Packing list 1 * Dual-power Automatic Transfer Switch 2 * Protective Cover 1 * Accessories 1 * Instruction Manual Precautions 1. Ambient temperature must not exceed 40°C nor fall below -5°C, with an average temperature not exceeding 35°C over 24 hours. 2. Installation altitude should not exceed 2000m. 3. At maximum temperature (40°C), relative humidity at the installation site should not exceed 50%. At minimum temperature (-5°C), higher relative humidity may occur (e.g., 90% RH at 25°C). Special measures should be taken to address occasional condensation on the product surface due to temperature variations.

• [35mm DIN Rail Mounting] - This dual-power automatic switch is a miniature household power switch primarily used to test whether the main or backup power source is functioning normally, ensuring power continuity.
• [Premium Materials] - Our Brushless ESC Constructed from high-quality PC flame-retardant plastic, offering excellent insulation, high-temperature resistance, and anti-aging properties for safe and reliable operation.
• [Dual Operation Modes] - Supports both automatic and manual operation with millisecond switching without power interruption. Compact design ensures reliable transmission and facilitates easy installation and maintenance.
• [Millisecond Level Switching] -When the normal power source malfunctions, the backup power source activates immediately. Millisecond-level switching achieves uninterrupted power supply, ensuring continuity, reliability, and safety.
• [Wide Application] - Switches to backup power during outages and reverts to main power upon restoration. Suitable for 50/60Hz AC rated 220V emergency power systems, widely used in facilities requiring uninterrupted power supply.
