Mono-Stable Multivibrator with power supply Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-12141
Indian Lab Suppliers supplies the Mono-Stable Multivibrator with power supply (Product ID: 12141) as part of its electronics engineering lab equipment range. It is a training board for studying a transistor monostable (one-shot) multivibrator that gives one timed pulse for each trigger.
Quick Answer
The circuit uses two NPN transistors and a potentiometer, powered by an IC-regulated ±9 V DC, 50 mA supply. A square wave from an external oscillator triggers it, and students produce a pulse train whose repetition rate follows the input while the pulse width is set by the R-C timing network. Waveforms are traced at various points in the circuit on an oscilloscope.

Where This Is Used
Studied with the Free Running Multivibrator (Astable) with power supply (Product ID: 12139) and the Bi-Stable Multivibrator with power supply (Product ID: 12140); the same one-shot action is shown with an IC on the Timer Applications IC-555 No. 1 with power supply and Oscillator (Product ID: 12190). The board is mains powered; switch off before changing leads. Browse the full Electronics Engineering Lab Equipment range or related Electronics Lab Equipment products.
Frequently Asked Questions
How many stable states does a monostable have?
One; after a trigger it returns to that state after a fixed time.
What sets the pulse width?
The R-C timing network in the circuit.
Is the trigger source built in?
No, an external sine/square wave oscillator is used.
