Smart UPS is an extremely reliable sine wave uninterruptible power system designed to keep
computers and peripheral devices such as monitors, storage subsystems, modems, tape drives,
etc. performing from utility line failures which could result in damage of data. In the event of
utility failure, the Smart UPS supplies power to your equipment derived from a battery within
the UPS and provides visual and audible indicators which alert you to utility line failures.
Therefore, the user has ample time to save file and close operations. Whenever the Smart UPS
is plugged in, the Smart UPS maintains the battery in a charged condition and serves to protect
your equipments from surges and noise brought from utility.
The main features include:
Pure sine wave output.
Automatic Voltage Regulation (AVR).
Advanced equipment & data protection from blackouts, brownouts, sags,
AC line noise and surges.
Adjustable input power range settings to meet your power source requirement.
Full analytical high performance micro processor control with true RMS synchronous calculation
Intelligent battery management for battery status, battery power saving & battery replacement control.
DC direct start up capability, complete diagnostic indication and control.
Standard RS-232 communication interface.
Telephone RJ11 & Network RJ45 surge protection.
Expansion slot is for optional SNMP CARD for network management / monitor.
Smart series include 700VA/1000VA/1400, Smart series have 50Hz & 60Hz autosensing
function.

甲、 工作原理
i. 由 CB1、T1、C21、C25、C26構成E.M.I. FILTER來過濾AC-LINE的
NOISE。
ii. RV1、RV2、RV3為電源SURGE保護模組,可吸收突波能量,型號為
471KD20,最高電壓為330V,吸收突波能量為110焦耳,一旦AC Line 輸
入電壓過高或是有雷擊之現象能量太大時,MOV會形成短路狀態,已達
到雷擊保護或電壓過高之保護。
乙、 關鍵技術
i. T1為依EMI調整,一般都在經多次測試固定之後,不得修改。
