DC48V 450A Backup Power Supply System 19-Inch 6U Standard Rectifier Power Telecommunication Cabinet
Backup power supply system for 19-inch standard rectifier power telecommunication cabinet
1. 6U 27KW Rectifier System
The "48VDC Rectifier System" typically refers to a direct current (DC) power system that outputs 48 volts (VDC). Such systems are commonly used in telecommunications,
data centers, industrial control, and other applications requiring stable DC power.
The rectifier, the key component of this system, primarily functions to convert alternating current (AC) electricity into direct current (DC) electricity.
ET48450 consists of distribution unit, rectifier module, conversion module, monitoring module. The standard as table below:

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.
