Triac Characteristics Apparatus Manufacturer,Supplier and Exporter in India
Product Code : EL-SCD-1097
Jlab Export is a leading Triac Characteristics Apparatus Manufacturer,and suppliers in India
Triac Characteristics Apparatus (code EL-SCD-1097) is a panel trainer for studying the main-terminal (MT) characteristics of a triac with a gate signal applied, as practised in power-electronics and physics laboratories. The triac sits on the panel with two DC regulated power supplies, 0–25 V and 0–5 V, and three round meters for voltage and current. It is made by Jain Laboratory Instruments Pvt Ltd (JLab) at its works in Ambala, India.

How Does It Compare with Other JLab Thyristor Apparatus?
| Apparatus | Device | Supplies (as listed) | Meters |
|---|---|---|---|
| This triac apparatus (EL-SCD-1097) | Triac | 0–25 V DC / 100 mA and 0–5 V DC / 200 mA | Three round meters |
| Diac Characteristics Apparatus | Diac | 0–50 V DC / 100 mA | Two round meters |
| SCR Characteristics Apparatus | SCR | 0–3 V DC / 50 mA and 0–150 V DC | Three meters |
Choose the triac unit when the practical is about a bidirectional, gate-controlled switch. The diac unit has no gate and shows only breakover in both directions, while the SCR unit covers the one-directional thyristor; together the three make up a complete thyristor bench.
What Is the Triac Characteristics Apparatus Used For?
A triac is a three-terminal thyristor (two main terminals and a gate) that can conduct in both directions once it is triggered, which is why it is used to switch and control AC power in lamp dimmers, fan regulators and heater controls. With this apparatus students set a gate signal, raise the voltage across the main terminals, and record the meter readings until the triac switches on. Repeating the run at different gate settings shows how the gate signal controls the point at which the triac switches on, and reversing the main-terminal polarity at the terminals gives the characteristic in the opposite quadrant.
The experiment suits B.Sc. physics and electronics practicals, diploma and engineering power-electronics labs and ITI electronics courses. In a typical triac practical one supply drives the main-terminal circuit and the other sets the gate current; keep both at zero while wiring and switch off before changing polarity.
What to Specify When Ordering
- Quantity — minimum 10 units; state whether the diac and SCR units should be quoted at the same time.
- Connecting leads and spare triacs — not stated in the listing, so list them in your enquiry if needed.
- Mains voltage at your lab and the delivery destination for export orders.
Frequently Asked Questions
Which characteristics can be plotted with this triac apparatus?
The main-terminal (MT) characteristics with a gate signal applied: current through the triac against the voltage across its main terminals, for different gate settings and for both polarities.
What supplies and meters does it have?
Two DC regulated supplies, 0–25 V DC at 100 mA and 0–5 V DC at 200 mA, and three round meters for voltage and current. The supplies and the triac are wired to terminals on the panel.
Can it be used alongside the diac apparatus?
Yes. The Diac Characteristics Apparatus is a separate listing in the same series; a diac is the usual trigger device for a triac in AC phase control, so many labs run the two practicals one after the other.
What details are needed for an export quotation?
Quantity, destination country and port or city, delivery terms (for example FOB or CIF), any packing or labelling instructions, and a tender reference where relevant.
Who manufactures it?
JLab (Jain Laboratory Instruments Pvt Ltd) makes the apparatus at its Ambala works in Haryana, India, and supplies it factory-direct.
OEM Manufacturer
The apparatus is designed and built by Jain Laboratory Instruments Pvt Ltd, which trades as JLab: a physics and electronics lab equipment manufacturer in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. Because it is made in JLab’s own works and not bought in from a trader, universities, polytechnics, dealers and importers buy direct, each unit is visually checked before it is packed, and repeat orders are handled by the manufacturer. JLab exports worldwide and ships to buyers in every region — for example Zimbabwe in East Africa, Algeria in North Africa, Vanuatu in Oceania, Tajikistan in Central Asia and Namibia in Southern Africa. For institutional purchasing, see the lab tenders page.
