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.
