Delta VFD-S Manuals
What is Delta VFD-S ac drive?
The Delta VFD-S is a specific brand and model of VFD that is manufactured by Delta Electronics. It is designed for use with single-phase and three-phase AC motors, and it can be used for a variety of applications such as HVAC, pumps, fans, and conveyors. Features of the VFD-S include a user-friendly interface, high performance, and energy savings.
The models listed in the first section (S1) are suitable for motors with power ratings between 0.25 horsepower (0.2 kW) and 2 horsepower (1.5 kW), and the models listed in the second section (S2) are suitable for motors with power ratings between 1 horsepower (0.75 kW) and 5 horsepower (3.7 kW).
The different models have different features and are designed for different types of applications. The letters at the end of each model number indicate the version of the drive, such as A, B, E, and U. For example, VFD007S21A is a 7amp model, VFD007S21E is a 7amp model with built-in PLC function, VFD015S23D is a 15amp model with built-in braking unit.
It is important to note that these are just some examples of the VFD-S AC drive models that Delta Electronics produces and there are other models and variations available with different specifications and features. It is recommended to check the product manual and consult with the manufacturer or a technical expert to ensure that you select the correct model for your specific application.
