PSR9-600-70 Softstarter: Compact Motor Starting Solution for Industrial Applications
Industrial motor control systems require reliable, energy-efficient, and compact solutions to ensure smooth operations. The PSR9-600-70 Softstarter from ABB is designed to deliver dependable motor starting and stopping performance for a wide range of industrial applications. With its compact design, built-in bypass functionality, and simple setup process, the PSR series has become a preferred choice for engineers and facility managers worldwide.
The PSR9-600-70 model is specifically engineered for small three-phase motors and offers efficient soft-start and soft-stop functionality while minimizing electrical and mechanical stress on connected equipment.
Overview of the PSR9-600-70 Softstarter
The PSR9-600-70 softstarter features a rated maximum operational current of 9 A and supports an operating voltage range from 208 to 600 V AC. The rated control voltage ranges between 100 and 240 V AC at 50/60 Hz, making it suitable for diverse industrial power systems.
Designed with ABB’s proven motor control technology, the PSR series provides two-phase controlled soft starting and stopping through a smooth voltage ramp. This helps reduce motor inrush current and mechanical wear during startup and shutdown operations.
The product is part of ABB’s compact PSR softstarter range, which supports nominal motor currents from 3 A to 105 A and can handle up to 100 starts per hour.
Key Features of the PSR9-600-70
1. Two-Phase Control Soft Start and Stop
One of the most valuable features of the PSR9-600-70 is its two-phase control technology. The softstarter gradually increases and decreases voltage during motor startup and shutdown. This reduces:
- Mechanical stress on shafts, belts, and gears
- Electrical stress on the power network
- Voltage dips during motor startup
- Water hammer effects in pump systems
The controlled voltage ramp improves equipment lifespan and enhances operational stability.
2. Built-In Bypass for Energy Efficiency
The PSR9-600-70 includes an integrated bypass contactor, which automatically bypasses the softstarter after the motor reaches full speed. This provides several advantages:
- Reduced heat generation
- Lower power losses
- Increased energy efficiency
- Simplified installation
- Compact panel design
The built-in bypass eliminates the need for external bypass components, saving both space and installation costs.
3. Easy Configuration and Operation
ABB designed the PSR series for simplicity and convenience. The PSR9-600-70 includes three front-mounted potentiometers that allow operators to easily configure:
- Start ramp time
- Stop ramp time
- Initial voltage level
This intuitive setup process enables quick commissioning without requiring advanced programming knowledge.
4. Relay Output RUN Signal
The unit features a RUN signal relay output in a normally open (NO) configuration. This output can be used for:
- Status indication
- External monitoring
- PLC integration
- System automation
The relay signal helps improve process visibility and operational control in industrial systems.
5. Compact Design for Space-Saving Installations
The PSR series is known for its compact footprint. In industrial control panels where space is limited, the PSR9-600-70 offers an ideal solution without compromising performance.
Its compact size also simplifies retrofitting projects and modernization of existing motor control systems.
Integration with ABB Manual Motor Starters
The PSR9-600-70 is commonly used together with ABB Manual Motor Starters (MMS). ABB provides dedicated mechanical connection kits that simplify the installation process and ensure seamless compatibility between devices.
This combination creates a reliable and compact motor protection and starting solution suitable for many industrial environments.
Fieldbus Communication Capability
Modern industrial automation often requires advanced communication capabilities. The PSR9-600-70 can support Fieldbus communication through:
- External communication adaptors
- Fieldbus plugs
This allows integration into industrial automation systems for remote monitoring, diagnostics, and control.
The communication capability makes the PSR softstarter suitable for smart industrial applications and Industry 4.0 environments.
Common Industrial Applications
The PSR9-600-70 softstarter is widely used in applications where controlled motor starting and stopping are critical. Typical applications include:
Pumps
Soft starting minimizes water hammer and pressure surges in pumping systems, protecting pipes and valves.
Fans
Controlled acceleration reduces belt wear and mechanical stress in ventilation systems.
Compressors
Smooth startup lowers electrical stress and helps improve compressor reliability.
Conveyors
Soft starting prevents sudden jerks and protects transported materials and conveyor components.
Because the PSR series supports up to 100 starts per hour, it is well-suited for demanding industrial operations with frequent motor cycling.
Benefits of Using the PSR9-600-70
Businesses that implement the PSR9-600-70 can benefit from:
- Improved motor lifespan
- Reduced maintenance costs
- Lower energy consumption
- Reduced electrical network disturbances
- Simplified installation
- Compact control panel design
- Enhanced operational reliability
These advantages make the PSR9-600-70 a practical and cost-effective motor starting solution for small three-phase motors
