| Detailed Product Description： | Product Description: Designed for communications-specific online UPS design of post and telecommunications industry, suitable for a 48V (or-48V) DC power (DC-screen) program-controlled switches, computer rooms, network, billing, server, and emergency lighting and other places. 48VDC DC power in a place where major electricity used to power the inverter power supply design. Features This series of online UPS designed specifically for the communications industry, suitable for a 48V (or-48V) DC power (DC-screen) program-controlled switches, computer room, network, billing, server, and emergency lighting and other places. 48VDc DC power in a power inverter to the important places with electrical equipment power supply, uninterruptible power than conventional (UPS) has the following advantages: 1, to avoid duplication of investment in batteries and reduce system maintenance and reduce system operating costs; 2, the DC power supply to the program-controlled switches are commonly used screen VRLA battery, the DC panel, high reliability, long life, thus adding DC power inverter, power supply reliability and longevity of its greatly increased. The batteries in conventional UPS is often no maintenance, no monitoring, but prone to damage the battery had failed to discover the situation: 3, due to room capacity 48V DC panel are larger, so when using inverter power supply, the grid can provide power long enough after the AC power supply time. Principles of Communication dedicated online UPS as shown below, the utility is normal, the AC mains input through the "input isolation transformer," "rectifiers", "inverter", "output isolation" after the power supply to critical loads, if AC input power from the engine room of the DC power will be through the "anti-anti-diode", "inverter", "output isolation" after power to the load; if the engine room of the DC power outage or maintenance, will still AC input power supply; if inverter failure or overload, static switch to immediately switch to "bypass input" loop, to ensure uninterrupted power supply load, once the troubleshooting inverter, static switch will switch back to inverter. ◆ Pure sine wave output: ◆ DC Inverter mains supply = 0 delay between the switching power supply: ◆ normal AC power supply without DC power consumption, no current anti-irrigation issues: ◆ standard communication interface: ◆ I called a special output filter circuit; ◆ cold start function; ◆ +48 V,-48V can be input. Very useful network favorites, www.wang1314.com go and experience! 1. The computer system crashes do not have to worry about loss of well-site collection; |
