The softstarter PSE250-600-70-1 is designed for industrial applications, providing a rated maximum operational current of 250 A and accommodating an operating voltage range from 208 to 600 V AC. The unit operates with a control voltage between 100 to 250 V AC at 50/60 Hz, making it versatile for various electrical setups.
This model features a two-phase control system that enables a smooth start and stop through either a voltage or torque ramp. With a built-in bypass function, installation is straightforward and promotes energy efficiency.
The softstarter comes equipped with a RUN, TOR, and Event signal relay output in the normally open (NO) state, facilitating efficient monitoring and control.
Moreover, the PSE is rich in protective features including current limit, kickstart, analog output, end-of-line (EOL) monitoring, underload, and locked rotor protection. Its illuminated display uses universal symbols, providing an intuitive interface regardless of language.
Communication with the PSE can be achieved through hardwired inputs for Start/Stop and fault resets, or via Modbus RTU fieldbus communication. Additionally, an external Fieldbus adaptor and plug can enhance connectivity.
As a multi-functional softstarter, the PSE250-600-70-1 strikes an ideal balance between high starting capacity and cost efficiency, making it perfectly suited for small to medium-sized three-phase motors with nominal currents ranging from 18 to 370 A. Common applications include pumps, fans, compressors, and conveyors, positioning this device as a reliable choice for diverse industrial environments.
