Power and Differential Amplifier Trainer Manufacturer,Supplier and Exporter in India
Product Code : EL-AET-1476
Jlab Export is a leading Power and Differential Amplifier Trainer Manufacturer,and suppliers in India
Power and Differential Amplifier Trainer (code EL-AET-1476) is an analog electronics trainer for studying the working principle of two amplifier circuits: the differential amplifier and the class B push-pull power amplifier. Fixed and variable DC supplies and a sine-wave generator are built in, so the supply rails and the test signal come from one compact unit. It is built at JLab’s own works in Ambala, India.

What Is the Power and Differential Amplifier Trainer Used For?
A differential amplifier amplifies the difference between its two inputs while rejecting any signal common to both, which is why it forms the input stage of operational amplifiers. A class B push-pull stage splits each cycle between two transistors that conduct on alternate halves, so it runs more efficiently than a class A stage but shows crossover distortion near the zero crossing. Both circuits are core topics in analog electronics for diploma, BSc electronics and engineering students, and this trainer lets them be studied side by side.
Frequently Asked Questions
What test signal does the trainer provide?
An in-built sine-wave generator covering 800 Hz to 8 kHz, with its amplitude adjustable from 0 to 5 Vpp.
Which DC supplies are built in?
Four fixed rails of +12 V, −12 V, +5 V and −5 V, plus a variable DC supply of 0 to 1 V.
What mains supply does it need?
The trainer runs on 230 V ±10%, 50 Hz mains and is protected by a 350 mA slow-blow fuse.
What information is needed for an export quotation?
The number of trainers, the destination country and port or city, the delivery terms you prefer (for example FOB or CIF), any packing or labelling instructions, and the tender reference where one applies.
Who manufactures this amplifier trainer?
Jain Laboratory Instruments Pvt Ltd, trading as JLab, makes it in Ambala, Haryana, India, and supplies it directly as the manufacturer.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, an electronics and science lab equipment manufacturer in India, incorporated in 2017 and located on Hargolal Road, Ambala, Haryana. The trainer is produced in JLab’s own workshop instead of being sourced from a trader, so institutes, dealers and importers buy at source, each unit is visually checked before dispatch, and repeat orders are handled by the people who build it. The company is registered under CIN U29309HR2017PTC069123 and holds MSME Udyam registration UDYAM-HR-01-0003849 as a manufacturing enterprise. JLab exports worldwide and ships to buyers in every region, for example Denmark in Northern Europe, Senegal in West Africa, Libya in North Africa, Hungary in Eastern Europe and Fiji in Oceania. Tender buyers can find details on the JLab lab tenders page.
