AD-TV 452 GVC, AD-TV 454 GVF

Description

The multiplier isolation amplifiers AD-TV 452 GVC and AD-TV 454 GVF are used for galvanic isolation, amplification and transformation, or adjustment of analog measurement signals with simultaneous multiplication of the input signal. The compact housing contains 2 or 4 completely independent output channels, which are galvanically isolated from the input, the supply voltage and the other outputs. The signal types at the input and the output can be selected via clamps. At the front side there are spindle trimmers (Zero Z1..2/4 / Span S1..2/4) for direct adjustment. The efficient wide range power supply allows operation in a wide supply voltage range with low heat generation.
