Introduction
PRO PS12A power unit is a 19 inch wide by 1 3/4 high rack mountable, line powered current
source power units designed to power 12 channels of regulated current style sensors and in-
line charge amplifiers.
NOTE: SENSORS may refer to accelerometers, pressure sensors, hammers and force
transducers, etc. The words SENSOR and TRANSDUCER are used interchangeably in this guide.
PRO model PS12A can support up to 12 channels, simultaneously. The sensor signal, riding atop
an approximate +12 volt bias level is decoupled from this DC bias by use of a 10µF coupling
capacitor for each channel.
The PS12A has a sturdy, powder-coated aluminum case that fits standard 19” racks. The front
panel has a convenient switchable output BNC to monitor a single channel at a time. The switch
also selects the channel of the easy to read 7 segment bias display. All channels have a red-
green LED sensor condition indicator light.
On the Back Panel, there are 12 sensor BNC’s, as well as 12 output BNC’s. In addition there are
terminal block inputs that can be used for both the sensors and outputs, in lieu of BNC jacks.
