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.
