Smart Wi-Fi 125A Din Rail 2P ATS Dual Power Automatic Transfer Switch Electrical Selector Uninterrupted Power 230V

TOMZN Din Rail WiFi Smart ATS Timer – 230V Dual Power Automatic Transfer Switch (2P 125A) with eWeLink

Seamless Automatic Power Switching for Uninterrupted Supply

The TOMZN Din Rail WiFi Smart ATS Timer is a high-capacity 2P 125A automatic transfer switch designed to automatically switch between two power sources without manual intervention. Ideal for homes, offices, shops, server rooms, and industrial setups, this device ensures continuous power by transferring supply instantly from the primary source to a backup source whenever a power failure is detected.

Perfect for inverter systems, generators, grid-to-solar setups, and hybrid energy installations.

Dual Power Intelligent Automatic Transfer (ATS)

This smart ATS continuously monitors two independent 230V power inputs (Source A and Source B). When the main power fails or falls outside preset voltage parameters, the switch automatically transfers the load to the backup power source. Once the primary supply is restored and stable, it reverts back automatically.

• Automatic transfer between two power sources
• Real-time voltage detection
• Stable and reliable switching logic
• Designed for uninterrupted power supply
