Product Information

About this item

• It mainly used for automatic or manual conversion of two power supplies,and can test whether the common power supply or backup power supply is normal.Both power supply A and power supply B can be connected to the mains/generator/photovoltaic.
• 【110V Over-Voltage and Under-Voltage Protection】110V/50Hz Undervoltage value:85V,Recovery value:95V;Overvoltage value:145V,Recovery value:130V(± 5V).【220V over-voltage and under-voltage protection】220V/50Hz Undervoltage value:175V,Recovery value:195V;Overvoltage value:260V,Recovery value:240V(± 5V).
• When the normal power is abnormal,the spare power works at once,which therefore ensures the continuirty,reliability,and safety of power supply.It does not guarantee completely uninterrupted,but minimizing issues from power interruptions.When the normal power supply is normal,it will automatically switch back from the backup power to the normal power supply.
• Suitable for scenarios that cannot tolerate power outages,such as hospitals,low-temperature cold storage,data centers,and other high-demand situations.When the main power supply fails,it can automatically and quickly switch to the backup power supply to ensure the safety and reliability of the electricity supply.
• Both are equipped with indicator lights.In automatic mode,when the normal power supply A is working properly,A(red light)is on;when the normal power supply A is abnormal,A(green light)goes off.In manual mode,if power supply A is selected,operating the red handle on the right towards power supply A will turn on the red light for A.If power supply B is selected,manually operating the red handle on the right to switch towards power supply B will turn on the red light for B.
