Supply Isolation Amplifier
AD-STV 810 GS


back to products

  Description

The separation amplifier of type family AD-STV 810 serves the galvanic separation, conversion and amplification of unipolar signal sizes. The very high frequency range allows direct current as well as fast current transfers. Input, output and the supply voltage are galvanically separated from each other. The output signal is independent of the connected load up to a maximum value. The limit frequency of the amplifier can be set at the front as an option.

  Application

Recording, galvanic 3-way separation, conversion and amplification of unipolar measuring sizes (voltage or current).
