Main features:

Using digital microprocessors to manage data and communication, adopting signal grading processing and isolation technology, the system has strong anti-interference ability. And the equipment control is real-time, efficient, stable, and highly reliable.

Adopting advanced fiber optic transmission control technology, the triggering and detection of high-voltage thyristors, as well as the safe isolation between high and low voltage control circuits, are achieved with high safety.

Adopting high-frequency power isolation and transmission technology to provide safe and reliable working power for electronic devices operating in the high-voltage section.

The static and dynamic voltage equalization and absorption technology of the resistor capacitor network ensures the reliable and safe operation of power devices in series under high voltage.

Adopting electronic EVT (Electronic Voltage Transformer) technology, the electronic sampling fiber optic transmission is interference free and phase shifted.

Six starting curves, adapted to the mechanical characteristics and requirements of different motor systems, automatically adjust the maximum torque of the motor to obtain a smooth acceleration curve and reduce electrical and mechanical shocks during the starting process.

Six stop curves to adapt to different mechanical characteristics of loads, with adjustable final torque function, effectively preventing water hammer effect caused by pump load shutdown.

● Pulse jump function to increase the initial starting torque. Suitable for high static resistance torque systems.

● Comprehensive protection functions: There are overvoltage, undervoltage, multiple overload protection curves, as well as undercurrent, phase failure, phase imbalance, phase sequence error, zero sequence grounding protection, thyristor overheating, long starting time, starting interval limit, thyristor fault protection, etc.

The SHMV-DN series medium high voltage solid-state soft starter cabinet can be simulated and debugged using a low voltage (380V) motor before on-site high voltage operation, providing technical data and guarantees for formal operation.

The cabinet adopts the KYN28A-12 structural type, and the material is made of aluminum plate, which has the advantages of corrosion resistance, oxidation resistance, novel external structure, beauty, and high protection level. And it can be conveniently combined with KYN28A-12 standard central cabinet.

For generator power supply scenarios, there is a special control program that can successfully start in situations where voltage, current, and frequency are unstable.

● Dual parameter adjustment function: For dual speed motors, or in situations where power is supplied by the grid/generator, or when the parameters of the two motors are different during one to two operation, two sets of start and stop parameters can be input, and the required set of parameters can be easily retrieved through programmable terminals for starting operation.

● Friendly human-machine interface, historical data statistics and queries. If necessary, a touch screen interface can be added for better human-machine information exchange.

Equipped with RS485 interface and optional communication protocol (Modbus/Pro fi bus), it facilitates centralized monitoring for users.
