Automatic Transfer Between Two Power Sources for Continuous Power Supply
A Dual Power Automatic Transfer Switch (ATS) is an intelligent power switching device designed to automatically transfer electrical loads between two independent power sources. When the primary power supply fails or becomes abnormal, the ATS quickly switches to the backup power source, ensuring continuous and stable power supply for critical electrical equipment.
Designed for residential, commercial, and industrial applications, this compact DIN rail mounted ATS provides a safe, fast, and reliable solution for automatic power management.
Product Overview
The Dual Power Automatic Transfer Switch monitors two power inputs in real time and automatically selects the available power source to supply the connected load.
It is widely used with:
- Utility power + generator systems
- Utility power + UPS systems
- Solar power backup systems
- Emergency power systems
- Industrial control equipment
- Residential backup power applications
With intelligent control technology and a compact modular design, this ATS provides seamless power switching while reducing downtime caused by power interruptions.
Key Features
1. Automatic Dual Power Switching
The ATS automatically detects the status of the main power supply. When power failure, voltage abnormality, or phase loss occurs, it switches to the backup power source automatically.
When the main power returns to normal, the system can automatically transfer back to the primary supply.
Benefits:
- Ensures uninterrupted power availability
- Reduces manual operation
- Protects sensitive electrical equipment
2. Fast Transfer Response
With a rapid switching response time, the ATS minimizes power interruption during source transfer.
Transfer time: <100ms
This makes it suitable for applications requiring stable power continuity, including:
- Security systems
- Communication equipment
- Data equipment
- Medical devices
- Emergency lighting systems
3. Compact DIN Rail Mounting Design
The modular design allows easy installation inside standard distribution boxes and electrical cabinets.
Advantages:
- Space-saving structure
- Easy installation and maintenance
- Compatible with standard DIN rail systems
- Suitable for residential and commercial distribution panels
4. Manual and Automatic Operation Mode
The integrated Auto/Manual selector switch allows users to choose between automatic operation and manual control.
Automatic Mode:
- The device monitors power conditions and switches automatically.
Manual Mode:
- Users can manually control the switching status during maintenance or testing.
5. LED Status Indicators
Built-in LED indicators provide clear information about operating status.
Indicator functions include:
- Power source status
- Load operation status
- Switching position indication
Users can quickly identify the working condition without additional testing equipment.
