DESCRIPTION
Specifications
The AST dual power supply box (cabinet) is a product designed by our company according to the actual power distribution requirements and corresponding requirements. It can automatically switch between power grid and power generator, and between power grid and power grid. In the process of transfer between power grid and power generator, power generation start delay and generator idling delay signal are added, so as to automatically start the generator when the power grid is cut off unexpectedly. When the grid is renovated, it automatically switches to the grid and shuts down the generator simultaneously. It is also integrated with leakage protection, over-current, over-voltage, lack of phase protection, with small volume, high protection grade, perfect protection performance, high degree of automation and many other benefits. For the special consideration of updated fire protection requirements of dual power box (cabinet), PC class dual-power automatic transfer switch and single magnetic circuit breaker are selected to meet the fire fighting requirements of overload without tripping, to ensure the normal operation of fire fighting equipment. It is the optimum power supply and distribution facility in hotels, schools, hospitals, stations, theaters, commercial and residential buildings, scientific research institutions, industrial and mining enterprises, civil skyscrapers etc.
This product adheres to the IEC61439 standard and GB7251-95 "Low-voltage switchgear and controlgear assemblies".
