Description

ABB  5SHX0860F00021  Silicon Controlled Rectifier Module

• High current adapts to medium and high-power needs: The 80A rated current can stably carry continuous loads, suitable for industrial control circuits with high current requirements, such as medium-sized motors (e.g., compressors, main motors of injection molding machines), high-power heating equipment (e.g., large industrial furnaces, metal heat treatment devices), and linkage systems of multiple small and medium-sized equipment requiring centralized control, meeting the power control needs in medium and high-power scenarios.
• Silicon controlled rectifier technology foundation: Based on the semi-controlled characteristics of silicon controlled rectifiers (thyristors), the conduction phase is precisely controlled through external trigger signals (pulse signals), realizing voltage regulation, power regulation, or motor speed regulation of AC circuits. It is especially suitable for scenarios requiring smooth adjustment of large currents (such as heavy-load starting of motors, continuously adjustable heating power).

• Fast switching and high efficiency: It inherits the “fast switching” characteristic of the 5SHX series, with fast switching response speed, which can reduce energy loss during switching, improve the overall efficiency of the system; at the same time, the on-state voltage drop is optimized, reducing power loss during continuous operation, reducing module heating, and lowering the design pressure of the heat dissipation system.
• High reliability design: Adopting ABB’s mature packaging technology and industrial-grade materials, it has a wide operating temperature range (adapting to harsh environments such as -40℃~+125℃), vibration resistance, and humidity resistance, and can operate stably in complex industrial scenarios with dust and electromagnetic interference, ensuring long-term reliable operation.

• Advantages of modular integration: It integrates silicon controlled rectifier chips, electrodes, and insulation structures, eliminating the need for users to build complex discrete circuits, simplifying the system integration process, reducing design difficulty and cost, and facilitating rapid deployment in production lines or equipment control circuits.
• Compatibility with standardized control: It supports conventional pulse triggering methods and can be directly connected to pulse output modules of industrial control systems such as PLC and DCS, realizing remote programming control or closed-loop regulation (e.g., combining with sensors to achieve automatic feedback control of temperature and speed).
• Enhanced heat dissipation adaptability: Aiming at the heating characteristics under 80A current, the packaging design reserves a larger heat dissipation contact surface, which can be matched with large radiators or water-cooled heat dissipation systems, ensuring that the temperature is stable within a safe range during full-load operation and avoiding performance degradation caused by overheating.

• Medium and high-power motor control: Used for speed and torque control of medium-sized AC motors, such as compressors, fans, pumps, etc. By adjusting the conduction angle of the silicon controlled rectifier, smooth speed regulation is achieved, reducing current impact during heavy-load starting, and protecting the motor and transmission system.
• High-power heating control: Suitable for power regulation of large industrial heating equipment (e.g., metal heat treatment furnaces, heating units of chemical reactors). It realizes closed-loop temperature control by precisely controlling heating power, improving process stability.
• Industrial equipment linkage systems: In scenarios of multiple production lines linkage and centralized control of multiple equipment, it serves as the core component of power control to uniformly adjust the power supply of each equipment, ensuring the coordinated operation of the system (e.g., conveyor clusters in automated warehouses, auxiliary equipment groups in automobile production lines).
