Sentence is too long, please supply a shorter sentence. Sentence is too long, please supply a shorter sentence. User Load; UPS output redundancy (70 ~ 80%) load peak factor (3:1) can not exceed inverter overload capacity load apparent power (Kva) can not exceed UPS rated power factor conversion factor three-phase load imbalance & LT; 30% . Harsh Electrical and physical environment: Power Supply Line voltage/frequency fluctuations, surge impact, peak subsidence, high frequency interference, environmental temperature and humidity instability, dust, corrosion and so on. STRUCTURE: input and output double isolation, steel chassis, high IP protection level. APPLICATION: Steel, chemical industry, electric power, automobile, paper, coal, oil, tunnel load type: heavy-duty machinery, production line equipment, DCS system, etc. . UPS working loss, ventilation, air conditioning configuration full load loss (KW) = kVACos (6 ~ 7.5%) air conditioning refrigeration capacity
differences are: INVERTER and charger integrated into one, the output through the tap jump transformer, to achieve subsection voltage stability. Power Level 0.7-20kVA on-line UPS operating principle no matter whether the grid voltage is normal or not, the AC voltage used by the load must go through the inverter circuit, that is, the inverter circuit is always in working state. Power Level 0.7-1500kVA about Delta Transform Operation Principle Delta Converter and compensation transformer to achieve voltage-stabilizing function, the main converter is a two-way converter. I can't stabilize the frequency. Power Class 10-480kVA comparison of four kinds of UPS (5) UPS power supply system a complete UPS power supply system is composed of front-end distribution (city power, generator, distribution cabinet) , UPS host, battery, back-end distribution, plus background monitoring or network monitoring software/hardware and other units. (6) UPS monitoring system composition UPS network monitoring system = intelligent UPS + network + monitoring software network monitoring software consists of the following three parts: SNMP card monitoring software security shutdown program UPS monitoring network
