Active Limiter with Power Supply and 1 meter (C.R.) Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-12281
Indian Lab Suppliers supplies the Active Limiter with Power Supply and 1 meter (C.R.) (Product ID: 12281) as part of its electronics engineering lab equipment range. It limits a signal at adjustable positive and negative levels with op-amps and compares this with a Zener limiter.
Quick Answer
The active limiter combines a summing amplifier, a unity-gain amplifier and an open-loop comparator, all on IC 741s, so the output follows the input until it reaches a set positive or negative limit and then stays there. The limits are adjustable for either polarity and are read on a 0-5 V DC voltmeter (65 mm rectangular). Comparing it with a Zener diode limiter shows the softer, fixed clipping of the Zener. Four IC 741s run from internal ±15 V and ±5 V DC supplies (50 mA each).
