FT600/800/1000-D型准在线式方波UPS(不间断电源)采用高频技术及脉宽调制(PWM)技术,从根本上取消了铁芯变压器,无论效率及性能较同类产品都有所提高。该机型具有体积小、重量轻、操作简便、实用电压范围宽、耐冲击性能强等特点;同时还具有恒流充电、电池欠压报警、保护、市电检测与自动切换、过负荷报警、短路保护、温度保护等功能。在此就FT1000-D型而言.对其原理及维修作一系统介绍。
FT600 / 800/1000-D quasi-online square wave UPS (uninterruptible power supply) using high-frequency technology and pulse width modulation (PWM) technology, fundamentally canceled the core transformer, regardless of efficiency and performance than similar products have Increased. The model has the characteristics of small size, light weight, easy operation, wide range of practical voltage, impact resistance and other characteristics; also has constant current charging, battery undervoltage alarm, protection, mains detection and automatic switching, overload alarm, Short circuit protection, temperature protection and other functions. In this FT1000-D type in terms of its principles and maintenance for a system introduction.
