因特网的高速发展和PC的家庭普及化,使面向个人办公和家庭PC用的小功率UPS电源的需求急速膨胀,也使此类UPS产品成为了UPS市场的一个新热点。近日,《微电脑世界》评测实验室测试了一款来自美国PCM公司的小功率UPS电源产品——BNT—400A,它是专为单机用户设计的智能在线互动式不间断电源,输出功率较小,只有400VA。BNT—400A采用了全塑外壳,具有体积小、重量轻的优点;它运用单片机作控制器,是一种具备自我保护和故障诊断能力的智慧型UPS。BNT—400A提供2个通用输出插座,负载容量达240W;具有在线稳压功能,当市电过高或过低时
The rapid development of the Internet and the popularization of the PC family make the demand for low-power UPS power supply for personal office and home PC rapid expansion, making such UPS products become a new hot spot in the UPS market. Recently, “Microcomputer World” testing laboratory tested a low-power UPS power supply from the United States PCM company product - BNT-400A, it is designed for a single user intelligent online interactive uninterruptible power supply, the output power is small, Only 400VA. BNT-400A uses a plastic housing, with small size, light weight advantages; it uses a microcontroller as a controller, is a smart self-protection and fault diagnosis UPS. BNT-400A provides two general-purpose output sockets, load capacity of 240W; with online regulator function, when the electricity is too high or too low
