RPA-05 is intended for use with acoustic-emission system Ranis-11, the supply voltage 28 V. The gain is selected using jumper on the board.
Amplifier is mounted inside a sealed aluminum housing that provides protection against dust and moisture according to IP65.
At the bottom of the housing the strong magnet is mounted over electrical insulator. The isolator is necessary to isolate the circuit ground from the body of the object under test. Magnet provides a clamping force up to 14kg on steel magnetic surfaces.
