China wholesale Vibration Test Machine - High frequency vibration table – Hongjin Detail:
Lab Equipment Electrodynamic Vibration Mechanical Shaker High Frequency Vibration Tester XYZ axis Vibration test machine
Digital switching power amplifier
The system uses a digital power amplifier with sinusoidal pulse width modulation. The working principle is: using the high-frequency switching capability of the IGBT FET, the low-voltage signal input by the controller is amplified by the digital circuit and restored to the original signal, and then output to the moving coil of the vibrating table to promote the electric vibration. Taiwan movement.
The main components of the intelligent high voltage power amplifier are: front control, power amplifier module, protection circuit, power supply part and electric cabinet. The system adopts high voltage and small current output form, which reduces the power loss during transmission and achieves effective and reasonable impedance matching.
