Products Introduction: 2000 Series Offline UPS provides the safest and most reliable power protection for your company. Its back up power allows you to keep working under short or long time power off situation. It can also protect your facilities, to avoid the damage caused by the surge from transmission of transmission line and telephone line. High-powered surge suppressor can protect your computer from electronic noise and destructive surges. Main characteristrics of Smart UPS is Automatically adjust high voltage & low voltage function. (Automatic Voltage Regulator), AVR can adjust high/low voltage to safe level immediately, which lets you work indefinitely when is power shortage and over-voltage situation., under the most power-needed situation when the power was off, it can also work perfectly without battery. As regards of other features, such as several voice alarms, LED indicator lights, RS323 and USB intelligent communication interface, RJ11 and RJ45 surge production interface and optional input power cables and output sockets, all these outstanding functions makes Smart UPS become the best facility to protect production from continuous threat of power problem & data loss. Features: 1)Adopting the pulse width modulation (PWM) technology and the advanced MOSFET power apparatus, it made the UPS running more stable. 2)The UPS has the function of automatically adjust high voltage & low voltage (AVR) and with 145Vac-280Vac wide range of input, so it can adapt to any adverse electrical environments. 3)The UPS has designed with Bypass socket, so it could connect to the high capacity load but without damaging the UPS. 4)Advanced automatic constant current charging circuit, which extended battery life. 5)Equipped with a perfect battery low voltage, overload, short circuit protection. 6)Built-in maintenance free valve-regulated lead-acid batteries with high quality and the power are sufficient. 7)RS232 and USB smart communication interface, RJ11 and RJ45 FAX/MODEM Protection (Optional). Applied Scope: Computer Network Server Workstation Small Office Environment Automatic Teller Machine Monitoring System
