How Does It Compare with Other JLab Valve Experiment Power Supplies?
| Model | HT output | LT output | Bias | Meters |
|---|---|---|---|---|
| This supply (EL-PSAT-1205) — diode valve | 0–300 V, 30 mA | Variable, 1 to 6 (as listed), 3 A | Not listed | Two |
| Power Supply for Triode Valve Experiment Model | 0–300 V, 50 mA | 6.3 V, 3 A | 0–25 V, positive and negative | Three |
| Power Supply Model (triode) | 0–300 V, 30 mA | 6.3 V, 3 A | 0–20 V | Two |
| Power Supply for Tetrode and Pentode Valve Model | Two: 0–300 V at 50 mA and at 25 mA | 6.3 V, 3 A | 0–25 V, 5 mA | Five |
Choose this unit for diode work, where only anode voltage and current are measured and the filament supply is varied. The other supplies add a grid bias output, because triode, tetrode and pentode valves have a control grid.
What Is the Diode Valve Power Supply Used For?
In the diode valve experiment the LT (low-tension) supply heats the filament so that it emits electrons, and the HT (high-tension) supply makes the anode positive. Students raise the anode voltage in steps, read the anode current, and plot the characteristic curve: current rises while space charge limits it, then levels off at saturation. Repeating the run at other filament settings shows how saturation current depends on filament temperature — a standard thermionic-emission practical in college physics and engineering physics labs. Switch off the HT before changing connections, as its output reaches 300 V.
Frequently Asked Questions
What outputs does this power supply give?
An HT output of 0 to 300 V at 30 mA and a variable LT output listed as 1 to 6 at 3 A. The listing gives no unit for the LT range, so confirm it when you ask for a quote.
Does it include the diode valve?
This listing covers the power supply with its two meters. JLab lists a complete Diode Valve Characteristics Apparatus separately, linked below.
Who manufactures this power supply?
Jain Laboratory Instruments Pvt Ltd (JLab), at its Ambala works in Haryana, India.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a physics lab instrument and power supply manufacturer in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The unit is built in JLab’s own works, not bought from a trader, so colleges and dealers buy direct from the maker. JLab exports worldwide and ships to buyers in every region — for example Samoa in Oceania, Cameroon in Central Africa, Poland in Eastern Europe, Yemen in the Middle East and Kyrgyzstan in Central Asia. Tender buyers can refer to the JLab lab tenders page.
