Page 12: Normal Operation Mode
Always On UPS Systems Normal Operation Mode Figure 3.2.1 Normal Mode Operation rectifier/charger converts the supplied AC power into DC (bus) power, which is then supplied to the inverter and the battery charger. The DC to AC inverter then supplies continuous, noise free AC power to the critical loads. The inverter output is synchronized with the bypass AC power source provided that the bypass AC power source is within the specified frequency range. -
Page 13: Reserve Mode
Always On UPS Systems Reserve Mode: Figure 3.4.1 Reserve Mode Operation If the inverter is placed into an abnormal condition, such as over temperature, short circuit, abnormal output voltage or is overloaded for a period which exceeds the inverter’s limits, the inverter will automatically shutdown in order to protect itself. -

Page 16: Rectifier
In order to further improve the power factor and reduce harmonic current drawn by the rectifier, Always On UPS’s above 80kVA incorporate a 12-pulse full controlled rectifier (also available as an option on the 10 to 60kVA UPS’s) to reduce the total harmonic current to less than 12%. A phase shift transformer is added with input inductors to achieve this higher level of performance while maintaining our high input power factor. -
Page 17: Inverter
Always On UPS Systems Inverter Figure 3.8.1 Inverter Layout The inverter is composed of IGBT’s, inductors, capacitors, highly efficient filters, control circuitry and protection circuitry. This inverter inverts the DC power received on the DC bus to isolated, noise-free AC power, which is then supplied to the critical loads. Our PWM wave generator is switching at a higher frequency well above the human audible range. -

Page 25: Storage
The RAM is supplied by a small backup battery located on the Controller board. If the storage time of the UPS exceeds 1 year, these functions should be verified by an Always On Service Center before putting the UPS into operation. 6.3.2 STORAGE OF BATTERY Although this system includes maintenance free batteries, keep in mind that they are subject to self-discharge and therefore must be recharged. -
Page 26: Site & Environment Consideration
Always On UPS Systems Site & Environment Consideration The designed function of the UPS is to provide a safe, clean and independent electrical supply free from random variations, disturbances or interruptions of the utility mains. The UPS will provide a constant power source, which is regulated in both voltage and frequency. When the utility mains are not available, the UPS will provide optimal back-up time depending on the capacity connected battery bank. -
