ABB Soft Start
Alternating Current motors, the workhorse of the industry, are used to drive fans, crushers, agitators, pumps, conveyors etc. Depending on how it is installed, too often unnecessary and unwanted torque and current peaks is an everyday reality in production plants all over the world, causing damage in several ways:
Electrical problems due to voltage and current transientarising from Direct-On-Line or Star-Delta starts. Suchtransients may overload the local supply network andcause unacceptable voltage variations that interfere withother electrical equipment connected to the network.
Mechanical problems that address the entire drive chain,from motor to driven equipment, causing a big needfor service and repair as well as unwanted down time.
Operational problems, such as damage to products onconveyor belts.
Water hammering and pressure surges in pipe systemswhen starting and stopping pumps.The financial consequences are considerable; every technicalproblem and every breakdown costs money in terms of repairsas well as lost production.
The easy solution to all of these problems is to install an ABB soft starter type PSR, PSE or PST(B). With ABBsoft starters, it is possible to start and stop smoothly while keeping mechanical and electrical stresses to a minimum.
ABB PSR Soft Start
PSR – The compact range, 3 to 105 Amps
The ABB PSR soft starter is the most compact of all the ABB soft starter ranges, thereby making it possible to design compact starting equipment. The system concept with ManualMotor Starters and the PSR provides a far more compact starting solution than forinstance a star delta starter.
Built-in by-pass reduces the energy loss and makes the connection easier and withonly three potentiometers the set-up couldnt be any easier. Still, the optimizedramping characteristics will ensure a very smooth start and stop for all applications.
ABB PSE Soft Start
PSE The efficient range, 18 to 370 Amps
The ABB PSE soft starter is the worlds first compact soft starter with both built-in elec
tronic overload for motor protection and torque control for an excellent control of pumps.The compact design with the most important functionality integrated provides a very efficient starting solution.
The illuminated language neutral display and the four button keypad make it easy totake advantage of all the advanced functionality in the soft starter.
The display will alsoprovide all the necessary information both during ramping and continuous operation.
ABB PST(B) Soft Start
PST(B) The advanced range, 30 to 1050 Amps
The ABB PST(B) soft starter is the most advanced ABB soft starter in the range with almost all imaginable functionality included. All the advanced protections for the motor, the soft starter and the load ensure a trouble free operation. Pre-warnings even allow problems to be detected before the motor needs to be stopped and thereby avoiding unnecessary downtime.The torque control function has been developed and tested together with well known pump manufacturers to ensure the absolutely best possible stop of pumps withoutwater hammering and pressure surges.
