The 3A3 UPS is new type three-phase input and three-phase output UPS systems. It adopted complete digitize control technology; compound various kinds of advanced technique of electric power industry and automatic control technology field. It’s a milestone of UPS industrial technical revolution. It’s improved the reliability of power facility. It’s designed with drawer style and high intelligent module, and easy to plug in or drawing out, so it can random arrange the UPS module quantity for different capacity between 15KVA to 120KVA; furthermore, it’s easy for maintains. It’s adopted wireless parallel redundant technique, decreased the fault rate of single point. 3A3 UPS system provides continuous, high-quality AC power to connect critical equipment, protecting them against any power disturbances due to blackouts, brownouts, surges, spikes, lightning and line noise interference. major UPS, ward UPS, apc UPS system
KEY FEATURES
·Excellent Electric Performance
* Low input harmonic current: <5%
* High accuracy output voltage:<2%
* Strong overload ability:It can continues work 10 minutes when overload of 110~130%,and continues work 1 minute when overload of 130~150%
* Large charger current:4.5A(each module)
* Support the frequency conversion, 50Hz input* 60Hz output or 60Hz inpu t
* 50Hz output
·Complete digitize control
The 3A3 UPS module adopt the advanced DSP of TI Corp. as it’s central control, the mighty operation ability can make software finish most of work that by components before. It’s not only to provide more higher reliable degree & accuracy degree, but also convenient to upgrade & attendance.
·Intelligence Charge Way
The 3A3 UPS adopt the advanced three step charge way: the first step is charged by large residual current, quick return charge about 90% capacity; the second step is charged by pulsation, it can make the battery with proportional current and make the battery charge fully; the third step is continue charge by the constant voltage, it can guarantee the battery without any losses. So the battery can quick charge fully and also can extend the use life and the user can save large unnecessary cost.
·The Higher Power Density
One UPS module of 3A3 UPS is 440×700×131mm(3U), one standard UPS chassis with height 2M can install max. 8 nos UPS module, the total capacity up to 120KVA; furthermore, include the distribution panel. And then arrange one similar size battery chassis for them only, one set of UPS systems, major UPS is ok. Because the UPS chassis and the battery chassis all use standard chassis, the size is same as most of load chassis, so the complete UPS systems can install on the side of load chassis and don’t need any additional special UPS distribution room. It’s beautiful and can save large money for user.
·N+X Wireless Parallel Redundancy
Adopted the advanced wireless parallel connect control technology, it decrease the fault rate of simple point (When stable working, it still can work on normal mode even if the parallel connect wire out of work.). It improved the reliable degree and more better than the wired parallel redundancy.
·Same Battery Pack for Redundant System
The 3A3 UPS adopted double battery input structure and advanced control technology, all the parallel UPS systems, major UPS use the same battery pack. It can save the cost of battery pack.
·Flexible System Arrangement
The 3A3 UPS is designed with UPS module, and it is easy to plug in or drawing off. The complete systems including UPS module, communicate module, distribution panel and chassis. We also can provide some optional accessory. The UPS module and communicate module can change even if the system on working mode. The changes do not disturb other parts work normally. The new added module do not need any adjustable and direct into the system. It’s convenient to enlarge the system capacity or maintain the system. User can choose the different quantity of module between 15KVA to 120KVA as per require. If need to enlarge the system capacity future, user need to plug in several UPS module, major UPS only.
·Majorized Power System Topology
The 3A3 UPS compound the advantage of center style and disperse style power supply topology, designed with areal power supply way. If divide several area in a large data machine room, and arrange one or two 3A3 UPS system (Parallel Redundancy) each one area, install the UPS system, major UPS, ward UPS, apc UPS system on the side of load facility and supply the electric through the distribution panel of chassis; then every area all are centralized power supply and management. And different area is different separate power supply and wiring. So it can avoid the grave electric fault at large area.
·Humanization Operate Interface and Perfect Power Management Software
The parallel system adopted large LCD display as the operate interface, it’s very easy to operate the system and study all relevant data. It will be more better if use together with the monitor software WINPOWER2003. It also can remote management after use the optional SNMP card.
·Superhigh System Usability
If the UPS parallel redundancy up to two modules or more, then the usability of UPS system can up to 99.999% or more. The MTBF up to 1500 myriad hours or more.
·Least Shut-off Time for Maintenance
If the quantity of fault UPS module less than or equal the redundant UPS modules, then can change the faulty UPS module on-line and don’t need to disturb others UPS module, and the shut-off time is zero when this situation; if the quantity of fault UPS module more than the redundant UPS module, the shut-off time less than 5 minutes, because it’s change the UPS module, major UPS, ward UPS, apc UPS system only.
