Monitor UPS power capacity installed in the calculation of
How to determine what type of UPS you need power? Typically, personal office and home users to consider back-up models, such as the Hills-line UPS power low-cost, thin, light and is an ideal PC partner. Has a very high price; system for small and medium sized network users, servers, or precision instruments, the multi-line or line interactive UPS power supply, can better resist the power line from a variety of violations, its functional and Most intelligent monitoring and network connectivity, remote control and intelligent management. Important for large-scale equipment and systems, high-power Hills-line UPS power protection essential to provide a stable power supply. Specifically how to determine the required power (VA) size? Need to list all the equipment need to be protected, do not forget to display terminals, external hard drives. Voltage and current of each device on the backplane data can be found by multiplying the two can get VA. Some devices require electrical energy in watts that, you can see the tile was roughly 1.4 times the number of VA. For the whole device is its rated power as the base number. The aggregate value of all the VA facilities, will be aggregated value plus 30 percent expansion of capacity to prepare for the system upgrade with.
How to configure back-up delay time? Because different systems and equipment, select and configure the UPS power supply models are also different. UPS power supply standards of the machine itself comes with UPS batteries in general will continue to supply power after a few minutes to a few minutes; and long-acting UPS power supply with external battery pack, users can continue to supply extended power outage need to reserve time can be designed to ten minutes when the number of hours or longer. General long-acting UPS Power UPS battery backup time is mainly affected by the cost of installation space and battery recharge time and other factors. Generally the less electricity, power outages are more frequent in areas with a UPS power and generator power mode. When a power failure, UPS battery power first by a period of time, such as the outage time is longer, you can start the backup generator to supply power to the UPS, when electricity is restored and then switch to the mains supply. Battery life is mainly affected by the load size, battery capacity, temperature, battery discharge cutoff voltage and other factors. According to delay the ability to determine the size of the battery capacity required, with the security value to indicate when the AH to a given current amperage discharge time when the number of hours to calculate. UPS configuration to look at the general formula: UPS Power (VA) x delay (hours) / UPS battery power required to start the DC = Ann hours (AH) to Hills C3KS delay 4 hours, for example we calculate Next:: (Note: Hills C3KS to start DC: 96V) 3000 VA x 4 hours / 96V = 125AH 125AH battery results are needed to meet the four-hour power supply, but generally do not have regular UPS battery's capacity 125AH a group of eight (because C3KS start DC is 96V-(UPS standard at the factory DC), normally most of 12V DC battery, 96V (UPS startup DC) / 12V (Battery voltage) = 8, so in order to 8 batteries for a group) UPS batteries.
We can choose a 100AH battery to configure it; the delay time: 100AH (UPS battery capacity) x 96V (UPS startup DC) / 3000V (UPS Power) = 3.2 hours can also choose to group 2 (16 ) 65AH batteries of UPS in parallel configuration! the delay time: 65AH x 2 x 96V / 3000VA = 4.16 hours U.S. Hills UPS power supply voltage standard at the factory start DC: MT1000SC1KS C2KS-C3KS C6KS-3C20KS 3C3-10KS - 3C340KS 24VA 36V 96V 240V 384V U.S. Hills UPS power supply voltage output power factor are 0.7; such as Hills C1KS maximum support load power: 1000V x 0.7 = 700W, so the Hills C1K maximum support loading of 700W, and so on !! (Note: In order to make better use of the general UPS power supply, UPS power supply is best not to recommend no load / full load or overload use, UPS power supply load power is the best of its standard load of 70% -80%, such as C1K with the best load for the 500-600 (w) of the load! this UPS power supply can better play its characteristics and advantages of the power to extend the service life of UPS!
Fujian Quanzhou: private enterprises have entered the "low-carbon road"
Post-crisis era, Quanzhou, Fujian Province private enterprises or industries to switch to low carbon or low carbon technology to transform traditional industries, a surge of low-carbon boom is surging.
Quanzhou factors known to well-developed private economy at home and abroad. It is understood that a total of 36 000 private enterprises in Quanzhou, Quanzhou, active in private funds, the total number of no less than 200 billion yuan.
For the headquarters in the town of Jinjiang Cizao Huatai Group pioneered the world's first ceramic block of solar power panels at the Shanghai World Expo will be a debut, it has attracted global attention of many buyers, the current product demand, the company is at full capacity.
Fujian Fujian is the Everest Group, the largest cotton spinning company in the cotton products business for many years after the last adjustment, determined to enter the new low-carbon production of bamboo fiber fabric. Chen, general manager of pine trees, at present, bamboo fiber products are very popular, Everest Group's production capacity will be expanded next year to 5,000 tons, three years to reach 1.5 million tons. Low-carbon bamboo fiber textile products, profit margins remain high at above 20%.
Optoelectronic information industry base in Quanzhou, has gathered a number of private high-tech companies, mostly high-end carbon-based industries. Three crystal is very representative of a company. This private enterprise, a change in the past, only the production of polysilicon materials development model, determined to enter the solar cell R & D, in March last year, three crystal company successfully developed the physical method of solar cells, has entered mass production.
Quanzhou Bureau of Statistics, said analysts, this year, the national policy-intensive control the property market, coupled with the capital market downturn, some of the private capital began to flow to the real economy continued, in which the emerging low-carbon industry is one of the main directions.
