- Automatic load transfer for uninterrupted power: When the main power supply fails, it automatically re-routes one or more load circuits from the failed supply to a standby supply to keep the load powered. It can switch between the main and standby power supplies with a transition time of about 2 seconds. - High safety and reliability: Built with a high quality motor and protective cover, and CE certified for professional safety and reliability. - Manual and automatic operation: Includes both manual and automatic modes. The color coded toggle switch is set to the left position for automatic mode and to the right for manual mode to meet different requirements. - Stable, quiet operation: Uses a pure copper motor to ensure stable operation and minimize noise, so it does not disturb normal activity. Performance remains reliable under both high and low temperatures. - Practical use scenarios: 1) In data centers or server rooms to protect critical servers, network equipment, and storage from power outages. 2) In home or office environments to safeguard computers, routers, and NAS devices during power interruptions. 3) In industrial or laboratory settings to maintain continuous operation of essential machines and instruments.
