SCR TESTER
The SCR tester circuit is designed to evaluate the functionality of Silicon Controlled Rectifiers (SCRs) by facilitating connections to their cathode, anode, and gate terminals. The circuit typically includes a power supply, a microcontroller or comparator for testing, and visual indicators such as LEDs to signal the SCR's operational status.
To begin the testing process, the SCR's cathode terminal is connected to the designated cathode terminal of the tester, while the anode terminal is linked to the anode terminal of the tester. The gate terminal of the SCR is connected to the gate terminal of the tester.
Upon activation, the tester applies a specific voltage across the anode and cathode to determine if the SCR is in a conductive state. The gate terminal is then energized to trigger the SCR. If the SCR conducts, the circuit will illuminate an LED indicator or display a signal on an LCD screen, confirming that the SCR is functional. Conversely, if the SCR does not conduct when triggered, the tester will indicate a fault.
In addition to basic functionality testing, the circuit may incorporate features for measuring the gate trigger voltage and the holding current, providing further insights into the SCR's performance characteristics. This comprehensive testing capability ensures that the SCRs are reliable for use in various applications, such as in power control and switching circuits.SCR TESTER CIRCUIT The Device under test cathode, anode and gate are connected to the unit`s CATHODE, ANODE and GATE terminals,.. 🔗 External reference
