Delta VFD-B is a speed control device and frequency inverter (VFD) produced by Delta Electronics. VFDs are used to adjust the frequency of power supplied to the motor in order to control the speed of an electric motor. The VFD-B series is designed to be used with standard three-phase induction motors and can be used in various industrial applications such as carriers, pumps, fans, and machine tools.

The Delta VFD-C2000 is a series of high-performance variable frequency drives (VFDs) produced by Delta Electronics. It is designed to be used with standard three-phase induction motors and is suitable for a wide range of industrial applications such as fans, pumps, carriers, machine tools, and material handling equipment.

The Delta VFD-E series is a series of sensorless vector AC micro drives produced by Delta Electronics. It is designed to be used for low power, fixed torque applications and is rated as IP20 to protect against solid objects larger than 12.5 mm. The VFD-E series has a modular design with flexible expansion cards and built-in PLC functionality, offering the ability to write and execute simple ladder logic programs.

The Delta VFD-EL series is a compact drive series with sensorless vector control. It supports the standard Modbus protocol through RS-485 and can share regenerative braking energy by connecting multiple VFD-EL drives in parallel. This prevents overvoltage and stabilizes the DC bus voltage. (Note: The 115V model does not support this function.)

The Delta VFD-F is a motor frequency drive designed specifically for controlling the speed of fans and pumps. The VFD-F is used to control the speed of the electric motor, allowing you to control the speed of the fan or pump. This allows for precise control of air or fluid flow, increasing efficiency, reducing energy consumption, and extending the life of the fan or pump.

Delta VFD-L is a frequency inverter produced by Delta Electronics. The "L" in the product name stands for "economy," and this drive model is designed for cost-sensitive applications. The VFD-L is an electronic device that controls the speed of an electric motor by adjusting the supply frequency. By controlling the speed of the motor, the VFD-L can also control the motor's torque and power, resulting in energy savings and increased system performance.

Delta VFD-M AC drives are a type of speed control device (frequency inverter) produced by Delta Electronics. They control the speed of an AC motor by adjusting the frequency of the electrical power supplied to the motor. The VFD-M series is designed to be used with three-phase induction motors and can be used in various industrial and commercial applications. Key features of the VFD-M series include high performance, energy savings, and ease of use.

The Delta VFD-S is a special brand and model of speed control device produced by Delta Electronics. It is designed to be used with single-phase input and three-phase AC motors, and can be used in various applications such as HVAC, pumps, fans, and carriers. The VFD-S features a user-friendly interface, high performance, and energy savings.
