Review

The RD11 UNI series is a frequency converter designed for use in HVAC systems and for industries where high overload is required. These drives can be connected to three-phase 380V, 690V and 1140V, their power can vary from 0.75 to 1120 kW. Depending on the needs, they can be performed with normal or increased overload. The presence of an integrated RS-485 network interface makes it easy to integrate the drive into the system.

The RD11 UNI supports control of both asynchronous and synchronous motors. These drives have a compact design that allows the installation of devices close to each other without loss of functionality. In addition, they are equipped with a separate cooling system, which prevents the passage of air flow through electronic components and significantly increases the service life of the drive. The drive can operate at ambient temperatures up to +50C, due to the fan cooling system, which in turn are easy to maintain and easy to remove and replace.

Due to an electromagnetic compatibility filter, a brake unit and a convenient operator panel with a potentiometer or graphical keyboard, the RD11 UNI model is put into operation much faster and at lower cost.

In addition, the drive has a modular structure, which allows you to expand its functionality with additional boards.

The frequency converters of this line can automatically adapt to the engine, regardless of its current rotation, which greatly facilitates and speeds up the process of putting it into operation. The presence of an integrated DC choke (for power from 55 kW and above) helps to reduce the level of harmonic distortion to less than 45% THiD and extend the service life of the frequency converter.
