　　SPV8R-390 Intelligent Soft StartPower 160KW, current 300A, external dimensions 220 * 432 * 247. It is a low-voltage motor control device launched by Songpu Technology, providing a compact, stable and reliable soft start solution for the control of low-voltage motors. Here is its product introduction:

Application areas: It can meet the starting needs of modern industry for small and medium-sized fans, pumps, and other general machinery, and is widely used in industries such as power, metallurgy, mining, building materials, petrochemicals, and municipal engineering.

Features

Multiple starting modes: limited current starting, current ramp starting, voltage ramp starting, sudden jump starting, voltage current limiting dual closed-loop starting, etc. Suitable starting methods can be selected according to different load characteristics and application scenarios.

Soft stop function: By gradually reducing the voltage to achieve smooth shutdown, eliminate water hammer effect, protect pipeline system, suitable for equipment with high requirements for shutdown process such as water pumps.

Comprehensive protection function: equipped with multiple protection functions such as overload protection, phase loss protection, overheating protection, etc. For example, by using an internal thermal relay to detect the temperature of the thyristor radiator, once it exceeds the allowable value, the thyristor will be automatically turned off and an alarm signal will be issued.

Energy saving operation mode: When the load rate is less than 40%, the output voltage is automatically reduced to 80% of the rated value to achieve light load energy saving. After the motor reaches its rated speed, it can automatically switch to the bypass contactor for power supply, reducing the power consumption of the soft starter.

Communication function: Equipped with RS485 Modbus communication port as standard, data can be transmitted through the standard interface to achieve remote control, monitoring, and adjustment functions, making it easy to integrate into automation control systems.

Technical Specifications

Rated voltage: Suitable for various power supply voltages, such as 220V, 380V, 660V, etc., depending on the product model and application requirements.

Rated current: SPV8R-390 intelligent soft starter of different models has different rated currents, which can be selected according to the controlled motor power.

Cycle: Suitable for 50Hz and 60Hz power supplies.

Acceleration time and stop time: The acceleration time can be set according to the load condition and starting current demand of the motor, generally between 1-10 seconds; The stopping time can be set according to the motor's moment of inertia and load conditions, usually between 0.5-5 seconds.
