Ensure uninterrupted power supply with our Dual Power Automatic Transfer Switch (ATS). Designed for residential and light commercial applications, this compact switch automatically transfers the load between two power sources, providing seamless backup power during outages. Its miniaturized design fits standard distribution panels, making it an ideal solution for home backup generators, solar systems, and critical circuits.
Key Benefits
- Automatic Power Transfer: Instantly switches to backup power when the primary source fails, ensuring continuous operation of essential appliances.
- Versatile Compatibility: Available in 2P (single-phase) and 3P/4P (three-phase) configurations, supporting 220V and 380V systems.
- Compact & Easy Installation: Mini household design saves space and simplifies wiring in standard electrical panels.
- Reliable Performance: High-quality contacts and mechanisms ensure long service life and minimal maintenance.
- Safety Certified: Meets international standards for electrical safety and reliability.
Applications
- Home backup power systems with generators
- Solar PV systems with battery storage
- Small commercial buildings and shops
- Critical circuits requiring uninterrupted power (e.g., security systems, refrigeration)
Why Choose Our ATS?
Our Dual Power Automatic Transfer Switch is engineered for durability and precision. The 2P model handles single-phase 220V loads, while the 3P and 4P models support three-phase 380V systems with four-wire configurations. The switch's intelligent control module monitors both power sources and activates the transfer within milliseconds, preventing data loss and equipment damage. Its flame-retardant housing and silver alloy contacts ensure safe, efficient operation even under high loads. Whether you're upgrading a residential panel or outfitting a small business, this ATS delivers dependable performance at an affordable price.
Installation & Maintenance
Installation is straightforward: mount the switch on a standard DIN rail, connect the primary and backup power lines, and wire the load output. The unit requires no external control wiring, reducing installation time and cost. Regular inspection of connections is recommended to maintain optimal performance. Backed by our quality guarantee, this ATS is a smart investment for energy resilience.
