Digital Switch Power Amplifier Overview:

1. Users can check the working status of each module and system at any time. If a power module fails, it can be removed manually.

2. With power factor compensation device, the power factor of the whole power amplifier is up to 92%, so that the power grid capacity can be fully utilized.

3. Using sinusoidal frequency double pulse width modulation technology, the power amplifier has a high signal-to-noise ratio.

4. Using the working principle of switching power supply, the conversion efficiency is high, and the conversion efficiency of the power module can reach 92%. The entire power amplifier system is completely forced air-cooled.

5. Using electronic automatic current-sharing technology, the parallel connection of each module is almost the same, and the parallel unbalanced current sharing ratio is ≤2%.

6. The power device adopts imported field effect modules (other domestic manufacturers generally use field effect single-tube). The protection circuit is reduced, the reliability is improved, the current capacity is large, and the maximum output of a single power module box is 25 kVA.

7. The power module box is small in size, with 5kVA, 10kVA, 15kVA, 20kVA, etc., which can be selected according to the user's actual situation.

8. Complete protection function, the entire power amplifier has 18 protection functions

Vertical Expansion Table:

In the actual vibration test, the tested product is often larger than the electric table top. At this time, it is necessary to expand the original table top. A common method is to install an auxiliary table. Some tested products require special installations. This requires a custom fixture to meet this installation. Both of the above conditions must meet certain technical specifications, such as working frequency, table weight, table acceleration, amplitude uniformity and laterality, etc. Therefore, there are strict requirements for such tables or fixtures. The TB expansion table and special fixtures have been carefully calculated and carefully designed to ensure the user obtains the optimal performance from the structure, materials, and manufacturing processes.

Horizontal extension slide:

It has a high tipping moment and lateral limitation. At the same time to maintain the steering oil film damping characteristics. The water smoothing platform is composed of a skateboard, a connector, a natural granite plate, and a horizontal slide base.

The high-pressure oil becomes a low-pressure oil through the damper, forming a layer of oil film between the bottom surface of the slide table and the granite plate. The oil film mainly plays the role of lubrication and reduces the friction generated when the sliding table mesa moves on the granite plate. Make the horizontal slide table free to move on the granite slab. The high-pressure oil source and the horizontal slide are connected together by the high-pressure oil pipe, so that the horizontal slide system has a simple structure, convenient operation and maintenance, and reliable operation.
