How Does It Compare with the JLab SCR Characteristics Apparatus?
| Model | Experiments | Supplies | Meters |
|---|---|---|---|
| This board (EL-AET-1459) | Gate (firing) characteristics, anode current characteristics, holding current, phase firing | 0–50 V DC anode, 0–3 V DC gate, 0–10 V AC anode | 3½-digit DC voltmeter (20 V / 200 V) and DC current meter (0–200 mA) |
| SCR Characteristics Apparatus | Anode current against anode–cathode voltage | 0–3 V DC/50 mA and 0–150 V DC | Three meters for voltage and current |
Choose this board when the practical covers gate firing, holding current and phase firing as well as the anode characteristic. The SCR Characteristics Apparatus plots anode current against anode–cathode voltage with a 0–150 V DC supply and three meters.
What Is the SCR Training Board Used For?
An SCR blocks current until a small gate current fires it; it then latches on and keeps conducting, without gate drive, for as long as the anode current stays above the holding current. The gate characteristic shows the gate voltage and current needed to fire the device, the anode characteristic shows its blocking and conducting states, and the holding current is the level at which it switches off again. With the AC anode supply the SCR turns off at the end of every half-cycle, so delaying the firing point within each half-cycle controls how much of the waveform reaches the load — the phase control used in light dimmers and motor speed controllers. These practicals belong to power electronics and analog electronics courses at diploma, BSc electronics and engineering level.
Frequently Asked Questions
What is the holding current of an SCR?
It is the smallest anode current that keeps the SCR conducting once the gate signal is removed. It is found by lowering the anode current until the SCR switches off.
Why does the board have both DC and AC anode supplies?
The DC supply is used for the static gate and anode characteristics and the holding-current test. The variable AC supply is used for the phase firing characteristics, because on AC the SCR switches off naturally as each half-cycle ends.
What other apparatus is needed?
A vacuum tube voltmeter and a 20 MHz cathode ray oscilloscope, used alongside the board’s own digital meters.
What information is needed for an export quotation?
The number of boards, the destination country and port or city, delivery terms such as FOB or CIF, and any packing, labelling or tender requirements.
Who manufactures the Silicon Controlled Rectifier board?
Jain Laboratory Instruments Pvt Ltd (JLab) makes it at its works in Ambala, Haryana, India.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a manufacturer of electronics and power electronics trainers in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The board is built at JLab’s own works rather than bought in from a trader, so colleges, institutes, dealers and importers buy it from the manufacturer itself, each board is visually inspected before dispatch, and repeat orders are handled by the same works. JLab exports worldwide and ships to buyers in every region — for example Barbados in Central America and the Caribbean, Thailand in Southeast Asia, Tunisia in North Africa, Senegal in West Africa and Bulgaria in Eastern Europe. Tender details are on the JLab lab tenders page.
