1. Brief introduction

Power Express is a high-tech product, rst developed successfully by Shuangdeng Group Co., Ltd (Oversea Brand "Shoto") in China. It has many features such as integration, miniaturization, light-duty , convenience , energy conservation and environmental protection etc. The product is widely used in remote access equipment, mobile communication equipment, transmission equipment, satellite ground stations and microwave communications equipment, and other areas of the communication as an emergency backup power supply.

The product adopt the AC power supply emergency access way with online access without interruption. And it also equip with the standard interfaces that are AC input, the AC and DC output .They can meet the demands of AC or DC load and backup power supply time in dierent applications. The product is designed by portable aluminum alloy rod box which is
of high strength, beautiful appearance, convenient handling. In addition, it can adapt the working condition at temperature from - 20 ℃ to + 50 ℃ ; The lithium iron phosphate battery not only has advantages like high specic energy, small volume, light weight, long cycle life, but also has the functions such as battery pack overcharge and discharge protection, over current, short circuit protection, over temperature protection, monomer battery overcharge and discharge protection, etc.

2. Production advantage

1.No noise, no pollution, environmental protection and easy moving thus can be used instead of diesel generator in the eld of energy storage;

2.The product equip with parallel line and output line and use special connector to prevent reverse, support increase capacity in parallel connection,and it can replace the traditional wiring, more safety and conveniently;

3.The product adopt integrated operation panel design, all operations can be conducted on the panel, more conveniently and eective;

4.Great heat dissipation performance, and it has ventilation holes on the bottom of box and on the panel;

5.The product has management system, it can improve the eciency of battery, it also has the RS232 and RS485 communication interface, supporting communication and remote monitoring to realize the unattended.
