ABB Soft Starters – Created to Increase your Motors Lifetime

ABB’s PSTX, PSE and PSR Ranges of Soft Starters have been designed to help increase your motor’s lifetime by protecting it from the continual stresses caused when starting. This is done by letting you optimise your motors starting currents, which with conventional starting methods applies lots of stress on the motor and the associated electrical network.

The dependable and field proven PSTX, PSE and PSR Ranges of Motor Starters are packed with innovative built-in motor protection features to ensure that your installation is kept safe. These capable Soft Starters are also installation-friendly and easy to use, cutting your assembly and start-up time considerably. With everything that you need in one unit, from bypass contactor to overload protection, a single Soft Starter makes for a compact complete and cost-effective Motor Starting solution.

Furthermore, with many application specific features, such as torque control and pump cleaning these Soft Starters can ultimately help you increase productivity, throughput and much more than simply Soft Starting. These Starters are ideal for numerous industrial and commercial motor starting applications from processing line conveyor systems to liquid pumps found in food and beverage installations.

Soft Starter issue? The Siemens Sirius 3RW5 Range is the Solution…

The Siemens Sirius 3RW5 range of soft starters, with their intelligent functions, offers the perfect soft starter alternative for almost any application, from simple installations to sophisticated drive requirements such as heavy-duty starting. These dependable soft starters allow you to start three-phase motors easily, reliably and smoothly. Packed with features the 3RW5 soft starters provide a range of features including automatic parameterisation, pump cleaning, and condition monitoring, making these soft starters ideal for pumps, compressors, fans, conveyors, wastewater systems and for applications the food and beverage industry.

Versatile, the Siruis 3RW5 range encompasses all of the performance classes up to 1,200 kW, ideal for a multitude of industrial applications a few examples are summarised below.

Compressor – Condition Monitoring
Designed to excel, you can evaluate the electrical data and motor active power of the soft starter, giving you the ability to condition monitor your equipment’s status. You can assess if a pump is running dry or a bearing is showing signs of fatigue and damage.

Conveyor Belt –  Automatic Parameterisation
The soft start-up of conveyor belts must constantly adjust to new conditions as the starting weight changes. Using the 3RW5 auto-parameterisation function the soft starter identifies the load conditions and sets the appropriate values for optimally starting.

Sawmills – Integrated Braking
Heavy saw blades used in industrial sawing installations need a soft starting function to protect electrical and mechanical systems and you need to be able to stop saw blades quickly, the 3RW5 soft starters automatically supports DC braking and reverse braking.

Wastewater – Pump Cleaning
In wastewater applications, dirt and particles can be deposited on the pump blades reducing capacity. The pump cleaning function prevents this; integrated measurement technology detects the dirt and changes the direction of rotation as soon as limits are exceeded.

Water Supply – Pump Stop
Shutting down water pump systems can be challenging, pumps in these installations can stop immediately resulting in water hammer in pipes, couplings and valves. To prevent damage the 3RW5 range of soft starters have a pump-stop function that makes it possible to bring pumps to a controlled stop.
