The Allen Bradley 20DD2P1A3NYYACASE is classified as a variable-frequency AC drive. Designed to handle a supply voltage of 480 VAC, this unit efficiently operates using a three-phase power supply. The rectifier utilizes a six-pulse diode front-end configuration, optimizing performance for various motor control tasks.
It provides a maximum continuous output current of 2.1 A. The drive is suitable for normal-duty applications with a power capacity of 1 HP (0.75 kW) and can manage workloads of 0.75 HP (0.55 kW) during heavy-duty cycles. This specific model, called Frame 1, aids in its compact installation.
An IP20 enclosure rating adds a layer of protection appropriate for less harsh environments, while the conformal coating applied safeguards the internal components from moisture and dust. User interaction is facilitated through an LCD incorporating a full numeric keypad, allowing straightforward programming and operation.
An integrated brake IGBT and an on-board resistor module are installed for braking capabilities, ensuring safe and reliable stopping performance. Additionally, the system is equipped with a ControlNet DPI coaxial communication module, supporting connectivity in automation networks. Control is achieved via a Phase II vector control scheme, enhancing precision in motor operation. The drive incorporates a safe-off function for emergencies, guaranteeing safe isolation during critical situations.
