How Does It Compare with Other JLab IC Supplies?
| Model | Outputs | Meters and other listed details |
|---|---|---|
| This supply (EL-PSAT-1216) | Variable ±0–15 V at 500 mA, plus fixed +5 V at 400 mA | Two meters; regulation ±0.1%; short-circuit protection |
| Dual Power Supply 0-30 Volt 1 Amp | Variable 0–30 V positive and negative, each at 1 A | Four meters; stabilization ±0.1% |
| Regulated Power Supply Model | Four fixed outputs: +5 V, −5 V, +12 V and −12 V, 300 mA maximum each | Listed for analog and digital ICs |
Pick this model for op-amp benches that need adjustable split rails plus a 5 V logic supply from one box. The 30 V model gives more voltage and current on each rail, and the fixed-output model suits IC trainers that always run on the same standard voltages.
What Is the Dual Power Supply Used For?
Op-amp circuits are normally powered from equal positive and negative rails so their output can swing either side of zero, and ±15 V is the classic supply for general-purpose op-amps. With both rails adjustable from zero, students can run inverting and non-inverting amplifiers, adders, integrators, differentiators, comparators and Schmitt triggers, and see how the output saturates as the rails are reduced. The fixed +5 V output covers common digital logic ICs, so a mixed analogue and digital circuit can run from one unit in B.Sc. electronics, engineering, diploma and ITI labs.
Turn the variable outputs down, connect the common terminal first and then the positive and negative leads, and switch off before rewiring. The short-circuit protection and current limiting help protect the supply and the circuit from wiring mistakes, which are common in student practicals, but they do not replace checking the circuit before switching on.
What to Specify When Ordering
- Quantity — the minimum order is 10 units; electronics labs usually plan one per bench.
- Mains supply — the unit is listed for 220 V, 50 Hz; mention a different site supply in the enquiry.
- Leads and trainers — connecting leads are not named in this listing; add them, and any op-amp experiment boards, to the same enquiry.
Frequently Asked Questions
What outputs does this dual power supply give?
Three: a continuously variable 0–15 V positive output and a 0–15 V negative output, both at 500 mA, and a fixed +5 V output at 400 mA.
Is it suitable for op-amp experiments?
Yes — it is listed for operational amplifiers and other IC experiments. The adjustable split rails power the op-amp, and the fixed 5 V output is available for any logic ICs in the same circuit.
What protection does it have?
Short-circuit protection and overload current limiting are built in, and regulation is ±0.1%. That makes it forgiving of the wiring errors students make while building circuits.
How does it differ from the Dual Power Supply 0-30 Volt 1 Amp?
The 30 V model reaches 30 V on each rail at 1 A and has four meters but no fixed 5 V output listed. This model is limited to 15 V at 500 mA per rail, adds the fixed +5 V supply and has two meters.
What should I send for an export quotation?
The quantity, destination country and port or city, preferred delivery terms such as FOB or CIF, the mains voltage at site, any packing or labelling instructions, and the tender reference if one applies.
Who manufactures this power supply?
Jain Laboratory Instruments Pvt Ltd, trading as JLab, builds it at its works in Ambala, Haryana, India, and sells it directly as the manufacturer.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a maker of electronics, physics and general laboratory equipment in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. This dual supply is produced at JLab’s own works, not bought from a trader, so institutions, dealers and importers buy at source; each unit is visually inspected before packing, and repeat orders come from the same works. The company holds MSME Udyam registration UDYAM-HR-01-0003849 (manufacturing enterprise) and Importer-Exporter Code 3317504552. JLab exports worldwide and ships to buyers in every region — for example Croatia in Southern Europe, Estonia in Northern Europe, Fiji in Oceania, Malaysia in Southeast Asia and Poland in Eastern Europe. Buyers working to a tender can see the JLab lab tenders page.
