ATS-1 Dual Power Distribution Box
Short Description:
The backup power supply is usually supplied from a diesel generator. During operation, a controller is used to switch between main and backup power supply: when the main power supply is powered, the controller automatically closes the main power supply circuit, relying on a transformer for power supply;
Product details
As the name suggests, a dual power distribution box has two power supply lines and is generally used for low-voltage distribution boxes;
The main power supply is usually mains power, which comes from a transformer;
The backup power supply is usually supplied from a diesel generator. During operation, a controller is used to switch between main and backup power supply: when the main power supply is powered, the controller automatically closes the main power supply circuit, relying on a transformer for power supply;
When the main power supply loses power, the controller will send a start signal to the generator set to power the engine. At this time, the backup power supply circuit will be energized, and the dual power supply will automatically separate the main power supply and close the backup power supply;
When the main power supply is restored, the backup power supply will be separated and the main power supply will be closed. The controller will then send a signal to the generator set to stop it;
In fact, this is what we usually refer to as the "self switching and self restoring" function of dual power supplies;
Ordinary low-voltage distribution boxes are generally divided into incoming cabinets, capacitor compensation cabinets, and feeder cabinets. They all have only one power source from the transformer, no backup power source, and cannot switch power sources.
