Description

Technical Field

[0001] The utility model belongs to the technical field of sensor power supplies, and particularly relates to a combined power supply. Background Technique

[0002] IEPE refers to an acceleration sensor with a built-in charge amplifier or voltage amplifier. IEPE is the abbreviation of piezoelectric integrated circuit. Since the electric charge generated by the acceleration sensor is very small, the electrical signal generated by the sensor is easily affected by noise interference, and sensitive electronic devices are required to amplify and condition the signal. Sensitive electronic devices are integrated in IEPE to make it as close as possible to the sensor to ensure better noise resistance and easier packaging.

[0003] Existing IEPE sensors usually use a constant current voltage source as the power supply for the sensor, which is also a necessary configuration for IEPE sensors. At present, there are generally two forms of the constant current voltage source:

[0004] 1. The constant current voltage source is integrated with the data acquisition system, that is, the data acquisition system has a built-in constant current voltage source;

[0005] 2. An independent constant current voltage source, which is used as a separate unit of the test system.

[0006] However, the function of the independent constant current voltage source product is single, with only single input and single output functions. In addition, in addition to the voltage output type, there are also charge output type products for acceleration sensors. When in use, a constant current voltage source and a charge amplifier need to be used separately, resulting in an increase in the number of devices used and an increase in cost, and it is not flexible.

[0007] Therefore, the utility model provides a combined power supply to solve the problems existing in the above background technique. Content of the Utility Model

[0008] Aiming at the problems raised in the above background technique, the purpose of the utility model is to provide a combined power supply, enabling users to flexibly combine multiple input and output functions through one device.
