1. Product Introduction of 48V Communication Power Supply System
High-performance and high-reliability power supply product-48V communication power system, input: 90～290Vac; output: 42～58Vdc; suitable for small program control switches, access networks, transmission equipment, mobile communications, satellite communications ground stations, microwave communications power supply, It can also be used to power other communication equipment. Under normal circumstances, various parameters of the rectifier module and power distribution unit are controlled by the monitoring module, and work according to their predetermined parameters or user commands. If the mains fails, the system will be powered by the battery at this time.
As the battery discharges, the battery terminal voltage begins to drop. When the battery voltage is lower than the 46V upper computer (settable) battery low-voltage alarm point, the monitoring module reports an alarm. Signal, directly close the load output, the whole machine does not work. When the external mains power is restored, the system returns to its normal working state (the above monitoring data is the default value of the system, and the user can reset it). If the working environment temperature is ≥55℃, the power supply system will need to reduce the power output.
