Soft starters: The better way to start, with less wear and tear
Nowadays, the three-phase motor is the optimal drive used to implement machine and system concepts in a straightforward and economical manner. However, in many cases, direct-on-line or even star-delta starting are not the best solutions to avoid pressure surges in pump installations, reduce starting current peaks with large rotating masses or ensure that mechanical handling equipment starts up without a jolt, for example.
This is where softstarters provide the smooth alternative in virtually every situation, preventing jerky motor starting while going easy on the supply system. Using them, you are cutting operating costs in several ways.
The DS4 and DM4 devices cover the complete rating range from 2.2 kW to 900 kW, and their approval to global Standards ensures that they can be used throughout the world.
Soft starter DS7 – now up to 200 A
The new soft starter DS7 is ideal for pumps, fans and small conveyor applications. The DS7 is a fully integral element in the xStart system. It replaces the mechanical contactor and extends the function “Motor soft start”.
Extended service intervals and reduced operating costs are welcomed side effects.
Soft starter DM4
Top-quality soft starters such as the DM4 series can be individually matched to the requirements of the respective applications, and offer soft starting in its most comfortable form. A specific motor current reduction in the start phase and an application specific parameter definition ensure optimum matching to the characteristics of the three-phase drive. The DM4 can be used in the In Delta and In Line configurations.
The highest level of operating comfort, optional communication modules and motor protection functions which are already integrated, assure simple and safe handling of the drive.Soft starter DM4
