电力用交流不间断电源
- 产品详情
产品简述
目前，电力系统的继电保护，微机控制和事故照明等设备都需要交流不间断电源供电系统，电力专用交流不间断电源（以下简称电力专用UPS电源）与电力直流操作电源系统一起，组成发电厂、变电站的专用不间断电源，向微机、通讯、载波、事故照明及其它不能停电的设备供电。从电厂或变电站现有直流操作电源取电，不必像常规UPS那样需要单设蓄电池组，从而避免蓄电池的重复投资，减少系统维护，降低运行成本。
功能特点
● 采取成熟的数字控制电路，PWM+SPWM脉宽调制技术，在任何负载情况下都可输出高品质正弦波；
● 先进的电气隔离技术，实现直流与交流电路的完全隔离，保证各电源系统间不干扰；
● 使用先进的抗干扰技术和优异的EMI/EMC设计，具备良好的电磁兼容性；
● 完善的过欠压、过温、过流及短路保护，输入反接保护及输入缓冲保护功能，提高产品的可靠性；
● 采用静态电子切换开关，逆变、旁路输出不间断切换；
● 提供RS485通讯接口和干接点输出，支持实时数据通讯功能；
● 可采用立式、19寸标准机架式和机柜组屏三种安装方式。
