The ideal soft starter for Every Application

SIRIUS 3RW soft starters are a cost-effective alternative to using direct or wye-delta starters for starting three-phase motors. They avoid undesirable side effects such as mechanical bumps in the machine and mechanics or voltage drops in the mains supply. The soft start in control cabinets can be implemented in almost any application in a simple and practical way with our complete soft starter range.

Products Description
 
 
 
 
 
 
Description
1. A motor soft starter is a device used with AC electrical motors to temporarily reduce the load and torque in the powertrain and electric current surge of the motor during start-up. This reduces the mechanical stress on the motor and shaft, as well as the electrodynamic stresses on the attached power cables and electrical distribution network, extending the lifespan of the system.
2. A soft starter continuously controls the motor's voltage supply during the start-up phase. Electrical soft starters can use solid state devices to control the current flow and therefore the voltage applied to the motor.
3. Digital Soft Starter
4. Compact soft starter | 3 phase 15kW/10HP
5. Another way to limit motor starting current is a series reactor.
 
 
 
 
Application
Soft starters can be set up to the requirements of the individual application. Compared to variable-frequency drives, soft starters require very few user adjustments. Some soft starters also include a "learning" process to automatically adapt the drive settings to the characteristics of a motor load, to reduce the power inrush requirement at the start. In pump applications, a soft starter can avoid pressure surges, also known as water hammering. Conveyor belt systems can be smoothly started, avoiding jerk and stress on drive components. Fans or other systems with belt drives can be started slowly to avoid belt slipping as well as air pressure surges. Soft starters are seen in electrical R/C helicopters, and allow the rotor blades to spool-up in a smooth, controlled manner rather than a sudden surge. In all systems, a soft start limits the inrush current and so improves stability of the power supply and reduces transient voltage drops that may affect other loads.
