|---|---|---|
| This board (EL-AET-1461) | Gate characteristics in four modes; terminal characteristics in modes I+ and III+; static switch, AC control with an AC signal, holding current | 0–70 V and 0–3 V regulated DC; 55 V and 7 V fixed AC; external oscilloscope and digital meters |

| Triac and AC Phase Control | Operation in all four modes; gate control with NPN and PNP transistors; phase control with a DIAC trigger; light dimmer; RFI suppression | Built-in TRIAC and DIAC; 40 W lamp load; RF choke and capacitor for the RFI filter |
| Triac AC Line Switching | Five experiments with the triac as an AC mains power switch, including line, DC and UJT triggering | Isolation transformer, 230 V AC at 250 mA; 12 V DC at 250 mA; 40 W lamp load |
Choose this board when the course calls for TRIAC gate characteristics in all four triggering modes and a holding-current measurement. The Triac Characteristics Apparatus has its own three round meters for an MT characteristic study, Triac and AC Phase Control covers DIAC-triggered phase control and RFI suppression, and Triac AC Line Switching uses the triac as a mains power switch with a lamp load.
What Is the Triac Training Board Used For?
A TRIAC is a bidirectional thyristor: once a gate signal triggers it, it conducts in either direction between its main terminals T1 and T2, and it keeps conducting until the main current falls below the holding current. That is why it is the usual switching device in AC lamp dimmers, fan regulators and heater controls. On this board students plot its gate characteristic for each combination of T2 and gate polarity, trace the terminal characteristic in modes I+ and III+, and then use the device as a DC-controlled static switch and to control AC with an AC signal — practicals in power electronics and analog electronics courses at diploma, BSc and engineering level.
What to Specify When Ordering
- Number of boards for your power electronics or analog electronics lab.
- Any of the other apparatus you need, which can be added to the same enquiry.
- Companion thyristor trainers for the same course, such as the DIAC and SCR boards linked below.
Frequently Asked Questions
What are the four TRIAC triggering modes?
They are named by the polarity of T2 and of the gate, both measured with respect to T1. In mode I+ T2 and the gate are both positive; in mode I− T2 is positive and the gate negative; in mode III+ T2 is negative and the gate positive; in mode III− both are negative. The board covers the gate characteristics in all four.
What is the holding current?
The holding current, IH, is the smallest main-terminal current that keeps a TRIAC conducting once it has been triggered and the gate signal is removed; if the current falls below it, the device turns off. Measuring it is one of the applications studied on this board.
Are the oscilloscope and meters part of the board?
No. A 20 MHz cathode ray oscilloscope and three 3½-digit digital DC meters are needed as other apparatus. They are separate items that can be quoted on the same enquiry.
How is a TRIAC different from a DIAC?
A DIAC has no gate: it switches on in either direction when the voltage across it exceeds its break-over voltage. A TRIAC is switched on by a gate signal, and in many AC phase-control circuits a DIAC supplies that trigger pulse.
What information is needed for an export quotation?
Send the number of boards, the destination country and port or city, delivery terms such as FOB or CIF, any packing or labelling instructions, and a tender reference if one applies.
Who manufactures the Training Board for Triac?
Jain Laboratory Instruments Pvt Ltd (JLab) builds it at its works in Ambala, Haryana, India.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, an Indian manufacturer of electronics trainers and laboratory instruments, incorporated in 2017 and located on Hargolal Road, Ambala, Haryana. This TRIAC board is produced at JLab’s own works and is not bought in from a trader, so polytechnics, colleges, dealers and importers order it straight from the maker; each board is visually inspected before dispatch, and repeat orders and spares are handled by the same works. JLab exports worldwide and ships to buyers in every region — for example Mexico in North America, Guyana in South America, Luxembourg in Western Europe, Bhutan in South Asia and Tajikistan in Central Asia. For tender enquiries, see the JLab lab tenders page.
