secondary with a high-speed, resettable microprocessor-controlled trip. This variable AC DC power supply 0-25 V is manufactured in India by JaincoLab for school, college and university laboratories.
Specifications
The supply delivers 0 to 25 V AC or DC, continuously variable by a rotary knob, with an 8.5 A combined continuous rating, a digital voltage display switched between AC and DC by a toggle switch, a toroidal transformer with 40 A Schottky rectifier diodes and fan-free cooling.

Applications of the 0-25 V variable AC/DC power supply
The variable power supply is used wherever a practical needs an adjustable low-voltage source of either AC or DC, from Ohm's law and resistance experiments in secondary school to electromagnetism, heating and electronics work in college laboratories.
- Ohm's law and V-I characteristic practicals with a variable DC supply
- Powering electromagnets, solenoids and coils within the 8.5 A rating
- Supplying AC for transformer and induction demonstrations
- Heating-effect experiments with resistance wires and immersion heaters
- Running ray boxes, lamps and ticker timers that need a low-voltage supply

Frequently asked questions
What output does the power supply give?
It gives 0 to 25 V AC or DC, continuously variable by a rotary knob, with a combined continuous rating of 8.5 A.
How is the output voltage displayed?
A digital display shows the voltage for AC or DC, selected by a toggle switch.
How is the supply protected?
The secondary is protected by a high-speed, resettable microprocessor-controlled trip, the primary by a slow-blow fuse, and the transformer has thermal fuse protection.
Does it need a cooling fan?
No. Heavy-duty 40 A Schottky rectifier diodes and a toroidal transformer reduce weight and power waste, so no cooling fan is needed.
