Precise & dynamic current measurement up to 50 A

 The ADQ-412 CompactPCI board serves for PC based current measurement up to 50 A. 2 isolated analog input channels with the current measurement ranges ±25 mA and ±50 A are provided. The relay controlled change-over between the both shunts (10 Ω / 5 mΩ) is typically handled by your application without interrupting the circuit.

A hardware comparator automatically switches into the 50 A range as soon as the 25 mA range is exceeded by more than 12.5%. This protection mechanism works independently from operating system and application software. An appropriate interrupt event will be generated and can be evaluated by the application.

The ALLDAQ ADQ-412 offers a smart possibility to perform an user-specific adjustment. Depending on the application the user has the possibility to store specific adjustment data into an EEPROM additionally to the factory adjustment data (which can´t be overwritten).

By the ALLDAQ-Manager the user can select whether the factory or user adjustment should be activated when booting the computer.
