The custom variable frequency cabinets utilize PLC programmable logic controllers to control electrical components, accomplishing motor equipment control and communication functions. The converter is a power control device for AC motors that regulates power by altering the frequency of the motor's working power supply. How do you select the right variable frequency cabinet? Here are its features! Take a look!
How to Select the Right Variable Frequency Cabinet?
1. The power capacity should exceed the inverter's rated power. Select the corresponding voltage level based on the rated voltage of the power source and motor. The working voltage is 380-460 volts, with a frequency of 50/60 Hz, and a three-phase power supply. Please note that the allowable fluctuation range for the power source voltage is +10% to 15%.
2. Three-phase asynchronous electric voltage, capacity selection) Type selection: Use three-phase asynchronous motors; single-phase motors are not applicable. Voltage selection based on the inverter voltage, 200-230VAC/380-460VAC. Capacity selection according to capacity. Do not use a rotor for driving unless it is a three-phase asynchronous motor. The converter's capacity should be greater than the motor's capacity, with its output current exceeding the motor's rated current. The converter's operating signal is used for motor startup.
3. The converter installation environment should be installed within a cabinet and attention should be paid to heat dissipation. The environmental temperature is -10 to +50°C, humidity less than 90%, and free of special gases.
Custom Variable Frequency Cabinet Features Include:
1. Start/Stop Control Function: Huapu拓 Electric's PLC variable frequency drive control cabinet features a human-machine interface, with start and stop buttons for variable frequency, used to control the operation of the variable frequency unit or to install buttons on the panel.
2. Communication Function: The PLC variable-frequency inverter control cabinet is connected to the host, enabling remote control and remote measurement over long distances.
3. Intuitive Data Monitoring: Voltmeters, ammeters, frequency meters, various indicator lights, alarm devices, and more, allowing for real-time detection and control of various operational states. Upon customer request, a human-machine interface can be set up. The data can also be visually observed through the human-machine interface.
4. Power Switching and Protection Function: HuapuTuo's electrical PLC variable frequency inverter control cabinet is installed with circuit breakers connected to the incoming power supply. It not only completes the connection and disconnection of the circuit but also protects against overloading and short-circuiting of the circuit and inverter. It automatically shuts off power during maintenance.
