UNIVERSAL免维护蓄电池UB12220 12V22AH
usage precautions
SLA batteries, if used under recommended conditions, generate no sulfuric acid gasses. However, because they contain lead and sulfuric acid, which are both toxic, proper care and handling is important in order to avoid accidental fires, damage to property, bodily injuries or even death. > Improper charging and poor maintenance may cause battery to emit hydrogen gas; therefore, do not use battery near a spark,fuse, flame and/or equipment that emits sparks. > Never mix the SLA batteries together with other types of batteries, such as dry cells and nickel-cadmium batteries. > Keep the battery terminals from contract with wire, metal
cabinets, metal tools, such as screw drivers, spanners, torque wrenches unless they are properly insulated. Do not wear any watches, personal jewelry, hair pins or any other metallic objects when servicing the batteries. > Short circuiting the terminals of the battery can cause burns, injuries, damage to the storage battery, or trigger explosions. > Do not direct solder to terminal. This may lead to electrolyte leakage. > Do not use SLA batteries in the upside down position. > Do not use organic solvent, cleaning agents, paint/thinner, petroleum products to clean battery surface. These products can lead to battery container/cover cracking. > SLA batteries may not be compatible with certain equipment. Any uncertainty about the specifications of the battery should be brought to our attention. > Observe circuit polarities. Do not make or break live circuits. > As appropriate, use an insulating blanket to cover exposed portions of the battery system when performing extended maintenance that could result in personal or equipment contact with energized conductors.
使用注意事项
SLA电池,如果在推荐的条件下使用,不会产生硫酸气体。然而,由于它们含有铅和硫酸,它们都是有毒的,适当的处理和保养是很重要的。 为了避免意外火灾、财产损失、人身伤害甚至死亡。充电不当和维护不善可能导致电池排放氢气,因此不要使用电池。 在火花、熔断器、火焰和/或发射火花的设备附近。不要将SLA电池与其他类型的电池(如干电池和镍镉电池)混在一起。>保留电池 与电线,金属柜,金属工具,如螺丝刀,扳手,扭矩扳手签订合同,除非它们是适当绝缘的。请勿佩戴手表、个人珠宝、发夹。 或任何其他金属物体在维修电池时。电池端子短路会引起烧伤、受伤、蓄电池损坏或引发爆炸。不要乱来 将焊料焊至端子。这可能导致电解质泄漏。不要在颠倒位置使用SLA电池。不使用有机溶剂,清洗剂,油漆/稀释剂,石油产品 清理电池表面。这些产品会导致电池容器/外壳开裂。SLA电池可能与某些设备不兼容。关于蝙蝠规格的任何不确定性 应该引起我们的注意。>观察电路极性。不要制造或破坏活电路。>酌情使用绝缘毯覆盖电池系统暴露的部分 执行可能导致个人或设备与带电导体接触的延长维护。
1、额定输出电压:在规定的输入直流电压允许的波动范围内,它表示逆变器应能输出的额定电压值。对输出额定电压值的稳定准确度一般有如下规定:在稳态运行时,电压波动范围应有一个限定,例如其偏差不超过额定值的±3%或±5%。在负载突变或有其他干扰因素影响的动态情况下,其输出电压偏差不应超过额定值的±8%或±10%。
2、输出电压的不平衡度:在正常工作条件下,逆变器输出的三相电压不平衡度(逆序分量对正序分量之比)应不超过一个规定值,一般以%表示,如5%或8%。
3、输出电压的波形失真度:当逆变器输出电压为正弦度时,应规定允许的最大波形失真度(或谐波含量)。通常以输出电压的总波形失真度表示,其值不应超过5%(单相输出允许10%)。
4、额定输出频率逆变器输出交流电压的频率应是一个相对稳定的值,通常为工频50Hz。正常工作条件下其偏差应在±1%以内。
5、负载功率因数:表征逆变器带感性负载或容性负载的能力。在正弦波条件下,负载功率因数为0.7~0.9(滞后),额定值为0.9。
