Power Supply for Triode Valve Experiment Model Manufacturer,Supplier and Exporter in India
Product Code : EL-PSAT-1207
Jlab Export is a leading Power Supply for Triode Valve Experiment Model Manufacturer,and suppliers in India
Power Supply for Triode Valve Experiment Model (code EL-PSAT-1207) is a stabilised, mains-operated supply for studying triode valves. It gives HT 0 to 300 V at 50 mA, LT 6.3 V at 3 A and a grid bias of 0 to 25 V of either polarity, with three meters for HT voltage, HT current and bias voltage, so HT and grid readings come from the unit itself. It is made by Jain Laboratory Instruments Pvt Ltd (JLab) at its works in Ambala, India.

How Does It Compare with Other JLab Valve Supplies?
| Model | HT output | Bias | Meters |
|---|---|---|---|
| This supply (EL-PSAT-1207) | 0–300 V, 50 mA; stabilised | 0–25 V, positive and negative | Three |
| Power Supply Model (triode) | 0–300 V, 30 mA | 0–20 V | Two (HT only) |
| Power Supply for Tetrode and Pentode Valve Model | Two HT outputs, 0–300 V at 50 mA and 25 mA; stabilised | 0–25 V, 5 mA | Five |
All three have an LT output of 6.3 V at 3 A. Pick this unit when triode work needs bias of both polarities and a metered grid voltage; the Power Supply Model is the simpler triode option, and the tetrode and pentode supply adds the second HT output that screen-grid valves need.
What Is the Triode Valve Power Supply Used For?
A triode’s grid controls the anode current, and the experiment maps that control: plate characteristics at fixed grid voltages, then mutual characteristics at fixed anode voltage, from which college and university students find plate resistance, transconductance and amplification factor. A stabilised HT holds the anode voltage steady as load and mains change, giving cleaner curves. Turn the HT to zero and switch off before changing connections.
Frequently Asked Questions
What outputs and meters does it have?
HT 0 to 300 V at 50 mA, LT 6.3 V at 3 A and bias 0 to 25 V of either polarity, with three meters; it runs on 220 V, 50 Hz.
Why is the bias available in both polarities?
A triode is normally run with a negative grid; the positive range lets students extend the curves into the region where grid current flows. The listed bias range is 0 to 25 V in both directions.
Is the triode valve part of this listing?
No; the Triode Valve Characteristics Apparatus, linked below, is a separate item.
Who manufactures this power supply?
Jain Laboratory Instruments Pvt Ltd (JLab) makes it in Ambala, Haryana, India, and quotes for it as the manufacturer.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a manufacturer of physics and electronics teaching equipment in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The supply is assembled in JLab’s own works, so universities and dealers deal with the maker directly. JLab exports worldwide and ships to buyers in every region — for example Colombia in South America, Turkey in the Middle East, the USA in North America, Papua New Guinea in Oceania and Myanmar in Southeast Asia. See the JLab lab tenders page for tender enquiries.
