The used Altivar 71 160 kW inverter from Schneider Electric is an excellent solution for managing the speed of electric motors. This model, Altivar 71 , is known for its high performance, capable of handling powers up to 630 kW, and offers advanced control for both synchronous and asynchronous motors.
Visually, the Altivar 71 has a robust design, with a front user interface that includes a digital display for adjusting and monitoring settings. The structure is compact, designed for panel installation, and includes numerous safety and control components, such as integrated heat sinks to ensure maximum operational efficiency. Schneider Electric control panel , supplied with this used version, is an added value, guaranteeing perfect functioning and conformity of the system.
Altivar 71 model supports three-phase motors, and is designed for powers from 0.37 kW up to a maximum of 630 kW. The 160 kW inverter is particularly suitable for heavy industrial applications, such as pumps, fans and conveyors. Power supply voltages range from 200 to 690 V, covering a broad spectrum of global industrial applications. Its measurements allow easy integration into industrial electrical panels, with a small footprint despite the power managed.
The operation of the Altivar 71 is very intuitive: thanks to the control panel, the operator can easily set parameters such as the working frequency, the current and voltage thresholds, and the starting and stopping speeds. Continuous speed regulation offers precise control, especially useful in applications requiring dynamic changes in speed or load.
This inverter supports various accessories, such as communication modules for integration into automation systems and remote monitoring via protocols such as Modbus and Ethernet. It can also be combined with EMC filters to reduce electromagnetic interference, and additional cooling systems for extended use in harsh environments.
To optimize the use of the Altivar 71 , it is essential to correctly calculate parameters such as motor torque (T), which can be determined using the formula: T=PωT = \frac{P}{\omega} P is the power in watts and ω the angular velocity in rad/s. In industrial settings, these formulas help maintain efficiency and avoid system overloads.
The Altivar 71 requires periodic maintenance to ensure optimal performance, such as cleaning heat sinks and checking electrical connections. It complies with CE regulations for electrical safety and electromagnetic compatibility, but in the case of non-CE machines, it is possible to adapt the system by adding filters and additional protection devices.
To check whether the Altivar 71 is in good condition, it is important to examine the control panel and the technical manual, which must be complete. A check of the firmware and past operating data, if available, can also provide indications of the level of wear. In general, Schneider Electric produces reliable and durable equipment, so a used one of this type represents an excellent opportunity.
The Altivar 71 is used in various industrial sectors, including manufacturing, mining and water management. Purchasing a used model allows you to obtain high performance at a lower cost than new, and thanks to the quality of Schneider construction, it can last for many years even under harsh conditions of use
