Key Features

Flexible Control Modes: The starter supports nine programmable start/stop modes and three low-speed settings, enabling customization for applications like pump control or braking operations. This versatility ensures smooth motor operation while minimizing mechanical wear.
Integrated Diagnostics and Protection: With built-in electronic motor overload protection and real-time temperature monitoring, the device safeguards against faults like phase loss, stalling, or voltage fluctuations. Its conformal coating enhances durability in harsh environments.
Space-Efficient Design: The compact chassis allows DIN rail or panel mounting, optimizing control cabinet space. Optional bypass contactors further improve energy efficiency during continuous operation.
Advanced Communication Options: Through add-on modules, the starter integrates into industrial networks (e.g., EtherNet/IP, DeviceNet), enabling remote monitoring and control via PLCs or HMIs. The built-in LCD display simplifies local programming and diagnostics.
Safety Compliance: The controller meets international standards (IEC 60947-4-1) and includes features like torque control and braking options, ensuring safe operation in high-inertia applications such as crushers or mixers.

Application Scenarios

Pump and Fan Systems: Reduces water hammer and pressure surges in fluid handling systems by enabling gradual acceleration, extending pump lifespan and lowering maintenance costs.
Conveyor and Material Handling: Provides smooth acceleration/deceleration for belts and sorters, preventing product spillage and minimizing belt wear in logistics or manufacturing facilities.
Heavy-Duty Machinery: Suitable for high-torque equipment like compressors, crushers, or mixers, where controlled startups avoid current spikes and mechanical stress.
OEM Industrial Equipment: Ideal for integration into automated machinery requiring reliable motor management, with programmable logic (StepLogic) supporting standalone operation without external controllers.

Note: Specifications are based on manufacturer data and industry sources. Verify parameters against the latest technical documentation for specific applications.
