Description
PSTX142-600-70 Softstarter
The softstarter PSTX142-600-70 has a rated maximum operational current of 142 A with an operating voltage span from 208…600 V AC. The rated control voltage range is between 100…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 NO (normally open state). The PSTX includes functions such as current limit, kickstart, analog output, EOL, motor heating, and pump cleaning. It also features jog, braking, stand-still brake, diagnostics, sequence start, and emergency/fire pump mode as standard.
To interact with PSTX, it has a detachable full graphic display with IP66 and 4x outdoor rating. Communication can occur via hardwire inputs Start/Stop/Reset of fault and three programmable digital inputs. A popular option is the built-in Fieldbus communication Modbus RTU including optional ANYBUS modules with major protocols such as Profinet, Profibus, Modbus TCP, Ethernet IP and others. Another way to communicate is by using an external adaptor and a Fieldbus plug.
PSTX is a complete alternative for any motor starting application. It is suitable for medium to large-sized three-phase motors with nominal currents from 30…1250 A inline connection or 52…2160 A inside delta connection. Typical applications include pumps, fans, compressors, and conveyors.
