The softstarter PSE37-600-70 has a rated maximum operational current of 37 A with an operating voltage range from 208 to 600 V AC. The rated control voltage is between 100 and 250 V AC at 50/60 Hz. PSE features a two-phase control with a soft start and stop through a voltage or torque ramp. It has a built-in bypass for easy installation and energy saving. A RUN, TOR, and event signal is available from a relay output in normally open state. The PSE includes functions such as current limit, kickstart, analog output, end of line, underload, and locked rotor protection. To interact with PSE, it has an illuminated display that uses symbols to ensure language neutrality. As an option, you can add an identical external keypad with a rating of IP66. There are three ways to communicate with PSE: through hardwire inputs for start/stop or reset of fault, built-in fieldbus communication Modbus RTU, or using an external adaptor and fieldbus plug. PSE is a true general-purpose softstarter, offering a perfect balance between high starting capacity and cost efficiency. It is very suitable for small to medium-sized three-phase motors with nominal currents from 18 to 370 A. Typical applications include pumps, fans, compressors, and conveyors.
