Product configuration
Basic application functions
Compact structure design, saves installation space
Clear terminal layout marking, easier to install
Wide voltage range design ensures the adaptability of products to power network fluctuations
Advanced independent duct design, adapt to a variety of complex, harsh site environment
Strong and Weak Electrical Isolation Design
Adopt srtong & week electrical isolation Design, to avoid magnetic field
interference and increase service lift.
Heat Dissipation Structure
Independent cooling duct optimization design, from the original right
angle optimization to rounded corner, reduce the thermal disk
accumulation, greatly increase the efficiency of heat dissipation.
After heat dissipation optimization, based on the previous structure to
reduce the side heat dissipation hole , the actual protection level can be
up to IP40, the protection performance is far ahead of similar products.
. Laminated Structure
BUS capacitor board and POWER motherboard laminated design. The
BUS capacitor board is arranged in an independent cooling air duct to
effectively dissipate heat.
The new design of laminated bus can reduce stray inductance, reduce
peak voltage and protect IGBT. At the same time, compact structure,
save installation space.
High Protection Structure Design
The inlet and outlet of the copper bar are closed with rubber rings,
which can effectively isolate the external dust and corrosive gas.
Epoxy partition is added to isolate the circuit installation area and form
an independent internal space to avoid damage to the circuit board
from the external environment and extend the service life
