The voltage covered the very wide rage of middle-low voltage AC0. 22kV ~ AC15kV (the product is medium voltage product whose voltage is above 2. 3kV), current coverage of 40A ~ 1600A scope, to meet all the motor starting requirements in industrial and agricultural.
Soft Starterof series of KYDS, whose control core uses the most advanced control chip in todays world, 32-bit digital signal processor DSP, high- precision computing , fast response, small size, strong control function, the number of electronic components is small, high reliablity.
All-digital design, the choice of all parameters, functions and states are set by the keyboard.
All-digital operation display, a variety of state, parameters, data can be showed on the screen, the showing is intuitive and informative. At the same time, light touch key design, pleasing in appearance, easy operation.
Products are carefully designed, control and protection functions are complete. Well-made products, are rigorous tested and certificated by the certification body of the authority of the State. Products comply with GB, IEC, EN and other standards.
Functions
1) Control function:
Current limit function of starting ; starting of voltage slope; starting of current slope; starting of torque slope; pump control function; multi-parameter configuration (can start four different power levels and starting characteristics motors by one device); pulse start function; Energy-saving operation (optional); voltage regulating operation (optional); speed regulating operation (optional); power brake (optional); communications (optional).
2) Protect Functions:
Over-current protection; over-voltage protection; lack of phase protection; less-current protection; less-voltage protection; overload protection; overheating protection; current imbalance; Earthing protection; the number of starting protection; bypass open; thyristor damage; phase sequence error; the connect of motor is wrong; start overtime; the motor can not run while starting; short-circuit protection; external fault.
Device Characteristics:
All-digital display, suitable for all types of users at home and abroad; high and low voltage use the fiber-optic connection, a high degree of isolation;
Variety of control means, use flexibility;
Middle-voltage device can make a full-function test under the condition of low-voltage(AC380V);
Output (initial) voltage can be adjusted in the entire voltage range of 0V to rated voltage, can be used to any load, while in no-load operation (especially the empty motor), it is particularly important, can really start-up without the impact.
Intuitive thyristor phase faultinstructions, easy maintenance;
It can use a device to multiple successive start-up several motors; can start synchronous motor;
Programmable multi-purpose input / output interface, and optional 0 / 4 ~ 20mA, 0 ~ 10V analog input / output, user-friendly combination of systems;
A variety of optional communication interface and protocols, it is convenient for the user to use the combination network;
Perfect motor and system protection, always monitor the operation state of the motor and system;
Complete recording of the operating parameters and analysis , it is convenient for the user to monitor the motor and the running state of the system.
Series of KYDS of thyristor soft-start device, use a series of the most advanced technologies and devices, and pass a variety of rigorous tests.
The product applies to the metallurgical, mining, petroleum, pipeline, chemical, textile, marine, municipal and other industries in fans, pumps, traction and other needs of soft-start or soft stop the use of the equipment. It also can serve as a Y / Δ start, string reactor start-up equipment, such as the traditional start of the ideal alternative. It can limit the starting current and lower voltage drop in the level of protection of the safe operation of the power supply system. It can reduce the start-up torque at the time of the impact of the extension of equipment life, reduce maintenance workload, saving running costs and improve the overall efficiency of the enterprise.
