AD-SW 3 GL

The AD-SW 3 GL is used to measure high AC currents, such as secondary currents from large current transformers (e.g. 0…5A AC). The device contains 3 measuring transformers for contactless measurement of all three phase currents. The lines to be measured are fed horizontally through the device. Three small signal outputs are available for evaluation, which represent the measured current. The three output signals are galvanically coupled but separated from the input and the supply with high isolation.
The AC sine wave voltage outputs, which follow the input signal 1:1 up to the maximum bandwidth of the device, can be customized.
The integrated wide range power supply allows a wide supply voltage range with low self-heating.
