Description
PSTX300-600-70 Softstarter
The softstarter PSTX300-600-70 has a rated maximum operational current of 300 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 and three programmable digital inputs; built-in Fieldbus communication Modbus RTU and optional ANYBUS modules with every major protocol such as Profinet, Profibus, Modbus TCP, Ethernet IP and others; or by using an external adaptor and a Fieldbus plug.
PSTX is the complete alternative for any motor starting application. It 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 are, for example, pumps, fans, compressors, and conveyors.
