The PCB Piezotronics I.C.P Model 482A Power Supply is a single-channel, line-operated signal conditioner for ICP transducer systems. This unit provides constant current excitation to the built-in transducer amplifier and decouples the signal from the DC bias voltage.

The unit also contains provision for fault monitoring the channel, as well as provision for externally varying the constant current output over a 2 to 20 mA range. This model is factory set at 4 mA.
