AD-TV 380 GA


The isolating amplifier of the type family AD-TV 380 serves the galvanic isolation, conversion and amplification of analog signal magnitudes. By using the front mounted zero and gain trimmers, the output signal can be adjusted.The output is designed for currents up to 200 mA. Input, output and supply voltage are galvanically isolated from each other. The output signal is independent of the connected load up to a maximum value.

AD-TV 380 GA


For registration, galvanic 3-way separation, conversion and amplification of bi-polar measuring magnitudes (voltage or current)
