High Voltage Power Supply Model Manufacturer,Supplier and Exporter in India

Product Code : EL-PSAT-1214
Jlab Export is a leading High Voltage Power Supply Model Manufacturer,and suppliers in India

High Voltage Power Supply Model (code EL-PSAT-1214) is an EHT (extra-high-tension) source for photomultiplier tubes and other radiation detectors, used in nuclear physics and radiation-measurement labs at colleges, universities and research institutes. Its output is continuously variable from 0 to 1500 V at a 1 mA load, in positive or negative polarity as required. It is made by Jain Laboratory Instruments Pvt Ltd (JLab) at its works in Ambala, India.

Specifications

What Is the High Voltage Power Supply Used For?

Photomultiplier tubes, Geiger–Müller tubes and proportional counters all need a stable high voltage before they can detect radiation, and their response depends on that voltage — a photomultiplier’s gain, for example, changes steeply as the voltage changes. This supply provides the EHT for experiments such as plotting the characteristic (plateau) curve of a GM tube, studying counting statistics, or running the photomultiplier of a scintillation detector in B.Sc. and M.Sc. nuclear physics practicals and in research set-ups. The ±0.5% regulation keeps the output steady as the load changes, and the LED display shows the setting with its polarity sign.

Photomultiplier bases are wired for either a positive or a negative supply, so state which one your detector needs. Turn the control to zero before switching on, raise the voltage slowly to the detector’s recommended operating value and never above its rated maximum. Voltages of this level are hazardous even at low current: connect or disconnect a detector only with the output turned down and the unit switched off, and use cables and connectors rated for the voltage. The current-limiting protection safeguards the supply against overload and short circuits; it does not replace safe handling.

What to Specify When Ordering

• Output polarity — positive or negative, to match your photomultiplier base or detector.
• Detector and cable — name the detector type and the connector your cable uses; the output connection is not stated in the listing, so the quotation can confirm it.
• Mains supply — the unit is listed for 220 V ±10%, 50 Hz; say so if your site uses a different supply.
• Quantity and companions — the minimum order is 10 units; add a GM tube, tube holder or counter to the same enquiry if you are equipping a full counting set-up.

Frequently Asked Questions

What output does this high voltage power supply give?
It gives a continuously variable output from 0 to 1500 V at a 1 mA load. The 1500 V figure is the maximum, so set the voltage to whatever your detector requires within that range.

What does EHT mean?
EHT stands for extra-high tension, the traditional name for a high-voltage DC supply of the kind used to operate photomultipliers, Geiger–Müller tubes and other radiation detectors.

Is the output positive or negative?
Either, as required. The listing offers positive or negative polarity, and the display has auto polarity, so state the polarity your detector needs when you order.

How stable is the output voltage?
Regulation is ±0.5% from no load to full load. Because detector response depends on the applied voltage, a regulated EHT source helps keep count rates and pulse heights consistent through a series of readings.

Can it be used with a Geiger–Müller tube?
It is listed as an EHT source for photomultipliers and other radiation detectors, a group that includes GM tubes. Set the output to the operating voltage in the tube’s data, stay within the supply’s 1500 V and 1 mA rating, and check that the polarity matches the tube connection.

What details does an export quotation need?
Send the quantity and polarity, the destination country and port or city, your preferred delivery terms such as FOB or CIF, the mains supply at site, any packing or labelling requirements, and the tender reference if you are buying against a tender.

Who manufactures this EHT supply?
Jain Laboratory Instruments Pvt Ltd, trading as JLab, manufactures it at its works in Ambala, Haryana, India, and quotes for it directly.

OEM Manufacturer

JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a manufacturer of physics, electronics and general laboratory equipment in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The High Voltage Power Supply Model is assembled at JLab’s own works, not sourced from a trader, which lets universities, research labs, dealers and importers buy factory-direct; each unit is visually inspected before it is packed, and repeat orders go straight to the manufacturer. JLab exports worldwide and ships to buyers in every region — for example Eswatini in Southern Africa, Uruguay in South America, Romania in Eastern Europe, Jamaica in Central America and the Caribbean, and Togo in West Africa. Tender buyers can refer to the JLab lab tenders page.
