Complete motor protection
The PSTX offers complete motor protection in only one unit and is able to handle both load and network irregularities. PT-100, earth fault protection and over/under voltage protection along with many other functions keep your motor safer than ever.
Three types of current limit
PSTX offers three types of current limit: standard, dual and ramp. This gives you full control of your motor during start. It also allows you to use your motor in weaker networks.
Built-in bypass saves time and energy
When reaching full speed, the PSTX will activate its bypass. This saves energy while reducing the softstarter’s heat generation. With the PSTX, the bypass is built-in and verified by ABB, saving you time during installation and providing space in your panel.
Easy-to-use and detachable keypad
A user-friendly and clear display saves you time and resources during both setup and operation. The detachable keypad is standard on all PSTX softstarters.
Complete control of pumps
It’s time to use your processes to their full potential. The PSTX features many application enhancing features, including torque control: the most efficient way to start and stop pumps. The pump cleaning feature can reverse pump flow and clean out pipes, securing uptime of your pump system.
Jog with slow speed
The slow speed forward and backward jog feature will give you more flexibility when operating e.g. conveyor belts and cranes. The PSTX provides positioning capabilities, letting you take control of your process.
Keyhole mounting for quick installation
The PSTX is simple and quick to install using keyhole mounting, saving you valuable time during the installation.
A compact motor starting solution
When your application reaches full speed, a bypass will reduce the softstarter’s energy consumption. It also reduces heat generation, which means you can save money by reducing the need for added cooling equipment. With the PSTX, the bypass is built-in and verified by ABB.
Clear markings on the front
With the PSTX, you do not need a manual to handle control circuit connections. With the self-explanatory markings on the front you can verify that the connections are done right. And with basic data on the front, identification is simple without having to take the product down.
The PSTX has 17 pre-installed languages along with options to customize your own specific home screens (up to seven unique screens). You can use your customized home screens to show status information important to your process – and hide information that is not.
Easy to learn
A large graphical display along with built-in assistants make learning how to handle the PSTX fun and simple. The interface resembles other interfaces from ABB that streamline and help with training of field personnel.
The PSTX comes with a detachable keypad as standard. It can be placed on your panel door, meaning you do not have to interrupt your process in order to read status information or to change settings.
