Eaton offers a compact DC frequency drives. It is specially designed for simple use. Providing exceptional ease of installation, DC is ideal for fast commissioning. The frequency drive is the ideal variant for production in engineering systems. General DC bus drives are utilized in a variety of applying and combinations. Drives that are braking can transmit the energy directly to the actuators in a motoring mode.
