Basic Overvie
Definition and function: The frequency conversion vfd cabinet is an electrical control cabinet that integrates frequency converters, circuit breakers, contactors, relays, PLC and other components. It is mainly used to adjust the speed and power of the motor.
Composition structure: Frequency conversion cabinet usually includes input power supply, frequency converter, output circuit, protection device (such as overload protection, short circuit protection) and control system.
Advantages And Characteristics
Power conversion: The VFD control cabinet converts fixed frequency AC power into adjustable frequency AC power to meet the needs of different load conditions. This process is realized through the rectification, filtering, inverter and other links inside the frequency converter.
Motor control: By changing the frequency of the output power supply, the frequency conversion cabinet can control the speed and torque of the motor, thereby achieving precise control of the equipment.

Split Phase VS Single Phase:
Split - phase and single - phase are different. Single - phase power is a basic single - circuit AC power supply, common for small - power home appliances, consisting of one live wire and one neutral wire. Split - phase, essentially a type of single - phase, derives two voltage branches with a 180° phase difference from a single - phase source. For example, the common 240V/120V supply can meet different power demands and is often used in North American households to power high - power appliances like electric stoves.
