4112B, Line Powered Current Source Power Unit

The Dytran model 4112B is a line-operated constant current power unit designed to power IEPE sensors. This power unit separates the sensor’s dynamic signal from its DC bias voltage and amplifies the sensor signal by selectable factors of X1, X10 or X100.

Units supply a fixed 4 mA of constant current power to the IEPE sensor. If more current is required for a specific application such as when driving long cables, it is possibly to modify this unit to provide up to 20 mA of sensor drive current. Consult the factory for details.

Model 4112B may be used as a stand-alone “desktop” unit or may be rack mounted in an available 19-inch wide by 5.25-inch high rack adaptor. The narrow width (only 1.65 inches) allows up to 10 model 4112B’s to be installed in the Dytran model 4200 rack adaptor.

Model 4112B is normally line-operated from 115VAC mains, 50-60 Hz. A 230VAC version, Model E4112B, is also available for use in countries where the normal line voltage is 230VAC.
