SCR Characteristics Apparatus Manufacturer,Supplier and Exporter in India
Product Code : SCL-EAE-11323
The apparatus provides a structured experimental platform for examining an SCR in forward-blocking, triggered-conduction and reverse-blocking conditions. An SCR has an anode, cathode and gate. A suitable gate signal initiates conduction when the device is correctly forward biased.
Students can record anode voltage, anode current and gate-control observations to plot characteristic curves. The experiment also introduces latching current and holding current. Exact SCR ratings, meter ranges, power-supply outputs, circuit protection and panel construction must be confirmed before ordering.
Key Features
SCR V-I characteristic study: Supports observation of blocking and conducting operating regions.
Gate-triggering experiment: Demonstrates how a gate signal switches a forward-biased SCR into conduction.
Latching-current study: Helps learners investigate the minimum current needed to maintain conduction after triggering.
Holding-current study: Supports observation of SCR turn-off as anode current falls below the holding level.
Practical measurements: Enables tabulation and graphical analysis of voltage and current readings.
Power-electronics training: Connects semiconductor theory with controlled-rectifier applications.
Supervised laboratory format: Suitable for instructor demonstrations and repeatable student practicals.

How to Use the SCR Characteristics Apparatus
Identify the SCR anode, cathode and gate connections.
Confirm the approved SCR, supply and meter ratings.
Keep all power sources switched off while connecting the circuit.
Set the supply and gate controls to their minimum positions.
Apply forward voltage gradually without a gate signal and record observations.
Apply the permitted gate signal and observe the transition into conduction.
Record anode voltage and current at selected operating points.
Reduce anode current gradually to investigate holding behaviour.
Switch off the supply before altering or removing connections.
Safety note: Use current limiting and remain within the confirmed gate, anode and power-dissipation ratings. Incorrect polarity or excess current can permanently damage the SCR.
Care and Maintenance
Keep the panel, terminals, meter covers and leads clean and dry.
Inspect connectors and insulation before every experiment.
Return all controls to minimum before switching off or storing the apparatus.
Store it in a dry, dust-controlled laboratory cabinet.

Frequently Asked Questions
What is an SCR Characteristics Apparatus used for?
It is used to study SCR voltage-current characteristics, gate triggering, latching current and holding current.
What is an SCR?
An SCR is a three-terminal semiconductor switching device with an anode, cathode and gate. It conducts after suitable forward bias and gate triggering.
How is an SCR triggered?
A suitable gate current is applied while the anode is positive relative to the cathode. The exact triggering level depends on the SCR rating.
What is holding current?
Holding current is the minimum anode current required to keep the SCR conducting after it has switched on.
Can students plot the SCR V-I curve?
Yes. Students can record voltage and current observations and plot the corresponding characteristic curve.
Are meters and a power supply included?
The supplied configuration was not confirmed. Verify the meters, power arrangement, leads and manual in the quotation.
