统计显示,有90%的UPS用户疏于日常维护,导致电源发生故障,给企业带来无法挽回的损失。那么,如何对UPS电源进行科学的检测、维护?是目前困扰用户普遍存在的难题。河北凯翔电气科技股份有限公司利用现有专利技术研发、生产的UPS电源测试系统,可用于UPS电源的后备电池检测、UPS交流输出端带载能力测试,为UPS电源测试提供了一种更科学、全面的检测方式。凯翔UPS电源测试系统可模拟纯阻性、感性、容性负载及混合负载的启动
Statistics show that 90% of UPS users neglect routine maintenance, resulting in power failure, bringing irreparable damage to the enterprise. So, how to conduct a scientific test of UPS power supply, maintenance? Is currently puzzling users ubiquitous problems. Hebei Kaixiang Electrical Technology Co., Ltd. The use of existing patented technology research and development, production of UPS power supply test system can be used for backup battery UPS power supply testing, UPS AC output carrying capacity test for UPS power supply testing provides a more scientific , A comprehensive test methods. Kaixiang UPS power supply test system can simulate the pure resistive, inductive, capacitive load and mixed load start
