Description
PSTX85-600-70 Softstarter
The softstarter PSTX85-600-70 has a rated maximum operational current of 85 A with an operating voltage span from 208…600 V AC. The rated control voltage 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 has functions such as current limit, kickstart, analog output, EOL, motor heating and pump cleaning. PSTX 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. There are four ways to communicate with PSTX: hardwire inputs Start/Stop/Reset of fault, three programmable digital inputs, built-in Fieldbus communication Modbus RTU including optional ANYBUS modules supporting major protocols like Profinet, Profibus, Modbus TCP, Ethernet IP, and others, and external adaptor with a Fieldbus plug.
PSTX is 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.
