Window Detector with power supply and 1 meter (C.R.) Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-12276
Indian Lab Suppliers supplies the Window Detector with power supply and 1 meter (C.R.) (Product ID: 12276) as part of its electronics engineering lab equipment range. It signals when an input voltage lies inside a set window between a lower and an upper threshold.
Quick Answer
Two IC 741 comparators, one inverting and one non-inverting, check the input against a lower and an upper reference. Their outputs are combined so that the LEDs show whether the input is below, inside or above the window. Students set the thresholds, vary the input and read levels on a 0-15 V DC voltmeter (65 mm rectangular) to find the switching points. An internal ±15 V DC, 50 mA supply powers the board, and nothing else is required.
