Uninterruptible Power Supply 10U 36KW 48VDC Rectifier System Switch Mode For Telecom Backup

 

1. 10U 33KW 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:

of 3000m to 4000m,the maximum operating

temperature decreases by 1℃ as the altitude increases by 200m)

 

 

Product Feature

 

1) The rectifier module adopts active power factor compensation technology, and the power factor value reaches 0.99.

2) The normal working range of AC input voltage is wide to 90~290V, Single Phase, (323V~480V ac, 3 Phase).

3) The rectifier module adopts full-bridge soft-switching technology, and the efficiency is up to 96%.

4) Smart battery management. There are load power-off and battery low-voltage protection (LVLD+LVBD) and secondary power-off (secondary power switch) functions, which can realize functions such as temperature compensation, automatic equalization and floating charge control, automatic voltage regulation, battery capacity calculation, and online battery testing.

5) The rectifier module adopts non-damage hot-swappable technology, plug and play, and the replacement time is less than 1min.

6) Networked design, providing multiple communication interfaces (such as RS485, dry contact), flexible networking, real-limited local and remote monitoring, unattended.

7) Lightning protection design for AC and DC sides, suitable for thunderstorm areas.

8) Support fault protection and fault alarm functions.

9) Friendly operation and maintenance can be installed against the wall, effectively saving space.

10) Ultra low radiation. Adopt advanced electromagnetic compatibility design.
