18. UPS (UNINTERRUPTIBLE POWER SYSTEM ) • One or three phases • Power factor correction • Over voltages and over currents protection • Deleting noises EMI RFI • Capabilities: • 350 VA – 1500 VA • 1500 VA – 6000 VA • 6000 VA – 30 kVA • Transfer time: less than 4 ms • Not require large spaces • They are comfortable to displace.

19. HOW DOES IT WORK? • Other parts: • Regulator • Control components • Communication ports • Analog to digital converter Takenfrom: http://www.renesas.eu/ecology/system/

25. CONCLUSIONS • Emergency systems are indispensable in places like hospitals where a moment without energy can risk someone´s life. • These systems are so useful to prevent data loss or if you can´t stop a process for a period of time. According with the use that you need, one system will be more appropriate than other. • Each system has different characteristics about its functionality and it´s useful to understand them before it is implemented.
