ZTE ZXDU68B301 embedded power system adopts embedded installation design, which is suitable for standard 19-inch cabinet installation. Nominal output voltage: -48V, nominal output current: 300A. The system can adapt to a wide range of AC input, and has the functions of intelligent battery management and remote environmental monitoring.
Product features
Power supply technology and computer technology are organically combined to monitor and control various parameters and states of rectifier and AC/DC distribution in real time.
Three-phase AC voltage input is adopted, which has a very wide input voltage range and is suitable for areas with unstable power.
Flexible configuration, more than 6 48V5OA switching rectifiers can be configured. Switch rectifier has hot-swap function.
With automatic battery management function. The monitoring unit automatically measures the charging and discharging current of the battery, and can control the system to float/uniformly charge the battery.
Provide secondary power-down function. When the system is switched to battery power supply, there will be audible and visual alarm after the battery voltage is too low.
According to the importance of the load, the load is divided into two groups, and the important load has a longer working time.
The system adopts multilevel lightning protection technology. Configure heat exchanger, battery heating board (optional configuration) and environmental monitoring board (optional configuration), so that the system has strong adaptability to the field environment.
The system has high reliability, with MTBF≥ h.
Simple structure, dust-proof, waterproof, heat-insulating, burglarproof, moisture-proof, mildew-proof, corrosion-proof and other functions, strong environmental adaptability, and can be used in outdoor harsh environments.
Drawer structure is adopted, which is convenient for transportation, installation and maintenance.
