The CH0004 is a self-contained Battery Charger/conditioner
mounted in a ruggedized environmentally resistant case, which provides a
reliable and consistent recharge of one or two batteries simultaneously. The
CH0004 auto senses battery type to assure proper charge profile.
Unattended Charging
• Smart charge modules that detect open or shorted
cells. If a defective cell is detected the CH0004 will not start charge cycle
• No programming or special instruction set
to achieve safe and complete recharge of battery
• In no event will a battery be overcharged
using the smart charging
techniques of the CH0004
Wide Range
Input Voltage
• Allows operation from nearly any AC or DC
power source likely to be encountered worldwide
Conditioning
Cycle
• Automatic discharge/recharge function
included. The conditioning cycle can be activated individually per battery at
operator`s option
Recharge
Each String of Cells
• To assure a positive recharge of the
battery each individual string of cells in the battery is recharged
independently
Any combination
of the following batteries: BB-390/U - (NiMH), BB-590/U - (NiCd), BB-2590 /
UBI-2590 (UBBL02) / MRC-2590 /UBBL09 / UBI-2590 SMBus (UBBL10) -Lithium-Ion

At the conference on the promotion of LED lighting in the public lighting field in Guangdong Province held at the end of May 2012, the provincial government and local governments signed a letter of responsibility for the promotion and application of LED lighting products in Guangdong Province. One of its most important tasks is to plan the Pearl River Delta region to strive to popularize LED public lighting before the end of 2014 by the end of 2013, and then drive the whole society to popularize LED lighting to achieve energy saving under the province's year-on-year caliber. %the above.
Since the signs of recovery in the second quarter of 2013, the overall development trend of the LED lighting market has continued to improve, especially the commercial lighting market that gradually accelerates the application of LED lighting products. The LED outdoor functional lighting market, which is mainly driven by LED street lights, is growing rapidly.
According to the latest research data of the High-tech LED Industry Research Institute (GLII), the scale of China's LED outdoor functional lighting market reached 12.1 billion yuan in 2013, a year-on-year increase of 47%. In 2013, China's LED street lamp shipments exceeded 2.5 million ç›, LED street lights. The market scale exceeds 6 billion yuan, and the growth rate is close to 50%.
LED street lights, commercial photos and outdoor landscape lighting have accelerated the LED lighting market, while the competition among downstream LED companies has become increasingly fierce. The most obvious trend is that the differentiation trend among enterprises is becoming more and more obvious, and the orders and winning projects are concentrated to listed companies and large-scale enterprises.
Judging from the announcement of the domestic bidding in 2013, the government LED street lamp energy-saving renovation bidding project was basically by Qinshang Optoelectronics (002638.SZ), Zhouming Technology (300232.SZ), Hongli Optoelectronics (300219.SZ) Lehman Optoelectronics ( 300162.SZ) and Lianchuang Optoelectronics (600363.SH) and other LED listed companies involved in the downstream.
An industry insider said that in addition to the high requirements for LED streetlight performance, light efficiency and longevity of the bid-winning project, most streetlight energy-saving retrofit projects use the EMC (contract energy management) model, requiring companies to advance funds, and listed companies in this regard. It is more advantageous and therefore benefits a lot.
Taking Qinshang Optoelectronics as an example, the Shanghai-Nanjing high-speed LED lighting project won the bid in 2013, the Guangdong Yingde LED streetlight renovation project with a total purchase amount of approximately 18.162 million yuan, the 50.8 million yuan Nanhai Shishan Town LED streetlight renovation project and the Guangzhou Metro demonstration The EMC model is adopted for engineering projects, and the duration of government affairs is generally around 7 to 8 years. If there is no strong capital chain as a support, the average small and medium-sized LED companies may not be able to match.
Although it is at a disadvantage in terms of capital and scale, this does not mean that small and medium-sized LED companies have no place in the field of government engineering lighting.
“Many local governments generally have local protection for local engineering bidding. As long as the quality and light performance of small and medium-sized LED enterprises meet the requirements of tenders, the chances of winning the bid or getting government orders are still high.†LED in South China The vice president of the street lamp company told reporters that if the relationship with the local government is well handled, small and medium-sized enterprises still have their way of survival. 
Public lighting orders to concentrate on LED companies to survive
[Text / Reporter Wang Cairong] At the beginning of 2014, it was less than one year since the deployment of Guangdong Province to complete the task of fully popularizing LED public lighting by the end of this year.
