AD-BV 20 GVC

Description

The burden amplifier AD-BV 20 GVC serves the power amplification (burden increase) in application with high current loop resistance, i.e. line resistance. The burden amplifier is switched directly behind a present current source (i.e. separation amplifier AD-TV 22 GL), whereby the energy of the current source is also used. The device output of the total device chain is optimally utilised. The galvanic signal separation of the series separation amplifier continues to be realised.

AD-BV 20 GVC

Application

In applications where isolation amplifiers with e.g. max. 500 Ohm can no longer provide the required load voltage to bridge high line resistances.
