2P 63A 220V ATS Dual Power Automatic Transfer Switch 2 Position Dual Power Emergency Power Photovoltaic Switch for Home and Industrial Systems

【Dual Switching Mode】 The power transfer switch is located at the PC level. The automatic mode is used in case of power interruption, while the manual mode is used for direct control. The switching time between the main power supply and the backup power supply is 0.05 seconds, which reduces the risk of device restart and meets all your power needs. 【Easy to Install and Use】 The dual power automatic transfer switch uses a 35mm DIN rail. It can be installed vertically or horizontally in PZ30 cabinets and other distribution boards. Its extremely compact design effectively reduces construction costs. 【Complete Safety】 The backup power transfer switch is made of ABS and uses silver alloy contacts, providing fire and dust protection, strong electrical conductivity of the contact, and good insulation. It complies with IP30 enclosure protection rating, CE/UL and other standards. Multiple safety certifications; it also has a surge protection function, 220V / 50Hz Undervoltage value: 175V Recovery value: 195V Overvoltage value: 260V Recovery value: 240V (± 5V), the surge value can be customized 【Worry-free scene application】 2P is a single-phase circuit with an operating voltage of 220V (85% -110%); 4P is a three-phase circuit with an operating voltage of 380V (85% -110%). 2P is mainly used for power supply to small loads such as homes, offices and others, while 4P is suitable for power supply to industries, commerce and large buildings. 4P offers more stable performance and higher efficiency than 2P and is ideal for driving large motors and other heavy equipment.
