PPS Preamplifier Power Supply& Signal Separator
Model：
PPS
Description：
PPS Preamplifier Power Supply Signal Separator is used for giving power supply to preamplifier. When you choose a non professional AE acquisition system or general DAQ made by other manufacturers, it is necessary to connect PPS and power adapter to supply power to preamp.
Features：
Two types of PPS available

Preamplifier Power Supply& Signal Separator （PPS)
Description
PPS is the preamplifier power supply and signal separator. When you choose the data acquisition board that can not supply power to the preamplifier and also there is no power adaptor can be connected to the preamplifier, it is necessary to connect PPS and power adapter to supply power to preamplifier, to ensure normal usage of the preamplifier and to separate the signals.
For example, most non AE acquisition systems don’t supply voltage power to the analog inputs, such as oscilloscopes, or NI DAQ. So if you are using these DAQ or instruments and also your sensors are with built-in preamp or PAV, it is necessary to add the PPS before your DAQ. The connections are demonstrated below in the diagram.
There are two types of PPS available, PPS50 and PPS2000 respectively. The difference is the output impedance of the PPS. Choose the PPS type according to the input impedance of the DAQ or oscilloscopes. If input impedance of the end instrument is low, choose PPS50. If the input impedance is very high, choose PPS2000.
