ABB Softstarters PSR, PSE, PSTX PSTB

ABB Softstarters PSR, PSE, PSTX PSTB

ABB’s softstarters from Sentridge Control increase a motor’s lifetime by protecting it from electrical stresses. They do so by letting you optimize starting currents that with conventional starting methods put lots of stress on the motor. With many built-in motor protection features, your motor is safe in its hands. ABB’s softstarters are also installation-friendly and can cut your assembly and startup time by being easy to use and easy to learn.

With everything that you need in one unit, from bypass contactor to overload protection, a single softstarter makes for a compact and complete starting solution. Furthermore, with many application specific features, ABB’s softstarters can ultimately help you increase productivity. Torque control, pump cleaning and many more features let you do more than simply softstarting. Easy to Fit. Easy to Program and Set Up. Just Easy.

Why Use Softstarters  compare~ Direct-on-line / Star-delta / Softstarter

differentmeans

Direct-on-line starting (DOL) is the easiest and most commonly used starting method. It is suitable for stable networks and mechanically stiff and well-dimensioned shaft systems due to the high current and torque generated during start.
DOL starting is uncontrolled, which means that the motor will start with maximum current and torque regardless of load type.

A star-delta starter reduces current and torque during start. The starting current is about one third compared to direct-on-line starting, although it also reduces the starting torque to about 25 percent.
Star-delta is not adjustable, so if the torque is reduced too much, the motor will not start. Current peaks will happen when switching from star to delta connection.

Softstarters. Like direct-on-line and star delta starters, softstarters are used to start and stop motors in full-speed applications. It eliminates common problems associated with motor starting and stopping, including electrical surges, spikes and high inrush currents.

Because it offers soft starting and stopping, a softstarter is the optimal compromise between a direct-on-line or star-delta starter and a variable speed drive in many full-speed motor applications.
