This dedicated dual power automatic transfer device is designed for medium and low power load scenarios. As a core power supply guarantee unit, it intelligently switches between main power sources and standby power sources (such as generators), delivering continuous and stable power supply protection for small and medium-sized industrial and commercial applications.
Core Configuration: Premium Components for Medium and Low Power Working Conditions
Main Switch Assembly: Equipped with Chint NXM-400S/4300B molded case circuit breaker with a rated current of 315A, it features complete overload and short-circuit protection functions. Compliant with IEC international standards, it is applicable to 400V three-phase four-wire (4P) AC power supply scenarios.
Transfer Control Unit: Adopts AISIKAI SKT1-300A/4P/X PC-grade automatic transfer switch, supporting automatic and manual switching between main and standby power sources. It delivers stable and accurate switching logic with high operational reliability.
Cabinet and Panel: Made of cold-rolled steel with powder coating, suitable for indoor power distribution environments. The panel integrates main/standby power indicator lights, voltage monitors, ABC three-phase real-time ammeters and voltage transfer switches, enabling intuitive equipment status observation and convenient operation and maintenance.
Core Functions: Intelligent Automatic Switching and Visualized Convenient Monitoring
Automatic Switching Function: It monitors the voltage and operating status of the main power source in real time. When the main power source suffers faults such as power outage or abnormal voltage, it automatically switches to the standby power source to provide uninterrupted power supply for load equipment.
Manual Operation Mode: Fitted with a manual adjustment knob, it supports manual power switching during equipment maintenance and function tests, adapting to diverse operation and maintenance scenarios.
Visual Status Monitoring: Core data including power status, voltage and current can be directly read via panel meters and indicator lights without external auxiliary equipment, greatly simplifying the operation and maintenance process.
Application Scenarios: Ideal Choice for Medium and Low Power Loads
Widely applied to small and medium-sized industrial plants, miniature production lines, supermarkets, office buildings, small data centers and community supporting facilities. It can stably bear a total power load of 150kW to 200kW, serving as a cost-effective and highly reliable power protection device for medium and low power supply scenarios.
