ABB Soft Starters
ABB Soft Starters at Kudamm Corporation
Soft Starters are essential for protecting motors and improving process reliability by providing smooth start and stop operations. At Kudamm Corporation, we supply the full range of ABB Soft Starters – PSR, PSE, and PSTX – designed to match every level of industrial requirement, from compact installations to advanced heavy-duty applications.
Type Of ABB Soft Starter
ABB PSR Soft Starter – Compact & Cost-Effective
The ABB PSR Soft Starter is ABB’s most compact model, designed for basic motor starting applications. With a built-in bypass, it minimizes power losses and reduces panel heat, making it energy-efficient and space-saving
Technical Specifications
- Operational voltage: 208…600 V AC.
- Rated operational current: 3 A … 105 A
- Control supply: 100–240 V AC (or 24 V AC/DC option).
- Built-in bypass; Run / Top-of-ramp relays
Applications
- Pumps (small/medium) — smooth start/stop, pump protection
- Fans — reduced inrush and mechanical stress
- Compressors (smaller)
- Short conveyors, elevators, bow thrusters (space-limited solutions)
ABB PSE — Efficient / Pump-oriented
PSE is optimized for pump & HVAC needs — torque control (pump stop ramp) to eliminate water hammer, built-in bypass, illuminated language-neutral display and fieldbus option.
Technical Specifications
- Operational voltage: 208…600 V AC.
- Rated operational current: 18 A … 370 A
- Control supply: 100–250 V AC
- Voltage ramp + torque control (start & stop), current limit, kick-start, built-in bypass, electronic overload and underload protection, optional external IP66 keypad, fieldbus plug option, Analog output.
Applications
- Water pumps (best use — prevents water hammer)
- HVAC systems (fans, AHUs)
- Compressors
- Material handling / conveyors
- General industrial pumps & utilities
ABB PSTX — Advanced / Heavy-duty
PSTX is ABB flagship advanced soft starter — full motor protection and intelligent features (torque control, pump cleaning, limp-mode, diagnostics, extensive communication options).
Technical Specifications
- Operational voltage: 208…600 V AC
- Rated operational current: 30 A … 1250 A
- Control supply: 100–250 V AC.
- Voltage & torque ramps, torque limit, pump cleaning, dynamic brake / motor brake, limp mode, extensive motor protection (over/under voltage, imbalance, earth-fault, PTC/PT100 support), detachable/keypad/graphical display, advanced diagnostics, fieldbus/communication modules (Modbus, others opt.)
- Built in bypass for energy saving
Applications
- Mining and heavy-industry motors
- Oil & Gas / offshore (marine approvals)
- Large water treatment plants (pump cleaning)
- Crushers, mills, heavy conveyors, large HVAC chillers/air-handlers
- Any critical/process-sensitive heavy-duty application
