0.75KW To 110KW Frequency Inverter Three Phase Output VFD VSD
Description of variable frequency drive
Independent cooling air duct design
Effectively prevent external pollution from entering the product,
causing corrosion and short circuit of PCB, components, etc.
To improve the stability of the product, the cooling fan with long
life and large air volume is selected to effectively reduce the
temperature rise of the inverter and ensure the reliable and stable
operation of the product.
Strict component selection
Select first-class suppliers in the industry for capacitors, fans,
electronic components, PCB boards, etc. to ensure the health and
stability of the product life cycle.
Unique conformal paint
The three-proof paint adopts a special process to increase the
environmental resistance of the circuit board and comprehensively
improve the protection ability of the veneer. Special industries
can be customized according to the site environment
Brand new design
A new generation of IGBT module technology is selected, with high
junction temperature, high power density, smaller machine size, and
saving installation space.
EMC/EMI design is strict
After a variety of equipment tests, the product is guaranteed to
run stably in various environments with minimal interference to the
entire environment.
Wide voltage design
In line with international standards, it meets the needs of
380-480V three-phase power grids including Europe, North America,
India, etc.
