Low Voltage Frequency Conversion Cabinet
product description
The frequency conversion cabinet is mainly used to adjust the
operating frequency of the equipment, reduce energy loss, start the
equipment smoothly, and reduce the damage to the motor caused by
the large current generated when the equipment is started directly.
At the same time, it comes with analog input, PID control, pump
switching control, communication function, macro function,
multi-speed and other functions. Frequency conversion cabinet has
become the currently popular power drag method due to its good
starting performance, speed regulation performance and
energy-saving effect.
typical application
It can be widely used in various low-voltage motor equipment such
as metallurgy, chemical industry, petroleum, water supply, mining,
building materials, motor industry, pumps, constant pressure water
supply, fans, compressors, rolling mills, injection molding
machines, belt conveyors, etc.
Usage environment
Frequency conversion cabinets should not be installed in places
subject to vibration. The vibration acceleration is usually limited
to below 0.3~0.G:
The ambient temperature of the installation site cannot exceed
(-10~40C):
·Environmental humidity ≤95%RH, no water condensation, avoid direct
exposure of the inverter to the sun;
The frequency conversion cabinet should be installed indoors, away
from direct sunlight, dust, corrosive, flammable gases, oil mist,
water vapor, dripping water or salt.
Control type
Liquid level control: The control cabinet is equipped with a
high-performance Key float switch, which automatically controls the
start and stop of the water supply and drainage pump according to
the high and low changes in the liquid level.
Pressure control: An external electric contact pressure gauge or
pressure controller can automatically turn on and off the pump
according to changes in pipe network pressure. This type is widely
used in domestic water supply and firefighting booster systems.
Temperature control: Connect an external temperature controller to
turn on or off the pump according to the set temperature range. It
is used in situations where temperature control is required such as
constant temperature and heat exchange systems.
Time control: The chassis panel is equipped with time setting
buttons and a display. The user can control the opening and closing
of the water pump according to timing needs. It is suitable for the
control of various timing or regular intermittent working methods.
