The PSE300-600-70-1 is a versatile softstarter designed for general-purpose use with small to medium-sized three-phase motors. It supports a wide operating voltage range of 208 to 600 V AC and handles up to 300 A of operational current. The control voltage ranges from 100 to 250 V AC at 50/60 Hz.
Featuring two-phase control, the PSE offers smooth soft start and stop via voltage or torque ramping. Its built-in bypass simplifies installation and reduces energy consumption. Status indicators (RUN, TOR, and Event) are provided through a relay with a normally open (NO) contact.
Advanced functions include current limiting, kickstart, analog output, end-of-life (EOL) detection, underload protection, and locked rotor protection. A user-friendly illuminated display uses intuitive symbols for easy, language-independent operation. An optional IP66-rated external keypad is also available for convenient remote control.
Communication with the PSE is flexible: use hardwired Start/Stop or Fault Reset inputs, built-in Modbus RTU fieldbus communication, or connect via an external adapter and Fieldbus plug.
Striking the ideal balance between performance and cost-efficiency, the PSE softstarter is perfect for applications such as pumps, fans, compressors, and conveyors, supporting motor currents from 18 to 370 A.
