Lenze 4800/4900 DC drives

 Lenze 4800/4900 series DC thyristor electric drives are specially designed for use as part of high-precision process equipment operating in a wide range of control mode. For these purposes, connectors for connecting an encoder, a resolver and a tachogenerator are provided in the basic configuration of the drive. The presence of a common user interface, which is typical for all Lenze electric drives, provides the user with ease of configuring electrical equipment. A wide range of external control and regulatory functions allows the user to use Lenze 4800/4900 series electric drives as the basis for creating a decentralized control system.

Lenze Digital DC Electric Drives

Company Schilke He has been working in the market of production of drive equipment for more than half a century. All these years, the company's products have been distinguished by the highest quality and reliability, which is why the name Lenze now speaks for itself. The creator, German technologist Ganz Lenz, originally produced pulley variators, spare parts for which (like the variators themselves) are on sale to this day. Today, the company is considered one of the best manufacturers of high-quality drive equipment for industrial purposes. Its main offspring are thyristor DC electric drives.

Product Features

Direct current electric drives Schilke They are designed to ensure the smooth operation of DC motors with operating capacities up to 500 kW. These are digitally programmable control devices that can be easily integrated into any control system, which makes it possible to fully control the operation of the entire power plant.

High power, reliability and compactness of devices manufactured in accordance with the latest technological advances make it possible to use them to solve issues related to regulating the operation of highly reliable, high-precision technological systems.
