Uninterruptible Power Supply 10U 36KW 48VDC Rectifier System Switch Mode For Telecom Backup
1. 10U 36KW Rectifier System
A Rectifier system converts alternating current (AC) to direct current (DC) and provides the power necessary to charge batteries. With a focus on continuously improving the total cost of ownership, ESTEL’s rectifiers, combined with advanced control and monitoring features, help to reduce both capital and operational expenditure. Our rectifier systems boast excellent power density while fulfilling space and weight requirements. They leave plenty of room for other equipment and create savings in packaging and transportation costs. In addition, their high efficiency lowers total energy consumption and reduces carbon footprint.
The embedded communication power supply system (Rectifier System) is suitable for small program-controlled switches, access networks, transmission equipment, mobile communications, satellite communications ground stations, microwave communications power supply, and can also be used for power supply for other communications 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 dc (Alarm Value can be settable) battery low-voltage alarm point from monitor, 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 resumes normal operation.
ET48600 consists of distribution unit, rectifier module, conversion module, monitoring module. The standard as table below:
