Where the power module can be connected in parallel, the average share the load. In case of failure to automatically exit the system, from other power module to bear the load, both horizontal and vertical scale. Unique redundant and machine technology enables equipment without single points of failure, to ensure maximum availability of the power supply. All modules can be hot, you can implement an online replacement, maintenance is the most secure power protection programmes. The programme is modular UPS host, intelligent power distribution system and battery. Modular UPS Host: modular UPS power module using double-conversion on-line structure, including the rectifier, inverter, battery charger, control circuit, and input and output battery bus of circuit breaker switch. With input power factor compensation function. All modules are available online hot-plug replacement, providing the highest levels of availability, and serviceability. Modular UPS host control module adopts industry CAN BUS bus control structure, by two redundant hot-swappable control module to control the management of the system. A control module failure does not affect the system's functioning. Control module can be online hot plug replacement. Power modules in parallel by concentrated control module, in accordance with the uniform management and machine parameters run, a power module fault can automatically exit the parallel system, does not endanger the entire parallel system. Modular UPS system with independent static bypass module, do not use more than one static bypass structure to avoid the transfer of multiple bypass-bypass not current overload damage caused. Module parallel output voltage accuracy of ± 1%, and machine circulation < 1%. Standard SNMP card, using the HTTP protocol, SNMP protocol, TELNET Protocol, etc. For UPS power status, battery status, bypass status, inverter status, post status, power-on status and input voltage, output voltage, load percentage, input frequency, battery voltage, battery capacity, battery discharge time, UPS will be inched if the internal temperature, ambient temperature, and so on operation of the ups at a glance, UPS power protection system of management efficiency and management quality. Choose Open windowsNT/windows2000/windows2003 windowsXP/operating system platforms. You can choose equipped with temperature and humidity sensor, insert the all-in-one network card, network computer room environment temperature and humidity monitoring and alerting. Intelligent power distribution system is the system for UPS power input and output integrated power distribution system, and supporting the use of UPS host, including UPS input switching, output switching and maintenance bypass switch and the system of total input switch on main switch is configured auxiliary contacts; containing current sensing system and host communication with the ups. The distribution system by input power distribution unit, tap output power distribution module, monitoring module, isolation transformers. Output power distribution units each power distribution module configuration 18 output branch, each tap current setting from 6A-32A on demand and according to the site load configuration and change adjustment phase equilibrium distribution system can be installed up to six plug-type power distribution module, power distribution module number is optional. The distribution system and UPS host with dimensions appearance, with color. Standard: liquid crystal display, UPS maintenance bypass Panel (including the system of total input switch, UPS input switching, output switch, maintenance bypass switch, with auxiliary contact switch). Detection circuit boards, three-phase input and output voltage and current sensor Assembly, transfer current, ground current sensors, signal interface external EPO. Optional input K value isolation transformer and branch current monitor. The distribution system can be equipped with network cards, can network monitoring the distribution Cabinet of parameters, status, and history, and alarm information. Can network monitoring distribution Cabinet of input and output three-phase voltage, current, frequency, current, ground current, each phase of the number, the number KVA, KW, branch current power factor. And can set current and low voltage alarm threshold values. External battery and battery Cabinet battery fully closed with maintenance-free lead acid battery, the battery capacity of the brand can be configured as needed, the battery installed on the same host with the UPS brand of the same color with the appearance of battery Cabinet. · modular single UPS system reliability analysis to assess the performance of their duties of reliability, should not only consider the MTBF, UPS will also consider the MTTR and power UPS of MTBF. When UPS failed at the same time, the city also fails, the load will lose power, that is the key responsibilities of the UPS. Load exposure without protection of commercial power beneath the length of time depends on the length of the maintenance time. If the maintenance one ups required one week, while the city's average time without undue Cheung is a week, so, UPS fails, the load will most likely lose power. If the UPS is 1 hour MTTR, city of MTBF is not on the critical load of failure probability have a significant impact. Obviously, reducing MTTR of UPS will reduce the probability of the critical load. Reduce MTTR UPS of the best approach is to minimize maintenance may affect the UPS. Modular single UPS because online hot-swap feature, the nature are the bestSelect. From the design principle, assume the task of the entire power supply systems must be highly "fault-tolerant" features redundant power supply scheme-in order to ensure that whatever is in the commercial power grid failure or any modules (including system control module) fails, or is undergoing routine maintenance/repair operation, or for any resulting fuse burned/breaker "trip", Internet device shall consist of the "on-line ups" inverter power supply, instead of entering the city by the ordinary power/emergency standby generator via UPS AC bypass to the status of the power supply. In sum, the modular single UPS has the longest duties mean time between failures (λ s m I s I o n), the smallest mean time to repair (MTTR) and the strongest antioxidant power interference risks and highly fault-tolerant "feature" is the most reliable electricity guaranteed. · modular single UPS solution map:
