220V Dual Power Automatic Transfer Switch Module 10A

The 220V Dual Power Automatic Transfer Switch Module is an intelligent, high-speed switching board designed to automatically toggle between a primary and a backup AC power source. Supporting up to 10A of load current at 220V AC, this module ensures uninterrupted power to your critical appliances, DIY UPS setups, and smart home automation projects. When the primary power source fails, the onboard sensing circuitry instantly switches the output to the backup source, minimizing downtime and protecting sensitive electronics.

This module is highly popular among makers and engineers for building reliable backup power systems, server rack power redundancy, and automated test benches. It features robust screw terminals for secure high-voltage wiring and is fully compatible with standard Indian domestic mains voltage (220V-240V AC). The dual-relay design provides physical isolation between the two input sources, preventing backfeeding and ensuring safe operation.

Features:

• Dual AC Inputs: Seamlessly switches between primary and backup 220V AC power lines.
• High Load Capacity: Equipped with high-quality Songle relays capable of handling up to 10A resistive loads.
• Fast Switching Speed: Rapid transition time ensures minimal interruption to connected devices.
• Physical Isolation: Dual-relay configuration prevents cross-connection or backfeeding between the two input sources.
• Onboard LED Indicators: Provides clear visual status of the active power source.
• Robust Screw Terminals: Heavy-duty terminal blocks ensure secure and reliable high-voltage connections.
