ABB PSTX45-690-70 Advanced Range Soft Starter, 100 to 250 VAC V Coil, NEMA 1/4X/12/IP10/IP20/IP66 Enclosure

The PST softstarter is the most advanced softstarter in the ABB product portfolio and is equipped with almost all imaginable features. This makes the PST ideal for almost every applications. The ABB torque control function is developed together with pump manufacturers to ensure the best possible pump stop, eliminating problems with water hammering and pressure surges. By-passing the softstarter after reaching full voltage, will save energy and reduce the heat generation. The PST softstarters are equipped with extra terminals making the connection of an external by-pass contactor easier and allowing all protections to be active during by-pass. On the PST softstarters, an ABB AF contactor is already built-in, ensuring a compact starting solution with minimal wiring during installation. The PST softstarters are equipped with almost all protections imaginable for protecting the motor, the softstarter and the applications. To offer more flexibility, all protections can be tailored to your specific needs. The analog output terminals can be connected to an analog current meter to show the current during operation and thereby eliminating the need for an additional current transformer. The analog output signal can also be used as an analog input to a PLC. Using the ABB fieldbusplug, all the most common fieldbus protocols are supported. Using the PLC system it is possible to set-up the softstarter, read status information and also to control the softstarter. The PST softstarter is equipped with a full text display showing all information in clear text in your own language. To make it even easier to set-up, there are standard settings for many common applications, such as centrifugal pump. Selecting this will automatically provide all required settings including torque control when stopping. As an option, the PST softstarter can be equipped with an external keypad for easy set-up and monitoring of the unit without opening the enclosure door. The keypad can also be used to copy parameters between different softstarters.
