ISG-A124 Infrared Photoelectric Amplifier

Manufacturer: Pantron Instruments, GmbH
Category: Infrared Photoelectric Amplifiers

Automatic amplifiers are the further development of standard amplifiers. They work without adjustment and operate by switching on the power supply to the correct range, adjusting the transmit power to an optimum, and by constantly regulating the effects of disturbances. The amplifier works with modulated infrared light, which enables a high degree of light immunity to ambient light.
