AD-TW 401 GS, AD-TW 402 GS

Description

The separation converter serves the galvanic separation of impressed currents. It obtains its auxiliary energy form the input signal. The device is available as a single-channel (AD-TW 401 GS) or dual-channel (AD-TW 402 GS) version. The connection of an additional auxiliary voltage is not necessary. The output current is independent of the connected load up to the maximum value. The isolating transformer is also available as a TWB variant, which does not interrupt the input current if its output current is interrupted (bypass function).

AD-TW 401 GS, AD-TW 402 GS

Application

Economic separation of computer inputs, protection of sensitive units against potential delay, galvanic decoupling in complex measuring units.
