Power Supply for Tetrode and Pentode Valve Model Manufacturer,Supplier and Exporter in India
Product Code : EL-PSAT-1209
Jlab Export is a leading Power Supply for Tetrode and Pentode Valve Model Manufacturer,and suppliers in India
Power Supply for Tetrode and Pentode Valve Model (code EL-PSAT-1209) is a dual stabilised supply for tetrode and pentode valve experiments, with two HT outputs of 0 to 300 V (one at 50 mA, one at 25 mA), a bias output of 0 to 25 V at 5 mA and an LT output of 6.3 V at 3 A. Both supplies are listed as stabilised to ±1%, five meters are fitted, and it works on 220 V, 50 Hz. It is made by Jain Laboratory Instruments Pvt Ltd (JLab) at its works in Ambala, India.

How Does It Compare with the JLab Triode Supplies?
| Model | HT outputs | Bias | Meters |
|---|---|---|---|
| This supply (EL-PSAT-1209) | Two: 0–300 V at 50 mA and 0–300 V at 25 mA | 0–25 V, 5 mA | Five |
| Power Supply for Triode Valve Experiment Model | One: 0–300 V at 50 mA | 0–25 V, positive and negative | Three |
| Power Supply Model (triode) | One: 0–300 V at 30 mA | 0–20 V | Two |
All three give LT 6.3 V at 3 A. The second HT output is what sets this unit apart: tetrodes and pentodes need a separate supply for the screen grid, which a single-HT triode supply cannot provide.
What Is the Tetrode and Pentode Valve Power Supply Used For?
A tetrode adds a screen grid between the control grid and the anode; a pentode adds a further suppressor grid. In the usual set-up the LT heats the valve, one HT output feeds the anode, the other holds the screen grid at a fixed positive voltage, and the bias output sets the control grid. Students then plot anode current against anode voltage: the tetrode curve shows a dip caused by secondary emission from the anode, while the pentode’s suppressor grid removes it. These are standard college and university electronics practicals; switch off before changing connections.
Frequently Asked Questions
Why does this supply have two HT outputs?
Tetrode and pentode valves need one voltage for the anode and another for the screen grid. The two listed outputs are both 0 to 300 V, one rated 50 mA and the other 25 mA.
Is the valve included?
No valve is named in this listing; the Tetrode and Pentode Valve Characteristics Apparatus, which has its own valve, is linked below.
Who manufactures this power supply?
Jain Laboratory Instruments Pvt Ltd (JLab), at its own works in Ambala, Haryana, India.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, an Indian maker of physics, electronics and electrical lab equipment, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. This dual supply is built in JLab’s own works, so colleges and dealers buy direct from the maker. JLab exports worldwide and ships to buyers in every region — for example Bangladesh in South Asia, Benin in West Africa, Brunei in Southeast Asia, Kazakhstan in Central Asia and the Czech Republic in Eastern Europe. Tender details are on the JLab lab tenders page.
