Features and Advantages
| No. | Index | Advantages and Features |
| 1 | Dynamic guide | The suspension moving coil system is composed of U-shaped springs and rollers. It is the latest design of LDS in the United Kingdom. It has a high partial load moment, and at the same time, the lateral vibration ratio of the moving coil is small and the waveform distortion is small. It meets international level requirements. (Figure 1) |
| 2 | Key components | Power devices, moving coils, and excitation wires are all imported. (Figure 7) |
| 3 | Power module | It adopts German Infineon IGBT power devices, and the maximum output power of a single power module box is 60KVA, with simple structure, comprehensive protection and high reliability |
| 4 | True high voltage amplifier | The voltage of a single power module is 320V, and the output form of high voltage and low current reduces the power loss in the transmission process and realizes effective and reasonable impedance matching. |
| 5 | Logic module for power amplifiers | The logic module adopts PLC control, touch screen display function (the touch screen adopts French Schneider products); it can display various data of the system in detail (real RMS value of power amplifier output, additional data display), operating status and fault judgment. (Figure 2) |
| 6 | Power amplifier CE certification |
The power amplifier series all have CE certification. The high-power power amplifier is the only product in China that meets the relevant standards of CE/EMC electromagnetic compatibility, leading in China. The power amplifier has passed the second demonstration of TUV Rheinland (attached certificate)CE/LVD Low Voltage Directive (Safety); CE/EMC Electromagnetic Compatibility Directive Electromagnetic compatibility is divided into two parts:The elimination of grid conduction interference adopts a special second-order power supply and filter. (Figure 6) Radiation interference adopts a fully shielded cabinet design. It has an anti-electromagnetic radiation shielding layer to protect the human body from radiation damage, leading in China. (Physical pictures of treatment measures that meet relevant standards, Figure 3) EMC electromagnetic compatibility is a mandatory specification in Europe and the United States. It has also been paid more and more attention in China. The power amplifiers produced by domestic counterparts seriously exceed the EMC standard, and the high-power power amplifiers seriously affect the use of other instruments in the laboratory through conduction emission and radiation during operation. |
| 7 | Anti-electromagnetic radiation shielding layer | The power amplifier is equipped with an anti-electromagnetic radiation shielding layer required by CE to protect the human body from radiation damage. (Figure 3) |
| 8 | Power amplifier cooling | Power amplifier cooling absorbs the experience of British LDS, American UD and other companies. It adopts bottom air intake and top exhaust system to ensure high heat dissipation and ensure good heat dissipation in the box when the power amplifier is running for a long time. (Figure 4) |
| 9 | Power amplifier protection function is complete |
The entire power amplifier has: grid overvoltage, grid undervoltage, grid phase loss, logic fault, power module protection, power module temperature, output overcurrent, output overvoltage, drive power, platform displacement, platform temperature, external interlocking, etc. protective functions. When any fault occurs, the output will be closed, and the sound and light will alarm at the same time. In addition to the above protection, the true effective value sampling chip is introduced to make the sinusoidal Serve and random pass the true effective value (RMS value) control, which has the characteristics of safety and reliability. The technology is mature and there is no such technology in the domestic industry, leading in China. |
| 10 | Remote control | Adopt RS485 communication interface, optional remote control up to 1000 meters, with the same power amplifier protection function as the power amplifier logic control unit. |

Original Position Central Servo (OPCS) |
The moving coil of the electric vibrating table can be automatically centered, mainly through the non-contact sensor to monitor the center position of the moving coil of the electric vibrating table, and by automatically adjusting the air volume of the supporting air spring of the moving coil of the electric vibrating table to maintain the center of the table top of the electric vibrating table, so that the system can automatically center the moving coil in the static and dynamic state. The table is equipped with an emergency switch protection function to protect and cut off the output of the power amplifier, leading in China. (Figure 4) |
| 12 | Random Test Dynamic Range | The random test dynamic range up to 42dB ensures strong anti-interference ability and undistorted waveform when testing low-frequency small signal signals. (The international level is 50dB, and the domestic level is generally 39-40dB) (Figure 8) |
