How Does It Compare with Other JLab Dual Supplies?
| Model | Outputs | Other listed details |
|---|---|---|
| This supply (EL-PSAT-1215) | 0–30 V positive and 0–30 V negative, each at 1 A | Stabilization ±0.1%; four meters |
| Dual Power Supply 15 Volt 500mA | 0–15 V positive and 0–15 V negative at 500 mA, plus fixed +5 V at 400 mA | Regulation ±0.1%; short-circuit protection and overload current limiting; two meters |

Choose this model when your circuits need adjustable rails of up to 30 V of either polarity and up to 1 A from each side. The 15 V model adds a fixed logic supply for mixed op-amp and digital work at lower current, and the fixed-voltage units suit trainers that always run at the same standard rails.
What Is the Dual Power Supply Used For?
A dual (split) supply provides a positive and a negative voltage about a common terminal. Operational amplifiers, complementary push-pull transistor stages and many analogue IC circuits need both polarities to swing their output above and below zero, which a single-output supply cannot provide. This unit serves those circuits, and the transistor experiments it is listed for, in B.Sc. electronics, engineering, diploma and ITI labs, where students set and read the supply voltages as part of the practical.
Before connecting a circuit, turn both outputs down to zero, wire the common terminal first, then the positive and negative leads, and raise the voltages to the values the circuit needs without exceeding the ratings of its ICs. Switch off before changing components. The four meters let students check the settings while they work; on dual supplies the usual arrangement is a voltmeter and an ammeter for each output, which you can confirm in the quotation.
What to Specify When Ordering
- Quantity — the minimum order is 10 units; one per bench or student group is typical for electronics practicals.
- Mains supply — the unit is listed for 220 V, 50 Hz; mention a different site supply in your enquiry.
- Leads and trainer boards — connecting leads are not named in this listing; add them, and any op-amp or transistor trainers, to the same enquiry.
Frequently Asked Questions
What outputs does this dual power supply provide?
Two: 0–30 V positive at 1 A and 0–30 V negative at 1 A. Both are variable from zero up to 30 V to suit the circuit under test.
Why do op-amp experiments need a dual supply?
Most op-amp circuits in teaching labs are designed to run from equal positive and negative rails, so the output can swing either side of zero volts. A dual supply provides both rails from one unit with a shared common terminal.
How stable are the outputs?
Stabilization is listed as ±0.1%, so the set voltages stay steady while students take readings.
How does it differ from the Dual Power Supply 15 Volt 500mA?
This model reaches 30 V on each side at 1 A and has four meters. The 15 V model goes to 15 V on each side at 500 mA, adds a fixed +5 V output at 400 mA and has two meters, with short-circuit protection stated on its page.
What details does an export quotation need?
Send the quantity, the destination country and port or city, your preferred delivery terms such as FOB or CIF, the mains voltage at site, any packing or labelling requirements, and the tender reference if one applies.
Who manufactures this dual power supply?
Jain Laboratory Instruments Pvt Ltd, trading as JLab, makes it at its works in Ambala, Haryana, India, and supplies it factory-direct.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, an electronics and physics lab equipment manufacturer in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. This dual supply comes from JLab’s own works rather than from a trading house, so colleges, technical institutes, dealers and importers deal directly with the maker; every unit is visually inspected before dispatch, and repeat orders are handled by the same team. JLab exports worldwide and ships to buyers in every region — for example Lesotho in Southern Africa, New Zealand in Oceania, Mexico in North America, Luxembourg in Western Europe and Costa Rica in Central America and the Caribbean. Tender details are on the JLab lab tenders page.
