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.
