VFD Control Panel Manufacturer

Variable Frequency Control Cabinets are a powerhouse of efficiency and performance. With an inverter as the core, they precisely adjust motor speeds by altering power supply frequencies. This results in remarkable energy savings, especially under light or no - load, with savings typically between 20% - 45%. By maintaining a constant speed across varying loads, production efficiency gets a significant boost. They also reduce wear on motors and equipment, cutting maintenance costs. The addition of reactors helps with anti - interference and filtering. Ideal for industries seeking to optimize operations, these cabinets are a top - tier choice for power control

The inverter cabinet with reactor is mainly composed of inverter, AC input reactor, DC reactor (optional), output reactor (optional) and peripheral control, protection, display and other electrical components and cabinets. Among them, the inverter, as the core component, controls the power control equipment of the AC motor by changing the frequency of the motor working power supply.

During installation, the short-circuit copper busbar between the main circuit terminals P(+) of the inverter needs to be removed, and then the DC reactor is connected between P(+). In addition, according to the system working conditions, EMI filters, brake units, brake resistors, contactors, intermediate relays, thermal relays, programmable controllers (PLCs), programmable operation terminals (GOTs), electric meters, cooling fans and other components can also be installed in the frequency conversion cabinet.

Advantages And Characteristics

Under light or no-load conditions, the speed of the motor can be reduced, thereby significantly reducing energy consumption. According to statistics, the energy-saving rate of using a variable frequency control cabinet is generally around 20% -45%.

The variable frequency control cabinet can maintain a constant speed under different load conditions, thereby improving production efficiency.

The variable frequency control cabinet can reduce the wear and tear of motors and mechanical equipment, lower maintenance frequency and costs by controlling the running time and current fluctuations.

The accuracy of variable frequency control motor speed is improved, so it can keep the system pressure change of the pipeline network within the range of 3pisg, that is, within the range of 0.2bar, effectively improving the quality of the working conditions.

Product Details

The addition of an incoming line reactor is used for anti-interference, to prevent the inverter inside the inverter cabinet from interfering with other equipment, while the outgoing line reactor is used for filtering. The general frequency conversion carrier frequency is 2~10 khz, which can make the output waveform smoother.

The incoming line reactor is used to prevent the inverter from generating harmonic interference to the power grid and surrounding equipment. Since the inverter output is a high-frequency rectangular wave, the AC waveform output by the inverter should be optimized. In addition, the grounding capacitance on the inverter outlet side can be prevented, and the cable length from the inverter to the motor side can be extended.
