Comprehensive Motor Protection Functions Ensuring Motor Reliability Improving Installation Efficiency Enhancing Equipment Productivity PSTX integrates comprehensive motor protection functions to handle abnormal load and power grid conditions. PT-100, ground fault protection, overvoltage/undervoltage protection, and other functions ensure your motors are safer. PSTX offers three current limiting modes: standard, dual current limiting, and current ramp. This helps you fully control motor starting, ensuring normal motor operation even in poor power grid environments. Built-in Bypass, Saving Time and Reducing Energy PSTX activates the built-in bypass when the motor is running at full speed. This reduces energy consumption by minimizing soft starter heat. PSTX's built-in bypass is rigorously verified by ABB, helping you save installation time and reduce control cabinet size. Perfect Pump Control Functions Unleash greater potential and improve your equipment's productivity. PSTX features many special functions that enhance productivity, such as torque control. This is a more efficient way to control pump start-up and shutdown. The water pump cleaning function cleans the pipes by reversing the flow of water from the pump, ensuring the water pump system's uptime.
