The AT-331 is a low power dual three-phase generator use as laboratory equipment to test three-phase protection relays and related equipment. Two independent three-phase channels can be generated to test your equipment under particular signal amplitudes, frequencies and angles. If you need more power, the two channels can be bridged to output more current (up to 1A).
Each output can be configured from our easy to use Graphical User Interface (GUI). In addition to that, the AT-331 has four digital I/O of which two can be used as trip input to shut down the corresponding channel.
