The 65kA SCCR rating ensures compliance with stringent safety standards, while the Type 4 enclosure provides reliable operation in harsh environments. Door-mounted pilot devices include a PSTX keypad for setup and monitoring, a Hand-Off-Auto selector switch, start/stop pushbuttons, and pilot lights for power on, run, and fault status. The detachable keypad allows external adjustments without process interruption, enhancing operator safety. Features like slow-speed forward/reverse jog and torque control enable precise control for pumps, compressors, and conveyors, reducing mechanical stress and water hammer. Conformal-coated electronics protect against dust, moisture, and corrosive atmospheres, increasing reliability. Ideal for centrifugal pumps, compressors, and conveyor systems, the PSTX softstarter ensures smooth acceleration/deceleration to extend equipment lifespan. Dimensions: 24x20x12 inches. Manufactured in the US.

The softstarter PSR6-600-70 has a rated maximum operational current of 6 A with an operating voltage span from 208...600 V AC. The rated control voltage is between 100...240 V AC at 50/60 Hz. PSR features a two-phase control soft start and stop through a voltage ramp. It has built-in bypass for easy installation and energy saving. A RUN signal is available from a relay output in NO (normally open state). The start/stop ramp and time is easy to set by three potentiometers on the front. PSR is often used in combination with a manual motor starter (MMS) from ABB, so mechanical connection kits are available. Another popular option is Fieldbus communication, which can be enabled by an external adaptor and a Fieldbus plug. The PSR range is our most compact softstarters with basic functionality and values. They are suitable for small three-phase motors with nominal currents from 3...105 A and can manage up to 100 starts per hour. Common applications are, for example, pumps, fans, compressors, and conveyors.
