Hawk battery NP38-12 Tel; 01058486362 Product Description Model / Specifications NP38-12 brand / trademark British Hawk battery .3 631.0 60.0 20.0 68.0 20.0 1.00 data center industry has developed rapidly in recent years??????? equipment bearing pressure data center room to grow, the number of high-frequency switching power supplies, uninterruptible power supplies and other power equipment also will be increased dramatically, so that the battery has been widely used in data center applications the battery is very popular. Battery trends 1UPS system 6, maintenance-free batteries due to electrolyte absorption system, in normal use does not produce any gas, but if you used improperly, causing the battery overcharge, will produce gas, when the battery internal pressure will increase the pressure on the valve will open the top battery, a serious cause battery burst. Data center operations require almost year round operation, disruption of network equipment power means that the business and economic losses due to the UPS power supply equipment is expensive, it is impossible for the data center all the devices are equipped with UPS power supply, which often unexpected power outages will cause losses to the data center. 6, maintenance-free batteries due to electrolyte absorption system, in normal use does not produce any gas, but if you used improperly, causing the battery overcharge, will produce gas, then pressure will increase the battery will The pressure of the battery on top of the valve opening, a serious cause battery burst. Hawk battery NP75-12 / 12V75AH Changchun's role is to replace the battery: When the mains fails, the engine has started and within the switching time support UPS power to the load. However, since the starting time of diesel generators is generally within 10 ~ 15s, while the grid to the oil-switching time is just a few hundred milliseconds, so the battery backup power for a short time, but considering the battery capacity utilization rate high-current discharge Therefore, backup power time 5 ~ 15min sufficient. Continue to increase the data center, to promote the positive growth UPS market, which of course also includes batteries. However, due to the construction costs continue to push for the need to occupy a lot of space in the back-up power supply, the use of high-power batteries can reduce the number of batteries used in order to save even more space. In addition, the performance of the battery when the power increase, then the power of the unit price will be significantly reduced, reducing battery procurement costs. 2) Power-on Security: UPS in the first boot, fingers in the press should not leave the power on switch when the switch immediately, but the case focused start the machine, if there is abnormal noise, burning and other unpleasant odors or smoke the machine should be turned off immediately. Note: To close the door when you turn on or shut to prevent unexpected burst of electrolytic capacitors and other components of the next-generation green data center and injured will strive to achieve "energy saving, green carbon", and vigorously promote low-carbon life-cycle operations! The idea of ??covering the planning and design, equipment and materials selection, construction and implementation, operation and maintenance management of all aspects, from the technical and managerial comprehensive energy conservation and emission reduction. Therefore, the DC 380V, 80kVA UPS systems, backup power time of 15min, should select a group of 32 12VHRL-400 battery can. (D) re-combined market power increase with load after the mains / inverter to run the test with a normal load conditions; Hawk battery NP75-12 / 12V75AH Changchun replace the British Hawker Battery Group as early as 1891 began production all kinds of batteries, one of the earliest battery manufacturers in the world. After more than a century of development, it has become an authority in Europe and the world of industrial batteries. 2002 Hawker Battery Group into the United States Enersys Group, the world's largest supplier of industrial batteries. Enersys offices all over the world, is located in Shenzhen's office to provide the most direct, most professional service for Chinese users. [1] The advantages of the active substance formulations to optimize battery, the battery capacity is higher than DIN40742 standards;??, The largest single capacity 3170AH, avoiding the loss of capacity and imbalances caused by batteries in parallel;?, Gas recombination rate of more than 98%, without battery add water, low maintenance;?, very low self-discharge rate, stored for 2 years without supplementary charge;?, cycle life of more than 1200 times 80% DOD;?, can quickly return charge, maximum charge current is 40 0;??, no mist escapes during normal use, the battery can be installed in offices or main equipment room;?, easy to install, according to the site space and bearing arrangement of horizontal or vertical installation [2]
