ABB ACS880-104-0900A-3

Of course. Here is the English translation of the introduction to the **ABB ACS880-104-0900A-3** frequency converter.
Okay, let's delve into a detailed introduction of the **ABB ACS880-104-0900A-3** frequency converter.
First and foremost, it is important to clarify that this is a **high-power, multi-drive** inverter module, belonging to the high-end industrial application products within ABB's ACS880 series. It is significantly different from the wall-mounted or compact book-type modules introduced earlier, as it is specifically designed for heavy-duty industrial environments.
We can break down this model number to understand its key information:
*   **ACS880**: **Product Series**
*   **104**: **Product Type / Structure Specification**
*   **0900A**: **Rated Output Current**
*   **3**: **Voltage Level**
### 1. Product Series: ACS880
The ACS880 is a **fully compatible, modularly designed standard AC drive series** launched by ABB. It is the core of ABB's drive product line, renowned for its flexibility, powerful features, and excellent performance.
**Core features of the ACS880 series include:**
*   **Universal Platform:** Unified firmware and user interface simplify selection, design, commissioning, and maintenance.
*   **Modular Design:** Supports various optional functional modules, such as I/O extension cards, fieldbus adapters, and encoder interface cards.
*   **High-Performance Control:** Supports **DTC (Direct Torque Control)** technology, providing outstanding dynamic speed and control accuracy.
*   **Comprehensive Safety Functions:** Features a standard integrated **Safe Torque Off (STO)** function.
*   **Powerful Communication Capabilities:** Supports almost all mainstream industrial networks via adapter modules.
### 2. Model Code: ACS880-104-0900A-3
Now, let's analyze the subsequent codes one by one:
*   **104**:
    *   This refers to the drive's **product type and structure specification**. The code **`104`** indicates that this drive is a **multi-drive module** within the ACS880 series.
    *   This type of module is typically used in complex systems requiring multiple drive units and can operate as a slave module in a common DC bus system. It requires an external control unit (such as the ACS880-U1/U2/U3 control module) for operation and monitoring.
*   **0900A**:
    *   This part indicates the drive's **rated output current**. This is the most critical performance parameter.
    *   `0900A` means the unit has a **rated output current of 900 Amps**. This is a very high current value, indicating this is a high-power drive.
*   **3**:
    *   This number represents the **input voltage level**.
    *   `3` corresponds to **690V** three-phase AC power (-3 denotes the 690V class, -7 denotes the 400V class). This means the drive is designed for medium-voltage industrial power grids like **660V/690V**.
### 3. Technical Parameter Summary
