FBM201输入输出模块
是一种含有储能装置的不间断电源系统，将蓄电池（多为铅酸免维护蓄电池）与主机相连接，通过主机逆变器等模块电路将直流电转换成市电的系统设备。
断电往往是突发的，且较为频繁。UPS能够提供持续、稳定、不间断的电源供应，在市电出现异常时，有效地净化市电，在市电与负载之间，形成电能的“守护墙”。
UPS按应用场景可分成工业使用型工频机和机房数据中心使用型高频机两种。
FBM201输入输出模块工频机：
采用工频变压器作为逆变升压部件的UPS俗称工频机（对应国外的TRANSFORMER BASED UPS），主要由整流器、电池组、逆变器和升压变压器组成。工频机的主要特点是逆变器输出端有一个升压变压器，能把逆变器的输出电压升至380V，而其直流母线电压通常较低。
工频UPS多采用SCR可控硅整流器，常见的有6脉冲整流器和12脉冲整流器。为了提高输入功率因数、降低整流器对前级电网的谐波污染，需在输入端加入滤波装置，一般采用无源滤波器、有源滤波器或有源加无源混合型滤波器来解决工频机输入谐波较大的问题。
高频机：
利用高频开关技术，以BOOST直流升压电路将直流母线电压升至800V左右，从而替代逆变器输出侧工频变压器的UPS，俗称高频机（对应国外的TRANSFORMERLESS UPS），它主要由整流器、电池组、DC升压装置、逆变器组成。高频机的主要特点是没有变压器，采用高频化IGBT整流器，直流电压高，电池节数多，重量较轻，体积较小。
高频UPS无需增加滤波器，即可提高输入功率因数并降低整流器对前级电网的谐波污染。
工频机与高频机的区别
工频UPS与高频UPS的差异主要体现在输入电流谐波、输入功率因素、整流器技术、有无变压器、整机效率几个方面。
■ 两者的主要差异：
（1）工频UPS内置隔离变压器，技术成熟，某些产品占地面积甚至小于高频机（IGBT高频化UPS受制于元器件的容量，通常采用小功率模块并联方式实现500KVA，体积较大）；
（）高频UPS由于采用IGBT整流技术，其输入谐波及输入功率因素方面较有优势，由于采用直流升压电路提高了内部直流电压，因此无需输出变压器。higher requirements are put forward for the load-bearing capacity and safety reliability of tires. The manufacturing process of tire mainly includes three steps: first, different kinds of rubber, different oils, dyes and additives are mixed together to produce different parts of tire, such as liner, edge and tire surface. At the same time, it also needs to produce other parts, including steel strip required by tire; Next, the various parts of the tire are assembled through the tire forming equipment; Finally, the tire is fixed after heating and vulcanization. In this process, tire assembly is one of the most critical processes, and tire forming equipment has become the equipment that all tire manufacturers attach great importance to. Qingdao University soft control company is one of the professional manufacturers of radial tire forming equipment. Their customers include Hangzhou Chaoyang, Henan Fengshen, Liaoning Langma, Shandong Jinyu, Hengfeng, Sailun, Huanghai, Pingdu Guangming, etc. In order to help tire manufacturers produce high-quality tires faster and better, Qingdao University soft control company is committed to producing highly reliable tire forming equipment for the production of all steel radial truck tires.
