How a Soft Starter Works A soft starter is used to start and stop electric motors in a controlled manner. When an electric motor is started directly (DOL), a high inrush current can occur, often several times higher than the motor’s rated current. This can lead to mechanical stress on the installation and voltage dips

How a Brake Chopper (Braking Unit) Works A brake chopper or braking unit is used in drive systems with a variable frequency drive (VFD) to safely dissipate excess energy. When an electric motor decelerates or needs to hold a load, energy can be fed back into the drive. This energy increases the voltage in the

In ventilator applications, the airflow varies based on occupancy, climate, and/or production requirements. To make the airflow as efficient as possible, it is important to control the fans.

How a line reactor works A line reactor (also known as a choke or AC reactor) is used in electrical drive systems to reduce current peaks and minimize power quality issues. In installations where a variable frequency drive (VFD) is used, the current can fluctuate significantly due to the switching of power electronics. A line

How a Mains Filter Works A mains filter is used in electrical installations to reduce disturbances on the power grid. Electronic power control systems such as a variable frequency drive can generate high-frequency interference that flows back into the grid via the supply cable. These disturbances are also referred to as electromagnetic interference (EMI). A

Variable Frequency Drive (VFD) for Compressors Compressors are used in industrial installations to supply compressed air for a wide range of applications, such as pneumatic drives, production processes and automation systems. Traditionally, a compressor is connected to a storage tank. When the maximum system pressure is reached, the compressor switches off, and switches back on

A characteristic of a winch is that there must always be good control over the load, even at low speeds.

Variable Frequency Drive (VFD) for Conveyors Conveyors are used in industrial installations to transport products reliably from one point to another. The capacity and speed of a conveyor often need to be adjusted to match the production process, for example in sorting, packaging or processing applications. With a variable frequency drive (VFD), the conveyor speed

Variable Frequency Drive (VFD) for Pumps Pumps are used in industrial installations to transport liquids, for example in process plants, cooling systems and water treatment. A pump is typically selected for a specific flow rate at a certain head. In traditional systems, flow is often controlled using valves or throttling devices. With a variable frequency
