SCR Application Trainer Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-12935
Indian Lab Suppliers supplies the SCR Application Trainer (Product ID: 12935) as part of its electronics engineering lab equipment range. It is a single board that brings together the common SCR, TRIAC, UJT and DIAC application circuits, from a DC circuit breaker to a temperature controller.
Quick Answer
Experiments are grouped as: DC circuit breaker (SCR turn-off under varying loads, over-voltage and over-current trip); lamp flashers (symmetrical SCR DC flasher, high-power AC flasher); half-wave and full-wave AC phase control; UJT relaxation oscillator; thyristor alarms (make-to-operate, break-to-operate, tamper-proof burglar alarm); time-delay relay (delayed turn-on and auto turn-off of a DC load); light-operated switch and relay; temperature control of an external load and of the internal oven; SCR and TRIAC illumination control; a 555 timer; and an SCR emergency light. The board carries three IC-regulated DC supplies, an AC supply and isolation transformer, timer, op-amp and quad 2-input NAND ICs, a pulse transformer, battery, DC relay, oven with its own supply, 0-110 °C thermometer, 4 SCRs, a TRIAC, DIAC, 2 UJTs, LDR, thermistor, buzzer and 230 V 40 W and 12 V 5 W lamps. It runs from 230 V ±10%, 50 Hz mains.

Where This Is Used
Covers in one unit the circuits of single-topic boards such as the S.C.R. DC Circuit Breaker (Product ID: 12893) and the Thyristor Alarms with Power Supply (C.R.) (Product ID: 12887). The oven gets hot and some circuits run at mains voltage: switch off before rewiring and use isolated or differential oscilloscope probes rather than an unearthed oscilloscope.
