Description

PAS preamplifier has the functions of 4 filters and 3 gains, and can be connected to differential sensors.

It is available in both phantom and adapter power supply, and it is compatible with most common sensors

and acoustic emission acquisition boards on the market.

Note:

1. The power supply should be a good match with the output impedance, otherwise it will lead to the

gain of the preamplifier to deviate from the nominal gain value, resulting in signal amplitude deviation.

2. If AE board from other manufacturers are selected, a PPS preamplifier power supply is required.

3. Wiring must be correct. The following three wrong operations may lead to damage to the preamplifier:

a. The input voltage is 25% higher than the power supply requirement.

b. Connect the power supply to the signal input connector.

c. The positive and negative terminals of the powersupply are inversely connected
