How Does It Compare with Other JLab Power Supplies?
| Model | Outputs as listed | Other listed details |
|---|---|---|
| This power supply (EL-SLE-5793) | 0–12 V AC and full-wave rectified 0–12 V DC, in 2 V steps | 220–240 V, 50/60 Hz mains; overload protection on both outputs |
| 0-12V 6A Ac/Dc Low Voltage Power Supply Unit | AC in steps of 1.5, 3, 6, 9 and 12 V; DC continuously variable 0–12 V | AC and DC usable together up to 6 A; digital display of DC voltage |
| AC/DC Power Supply | AC and stabilized DC, 1 to 15 V in 1 V steps, up to 10 A | 150 VA; galvanically isolated, short-circuit-proof outputs; 4 mm jacks |
| Regulated Variable Power Supply | Regulated DC 0–30 V, 1 A | Digital panel meter; short-circuit protection |
Choose this unit for general class practicals that need a few fixed low voltages, AC or DC, from one box. The 6 A unit adds continuously variable DC and a display, the 10 A model suits heavier loads, and the regulated 0–30 V supply suits electronics work that needs a steady DC voltage.
What Is the Power Supply Used For?
A school low-voltage supply replaces banks of cells for experiments that need more voltage or a steady source. The stepped AC and DC outputs suit Ohm’s law and resistance work in class 10 and class 12 electricity practicals, low-voltage lamps and heaters, electromagnets and solenoids, electrolysis, and demonstrations that need AC, such as transformer and induction experiments. The DC output is listed as full-wave rectified and the listing does not mention smoothing or regulation, so it is well suited to lamps, heating, electrolysis and electromagnets; for electronic circuits that need a steady, regulated DC voltage, use a regulated supply instead.
Start with the selector at the lowest step, connect the circuit, then switch on and increase the voltage. Stay within the current your circuit and meters can take, and if the overload protection operates, switch off and check the circuit for a short before using it again. Keep the unit dry and do not cover it while it is in use.
What to Specify When Ordering
- Quantity — the minimum order is 10 units.
- Output current — tell us the current your experiments draw so JLab can confirm the rating with the quotation.
- Mains plug — state the plug type used in your country.
- Leads and meters — connecting leads, ammeters and rheostats are separate catalogue items.
Frequently Asked Questions
What voltages does the power supply give?
0 to 12 V AC and 0 to 12 V DC, each selectable in 2 V steps. The DC output is produced by full-wave rectification.
What mains supply does it need?
220–240 V at 50 or 60 Hz. Tell JLab your plug type when you ask for a quotation.
What is the maximum output current?
The current rating is not stated in this listing. Both outputs have overload protection; tell JLab the current your experiments need and the rating will be confirmed in the quotation.
Is the DC output smooth enough for electronics?
The listing describes it as full-wave rectified and does not mention smoothing or regulation. That suits lamps, heaters, electrolysis and electromagnets; for sensitive electronic circuits choose a regulated DC supply.
How does it differ from the 0-12V 6A AC/DC unit?
This supply gives AC and DC in 2 V steps. The 6 A unit is listed with AC in steps up to 12 V, continuously variable DC from 0 to 12 V, a digital DC voltage display and a 6 A combined load.
Who manufactures this power supply?
Jain Laboratory Instruments Pvt Ltd, trading as JLab, makes it at its works in Ambala, Haryana, India, and quotes for it directly as the manufacturer.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, an Indian maker of school electrical apparatus and laboratory equipment, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The power supply is built at JLab’s own works rather than bought from a trader, so schools, colleges, dealers and importers deal with the manufacturer directly; each unit is visually inspected before dispatch, and repeat orders are handled by the same works. JLab exports worldwide and ships to buyers in every region — for example Myanmar in Southeast Asia, Hong Kong in East Asia, Mauritius in East Africa, Panama in Central America and the Caribbean and the UK in Western Europe. Tender details are on the JLab lab tenders page.
Apparatus to Use with the Power Supply
- Lamps — 6 V and 12 V, 5 W low-voltage lamps.
- Lenz’s Law Apparatus — a switched solenoid for 12 V AC/DC; check its current needs against the supply rating.
- Rheostats (Nichrome Type) — for setting the current in a circuit.
- D.C. Ammeter — for measuring the current drawn from the DC output.
