The ASIA TOP ATVP02-100A is an intelligent three-phase auto-selector and changeover switch designed to ensure a stable power supply for critical loads. It continuously monitors three separate voltage lines (L1, L2, L3) and automatically switches to a healthy phase if the current one fails or experiences voltage irregularities. This device is an essential safeguard for homes, factories, and generator-backed systems.
Key Features
-
Automatic Phase Switching:Â Seamlessly transitions between phases to maintain continuous power.
-
Comprehensive Monitoring:Â Real-time LED digital display for voltage across all three phases and current (Amps).
-
Built-in Protection:Â Offers robust voltage monitoring and protection against fluctuations.
-
Fully Adjustable: Features a programmable recovery time ranging from 1s to 500s to suit different equipment requirements.
-
Wide Operating Range: Compatible with a broad voltage spectrum from 140V to 300V.
