Product Description

Product Description

 

The MPA series power amplifier is a digital power amplifier using sinusoidal pulse width modulation technology. Its working principle is: using the high-frequency switching capability of MOSFET field effect tubes, the low-voltage signal input by the controller is amplified and restored to the original signal through the digital circuit, and then output to the dynamic circuit of the electric vibration table to drive the tabletop of the electric vibration table to move. The main components of the digital power amplifier are: logic module box, power amplifier module box, protection circuit, excitation power supply part and electric cabinet. The output range of the MPA power amplifier is 1kVA~1000kVA. The system technical indicators are fully applicable to existing or new air-cooled or water-cooled electric vibration tables. It can be used to replace the power amplifiers of the same model from other manufacturers. The MPA series power amplifier is a wide-band digital switching power amplifier designed with new technology, mainly composed of logic module, power module, excitation power supply module, etc. The power devices of the MPA series power amplifier are all supplied by well-known American companies, and the quality is guaranteed. The MPA series power amplifier products have passed the European "TUV Rheinland" CE certification.
Product features:
Easy maintenance: Interchangeable power module box, compact design, space saving, easy maintenance, and quick maintenance.
High power factor: With the power factor compensation device, the power factor of the power amplifier can reach 95%, so that the power grid capacity can be fully utilized.
High performance index: Adopting sine frequency multiplication pulse width modulation technology, high switching frequency, high signal-to-noise ratio, and low total harmonic waveform distortion.
High conversion efficiency (greater than 95%), high modulation conversion frequency.
LCD display: The logic module adopts CPU microcomputer chip processor and LCD display function; it can display various system data in detail (the real RMS value of the power amplifier output, additional data display) and operating status and fault judgment, with a friendly interface and easy operation.
Data recording: The logic module can record the operating time, fault status, and maximum output.
Simple setting: More humanized function setting, interlocking setting, users can set various protection functions according to requirements.
Complete protection functions: The power amplifier is equipped with protection circuits such as grid overvoltage, grid undervoltage, grid phase loss, logic fault, power module direct pass, power module temperature, output overcurrent, output overvoltage, drive power supply, table displacement, table temperature, external interlocking, etc. When any fault occurs, the output and the power amplifier are turned off to protect the system and sound and light alarms are sounded.
Adopting current equalization technology: electronic automatic current equalization technology, parallel current equalization imbalance ≤1%.
Good safety performance: multiple EMI suppression design, power input is equipped with EMI filter; power amplifier cabinet is fully shielded, electromagnetic interference is low, so that the product meets the electromagnetic compatibility requirements of CE standards.
Advanced technology: absorbing advanced technologies from Japan, Europe and the United States, and combining its own high-frequency switching power supply control technology advantages, after secondary development, the technology is more advanced, the performance is more reliable, and it is fully modularized. The products have been fully exported to the European and American markets and have received good reviews.
Remote control: It has a remote control panel control function with superior performance (optional).
Convenient update: MPA series power amplifiers can be used to replace power amplifiers of the same model from other manufacturers.
