Chapter 1 Overview

1.1 Brief Introduction

Emerson Network Power Co., Ltd focuses on power electronics and relevant control technologies. With broad range of products, it provides total power solutions to customers worldwide. The products include Telecom Power Systems, Board Mounted Power Supplies, Power & Dynamic Environment Monitoring Systems, UPS, Variable Speed Driver, Power Supply System, and VRLA Batteries etc.

The Emerson Telecom Front Access Series VRLA Battery is a reliable network power system based on the basis that meets the technical requirements for telecom and power supply application. Designed according to the telecom environment and other specific requirements, it provides an integrated power-supply solution, through integration with Emerson telecom power, to the user with the power need of the target equipment and battery DC power system fully considered.

1.2 Features

 Long Life: Up to twelve year design float life at 25℃.

 Standard Dimensions: Fit 19′and 23′cabinet

 High Energy Density: Volumetric energy density 96.9Wh/L, gravimetric energy density 34.3Wh/Kg.

 Safety Property: Using V0-Class flame retardant ABS container. The safety valve automatically regulates the battery internal pressure. The acid filter retains the acid fog, and serves as a flame arrestor to avoid the risk of explosion. The product is UL listed.

 High Reliability: The key parts and material such as safety valve, acid filter, sealing ring, sealing cover, separator and sealing material are all using import fittings with high quality to assure the high reliability of the battery.

 Low Internal Resistance: Using threaded copper insert terminal with good conductive performance, compact construction, and excellent discharge performance at high current.

 Low Self-discharge: Self-discharge is less than 3% per month.

 Perfect Deep-cycle Performance: Custom-made grid alloy and paste.

 Convenient Installation: Using front access, installation and maintenance are convenient.

1.3 Key Designs

1.3.1 Battery Grids

The alloy grids with four elements of lead, calcium, tin, and aluminium (alloy character is shown in the following figure) use special formulation. They provide high corrosion & extension resistance, together with great improvement of recharge ability after deep discharge, thus extending battery life and reliability. At the same time cathode hydrogen-separating over-potential is increased, and the hydrogen-separation is controlled effective at the end of the charge to keep the water of electrolytic not resolved.

1.3.2 Safety Valve

The safety valve can adjust inner pressure one-way and prevent the air outside from entering the battery. Thanks to about 99% oxygen recombination efficiency, the battery barely loses its electrolyte and requires no adding
