The app lication of SCR technology makes the infinite and smooth voltage output,no current and mechanical impact, and the performance is far better than the star triangle, self-coup ling and magnetic control step-down soft rise. Intelligent technology makes the soft starter based on CR technology more consistent with the load characteristics, and realizes the real-time data monitoring, motor protection and bus control functions, making the equipment operation more reliable and better performance. This intelligent soft starter is developed based on the 32-bit DSC processor platform, and combines the latest motor control theory, motor protection technology and fuzzy control technology. The app lication of simulation software optimizes the air duct design, so that the soft starter miniaturization has higher heat dissipation ability, better performance and more stable and reliable use.
Main role
- Effectively reduce the starting current of the motor, can reduce the distribution capacity, avoid the grid capacity increase investment.
- Reduce the starting stress of the motor and the load equipment, and prolong the service life of the motor and related equipment.
- Soft shutdown function effectively solves the parking surge problem of the inertia system.
- A variety of unique starting modes, to adapt to the comp lex working conditions,to achieve a perfect starting effect.
- Perfect and reliable protection function, effectively ensure the safety of the motor and related production equipment.
- Standardized network protocol to meet the networking requirements of power automation.
Features
- Use simulation software to optimize the heat dissipation design, miniaturization at the same time have better heat dissipation ability;
- Based on the 32-bit DSC processor plat form, higher bandwidth, faster speed, make the fuzzy algorithm control more accurate;
- Use of 12-bit AD sampler, DMA data transmission mode, to achieve direct AC sampling, high real-time performance;
- Realize a wide range of linear data sampling, data collection without dead area,more accurate data ;
- All faults can be turned on and closed for easy debugging;
- Soft up can be realized according to the load of automatic overtime and force force, load adantability is stronger;
- Rich monitoring data, monitoring current and voltage can monitor phase sequence Ang le, frequency, cumulative running time and other data;
- Online operation mode, no contact adhesion phenomenon ;
- High precision 4-20MA current output capacity, linear accuracy up to 0.5% ;
- Has up to 12 kinds of protection functions, among which the reverse time limit overload protection can effectively prevent the motor from overheating and burning, the use of equipment is more assured;
- Four lines of LCD display, can achieve both Chinese and English switch display.
