PSTX45-600-70 Softstarter Detailed Information
Description: The softstarter PSTX45-600-70 has a rated maximum operational current of 45 A with an operating voltage span from 208 to 600 V AC. The rated control voltage is between 100 to 250 V AC at 50/60 Hz. PSTX features a three-phase control soft start and stop through a voltage or a torque ramp. It has built-in bypass for easy installation and energy saving. A RUN, TOR and Event signal is available from relay outputs in normally open state.
Functions: Current limit, kickstart, analog output, EOL, motor heating, pump cleaning, jog, braking, stand-still brake, diagnostics, sequence start, emergency/fire pump mode.
Display and Communication: Detachable full graphic display with IP66 and 4x outdoor rating. Communication via hardwire inputs Start/Stop/Reset of fault, three programmable digital inputs, built-in Fieldbus communication Modbus RTU, optional ANYBUS modules for Profinet, Profibus, Modbus TCP, Ethernet IP and others, external adaptor and Fieldbus plug.
Applications: Suitable for medium to large-sized three-phase motors with nominal currents from 30 to 1250 A inline connection or 52 to 2160 A inside delta connection. Typical applications include pumps, fans, compressors, and conveyors.
