ABB ACS880-31 Wall-Mounted Ultra-Low Harmonic Drive

# **ABB ACS880-31 Wall-Mounted Ultra-Low Harmonic Drive — Clean Power, High Efficiency, Intelligent Control**
In modern industrial environments, power quality has become a critical factor influencing production efficiency, equipment lifespan, and overall system reliability. As variable-speed drives become more widespread, harmonic distortion has emerged as a major challenge, affecting transformers, switchgear, sensitive automation equipment, and even the stability of entire electrical networks.
To address these growing concerns, ABB developed the **ACS880-31 series wall-mounted ultra-low harmonic drives**, integrating advanced Active Front End (AFE) technology and compact mechanical design. This product delivers superior harmonic mitigation, outstanding motor control performance, and simplified installation, making it one of the most trusted solutions for industries seeking clean and efficient electrical power.
## **1. Industry-Leading Ultra-Low Harmonic Performance**
The most remarkable strength of the ACS880-31 is its **built-in active front end rectifier combined with an optimized harmonic filter**. Unlike traditional solutions that rely on DC chokes or external harmonic filters, the ACS880-31 can reduce the Total Harmonic Current Distortion (THDi) to **as low as 3%–5%**, far below the requirements of IEEE 519.
This brings multiple advantages:
* **Significantly reduced harmonic pollution**
  Protects upstream transformers, busbars, motors, and sensitive automation equipment from harmonic-related damage.
* **Improved power system stability**
  Ideal for weak grids, long cable distances, and industries with strict power quality demands.
* **Lower investment and smaller footprint**
  Eliminates the need for bulky external harmonic mitigation equipment.
These features make the ACS880-31 a preferred solution for data centers, semiconductor manufacturing, precision production lines, pharmaceutical plants, and other mission-critical facilities.
## **2. Compact Wall-Mounted Design for Flexible Installation**
The ACS880-31 adopts a **fully optimized wall-mounted structure**, enabling fast deployment even in space-constrained environments. It can be installed on:
* Control room walls
* Machine frame structures
* Cabinet side panels
* Distributed drive stations near production lines
By saving floor space and reducing installation complexity, the wall-mounted model is especially valuable for retrofit projects or distributed motor control systems.
The internal airflow path and cooling design have been engineered for high power density, ensuring stable performance even in compact or semi-enclosed areas.
## **3. Outstanding Motor Control Powered by ABB DTC**
As part of ABB’s flagship **ACS880 all-compatible drive family**, the ACS880-31 is equipped with the renowned **Direct Torque Control (DTC)** technology. DTC offers:
* High dynamic response
* Accurate torque control even at zero speed
* Fast load adaptation
* Compatibility with multiple motor types
The drive supports asynchronous induction motors, permanent magnet motors, synchronous reluctance motors, and high-efficiency IE4/IE5 motors. This allows users to upgrade their systems without replacing existing motors, significantly reducing retrofit costs.
To integrate seamlessly with industrial automation systems, the drive supports multiple fieldbus protocols:
* Modbus
* Profibus-DP
* Profinet
* EtherNet/IP
* CANopen
* DeviceNet
This ensures easy connection to PLC systems from ABB, Siemens, Schneider Electric, Rockwell, and other major automation brands.
## **4. Intelligent Features and Enhanced Safety**
The ACS880-31 incorporates numerous smart functions designed to simplify commissioning, reduce downtime, and enhance operational safety.
### **● Built-in Condition Monitoring**
The drive continuously monitors:
* Input voltage and current quality
* Harmonic distortion levels
* Internal temperature
* Component life expectancy
* Load patterns and operational history
Diagnostics and alarms are clearly displayed on the control panel or accessed through ABB’s PC tool, allowing proactive maintenance and fast troubleshooting.
### **● Integrated Safety Functions (up to SIL3)**
Safety features include:
* STO (Safe Torque Off)
* SBC (Safe Brake Control)
These functions improve system safety while eliminating the need for complex external wiring.
### **● Modular and Service-Friendly Design**
The modular structure enables:
* Easy installation and wiring
* Fast replacement of power modules
* Shortened maintenance time
* Reduced lifecycle cost
The design reflects ABB’s philosophy of maximizing uptime and minimizing operational complexity.
## **5. Higher Efficiency and Reduced Energy Consumption**
Leveraging AFE technology, the ACS880-31 provides:
* **Unity or near-unity power factor (0.98–1.0)**
* **Reduced reactive power consumption**
* **Efficient regeneration capability** (where applicable)
* **Lower electrical losses**
These advantages result in significant energy savings throughout the life cycle of the equipment. For large facilities consuming substantial electrical energy—such as HVAC systems, pumping stations, and manufacturing processes—the drive enables noticeable cost reductions and supports corporate carbon-reduction initiatives.
## **6. Wide Range of Industrial Applications**
Due to its clean power performance and excellent control precision, the ACS880-31 is widely used across:
* Manufacturing and assembly lines
* HVAC and building services
* Pumping and ventilation systems
* Food & beverage processing
* Textile and paper industries
* Chemical and pharmaceutical sectors
* Electronics and semiconductor production
* Data center cooling and infrastructure
Its ability to operate reliably even under challenging power conditions makes it a powerful asset for industries striving for continuous, stable operations.
