Introduction of variable frequency drive
With the continuous development of industrial automation, inverter
as a key device to control motor speed has
become an indispensable device in many industrial fields. Our ST310
inverter, which adopts V/F control mode,
is suitable for three-phase asynchronous motors and can operate at
220V, 380V and 480V. Moreover, the ST310
inverter offers extreme flexibility and reliability for various
industrial equipment applications in the power range of
0.75KW-450KW. The control mode of ST310 inverter adopts V/F control
method, which can adjust the motor speed
as needed, thus achieving higher efficiency and more accurate
control. In addition, the ST310 inverter has advanced
protection functions, including overload, overvoltage, undervoltage
and overheating, which can ensure the reliability and
safety of the equipment.Our ST310 inverters are widely used in
various industrial equipment fields, such as industrial
production lines, ventilation systems, pumps and fans. Our
inverters have been proven to improve equipment performance
and energy efficiency in practical applications and have received
positive feedback from many customers.
Structural design of variable frequency drive
Shell material (full series)
ABS+PC (Polycarbonate and acrylonitrile-butadiene-styrene copolymer
and mixture, is a thermoplastic
plastic made from Polycarbonate and acrylonitrile-butadiene-styrene
copolymer (ABS), combining the
excellent properties of both materials)
Advantages:
High-temperature resistance, flame retardant (thermal deformation
temperature 80-125°)
High flexibility and impact resistance
High UV resistance and long service life
Thin, samll and exquisite volume (All series)
Advantages: save space and save installation costs.
Reasons:
① Internal design: there is an independent circuit designer, using
4-layer PCB board, electronic components,
integrated circuits, and using the most reasonable design, so that
the PCBA has no flying wires (jumpers) and
is small in size.
② Structural design: There are independent structural development
engineers, which do not use male molds,
and are completely independent and independent research and
development combined with heat dissipation,
easy disassembly and assembly, and aesthetics.
