Triac A.C. Line Switching with Power Supply Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-12885
Indian Lab Suppliers supplies the Triac A.C. Line Switching with Power Supply (Product ID: 12885) as part of its electronics engineering lab equipment range. It covers the ways a TRIAC can be used as an on/off AC power switch, rather than as a phase controller.
Quick Answer
Five circuits are built on the board: a line-triggered AC switch, a DC-triggered AC switch using the 12 V, 200 mA regulated supply, a self-latching line switch operated by two push buttons, a UJT-triggered switch using a 2N2646 relaxation oscillator and 1:1 pulse transformer, and the same UJT switch controlled by an NPN transistor from an external transducer. A 40 W lamp is the load, and a 230 V, 200 mA isolation transformer protects external instruments. The board runs from 230 V ±10%, 50 Hz mains and weighs about 5 kg.

Where This Is Used
Used alongside the Study of Triac and A.C.Phase Control (Product ID: 12882), which covers TRIAC phase control, and the Zero Voltage Switching with Power Supply (Product ID: 12920). The lamp circuit is at mains voltage, so change connections only with power off. Browse the full Electronics Engineering Lab Equipment range or related Electronics Lab Equipment products.
Frequently Asked Questions
How does a self-latching TRIAC switch work?
Once triggered by a push button, the circuit keeps supplying gate drive each half cycle until it is reset.
Can a sensor control the switch?
Yes, an NPN transistor lets an external transducer control the UJT trigger.
Is phase control included?
No; this board covers switching only.
