IEPE Power Supply
$499
The ASC-1401-SAL Integrated Electronics Piezo-Electric (IEPE) Power Supply provides an excitation for piezoelectric sensors, or other Constant Current Power (CCP) devices / sensors that require a constant current excitation. This portable, rechargeable battery powered device’s flat frequency response provides true, source-accurate broadband data. Both passive and active coupling versions are available. Active versions with filtering and amplification condition the signal to drive data acquisition systems. The excitation current is adjustable from 1 mA to 15 mA: in 1 mA steps.
