The battery operated Constant Current Supply and Signal Conditioner Type AP9100 is intended for use with sensor/preamplifier combinations requiring a constant current excitation signal. Although optimised for use with pizo electric accelerometers having built in electronics, the AP9100 may just as well be used for powering and signal conditioning of microphone/preamplifier combinations requiring a constant current as power source. The unit is developed for portable use running on internal batteries. An external power supply can be used for long-term indoor use. For multi-channel applications the same instrument is available as a rack-module.
