What is a dual power switch? The dual power switch is a switch that automatically switches to another power supply due to power failure. General dual power switch is widely used in communities, hospitals, airports, terminals, chemicals, and other important places that do not allow power outages. Let me briefly introduce the dual power switch for everyone.
What is a dual power transfer switch
An appliance that consists of one or more switch-switching appliances and other necessary appliances for detecting power circuits and automatically switching one (or more) load circuits from one power source to another.
Composition of dual power switch
ATSE generally consists of two parts: the switch body + controller. The switch body is divided into PC grade (integral type) and CB grade (circuit breaker).
PC grade: ATSE that can be turned on, carried, but not used to break the short circuit current. The main body is a load (isolation) switch, which is an electromechanical switchgear. The conversion mechanism is driven by a motor or an excitation.
Class CB: ATSE with overcurrent release, its main contacts can be switched on and used for breaking short-circuit current. The circuit breaker (miniature circuit breaker or molded case circuit breaker) is equipped with a mechanical interlock device. The controller is mainly used to detect the working status of the monitored power supply (two channels). When the monitored power supply is faulty (such as any phase failure, undervoltage, voltage loss, or frequency deviation), the controller issues an action command. The body automatically carries a load from one power source to another.
Dual power switch usage
The dual power transfer switch is a widely used power conversion device. When a common power supply experiences a loss of voltage, undervoltage, overvoltage, or lack of equal failure, it can quickly and automatically switch the load from a common power source to a backup power source, thereby ensuring the continuity and reliability of power usage.
Dual power switch classification
Dual power automatic transfer switch: automatic, electric and manual operation
Dual power electric switch: can be operated electrically and manually
Dual power manual transfer switch: manual operation (by handle and shaft)
Dual power switch brand recommendation

Editor's summary: The above is about the introduction of the dual power transfer switch , each place lacks this dual power transfer switch will not be able to operate, at least in the power of this piece will be very strenuous. If you need to buy, you may wish to consider the above several brands, I believe there is always a suitable for you.
