Eaton DS7 Soft Starter Series Extended with Devices up to 200 A
Bonn . . . As one of the leading manufacturers of components, systems and solutions for electrical engineering and automation, Eaton's Electrical Sector today announced the expanding of the soft starter series DS7 with devices up to 200 A. The soft starter is increasingly becoming established as an alternative to the star-delta starter.
Users are thus provided with a complete system from 4 to 200 A with a standard actuation and functionality that will fully replace the previous DS4 and DS6 series. The supply voltage on the DS7 ranges from 200 to 480 V, and versions with 24 V AC/DC and 110-230V AC actuation are available.
The special starting method (asymmetrical trigger control) for the soft starter function prevents DC components that normally occur with a two-phase controlled soft starter (Eaton EU patent EP12 40706B1). This prevents the formation of elliptical rotation fields which cause uneven motor startups and unnecessarily long starting times. The smooth starting behavior of the DS7 is thus similar to that of a three-phase soft starter.
The compact DS7 starters are ideally designed for regular applications such as pumps, fans and small-scale conveyor belts. The DS7 will soon also be available with a SmartWire-DT interface for automation solutions, thus simplifying wiring and increasing functionality.
Eaton DS7 soft starters are suitable for a number of applications such as three-phase inductive loads, noise-free and smooth motor starting in transport and conveyor systems, or a wear-free pump start, which reduces the load on the entire installation (water hammer). DS7 starters are also predestined for starting fan drives with less wear on the drive belts.
Electronic soft starters meet the customer requirements for jerk-free torque increases and selective current reduction in the startup phase. They control the supply voltage of the three-phase motor in the startup phase so that the motor is adjusted to the load behavior of the working machine. This enables the speed of mechanical equipment to be increased gently. The use of the soft starter reduces the load on all operating characteristics and operating sequences so that the associated components have a longer service life with a resulting reduction in costs. DS7 soft starters fully meet the product standard for electrical soft starters (IEC / EN 60 947-4-2.).
