1, Introduction: 
 The voltage in the low coverage of AC0.22kV ~ AC15kV very wide range (2.3kV medium voltage products above), cover 40A ~ 1600A current range to meet all industrial and agricultural production in the motor starting requirements. 
 KYDS series soft starter, the control center using the most advanced control ASIC, pure 32-bit DSP digital signal processors, computing, high precision, fast response, small size, control functions, using a small number of electronic components, reliable high. All-digital design, all parameters and functions, the choice of the state are set by the keyboard. 
 All-digital operation display, a variety of states, parameters, data can be displayed on the screen, intuitive display, large amount of information. Meanwhile, the touch key design, beautiful appearance, easy operation. 
 Products designed to control and protection functions. Well-made products, through the national certification authority of the rigorous testing and certification. Products comply with GB, IEC, EN and other standards. 
 2, functional 
 2.1, control: 
 Starting current limit function; voltage ramp start; current ramp start; torque ramp start; pump control functions; multi-parameter configuration (by a device start four different power levels, different starting characteristics of the motor); pulse-start function; Energy-saving operation (optional); regulator operation (optional); speed operation (optional); braking (optional); communication (optional). 
 2.2 Protection: 
 Over-current protection; over voltage protection; phase protection; undercurrent protection; under-voltage protection; overload; overheating protection; current imbalance; ground protection; the number of starts protection; bypass open; thyristor damage; phase sequence error; motor connection fault; starting out; start the motor stall; short-circuit protection; fault. 
 2.3, the device features: 
 All-digital display, suitable for various domestic and international users; high and low fiber-optic connection, a high degree of isolation; 
 Control diverse, flexible; 
 The pressure in the low-voltage device (AC380V) under the conditions of the device fully functional test; output (initial) voltage of 0V to rated voltage at full voltage is adjustable for any load, no-load operation (in particular air motor) is particularly important when you can truly start no impact. 
 Intuitive Thyristor fault indication for easy maintenance; 
 You can start with a successive multiple motor unit; can start synchronous motor; 
 Multi-purpose programmable input / output interface, and optional 0 / 4 ~ 20mA, 0 ~ 10V analog input / output, user-friendly combination of systems; optional multiple communication interfaces and protocols, user-friendly network use; 
 Complete motor and system protection, always monitoring the motor and the operation of the system state; complete recording and analysis and calculation of operating parameters, user-friendly monitoring of operating status and statistics. 
 KYDS series thyristor soft-start device, using a series of the most advanced technology and devices, and through a variety of rigorous tests. The product is suitable for metallurgy, mining, petroleum, pipeline, chemical, textile, marine, municipal and other industries in fans, pumps, traction and other needs soft start or soft stop devices. Can be used as Y / Δ start, start-string reactor start-up equipment such as the ideal alternative to traditional products. It can limit the starting current, reduce the drop voltage level to ensure the safe operation of the power supply system. It can reduce the impact of starting torque, extend equipment life, reduce maintenance workload, save operating costs and improve the overall efficiency of the enterprise.
