Description
Product PSTX105-600-70 Softstarter
The softstarter PSTX105-600-70 has a rated maximum operational current of 105 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 normally open (NO) state.
The PSTX has 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.
Interaction is through a detachable full graphic display with IP66 and 4x outdoor rating. Communication methods include hardwire inputs Start/Stop/Reset of fault and three programmable digital inputs, built-in Fieldbus communication Modbus RTU with optional ANYBUS modules for protocols like Profinet, Profibus, Modbus TCP, Ethernet IP and more, or via an external adapter and Fieldbus plug.
This softstarter 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.
