15. UPS TECHNOLOGY Slide 10/19/11 OFF-LINE UPS / STANDBY ON-LINE UPS / DOUBLE CONVERSION

16. Slide 10/19/11 POWER BASIC UPS SIZING ( if u know VA ) VA = voltage x ampere = 240V x 5amp = 1,200VA / 1.2kVA UPS > 1.2kVA

17. Slide 10/19/11 POWER BASIC UPS SIZING ( if you know Watt ) VA = 700 Watt / pf = 700 / 0.7 = 1,000VA / 1 kVA UPS > 1 kVA

18. Slide 10/19/11 EXAMPLES – SIZING UPS IT EQUIPMENTS CURRENT UPS PC – ACER M1800 3.15 Amp 756 V Server – HP Z400 6 Amp 1,440 V LAN Switch – HP Pro Curve 3500yl 24 0.6 Amp 144 V Gigabit Switch – HP Pro Curve 3500yl 48G 5 Amp 1,200 V Gigabit Swich + PoE – HP Pro Curve 3500yl 48G+PoE 3.3 Amp + 398W 1,361 V

19. Slide 10/19/11 POWER DENSITY VA While UPSs are generally measured in VA . . . Watts . . . The true output power of a UPS is measured in watts

20. Slide 10/19/11 POWER FACTOR eg: 10kVA UPS If pf 0.6  10kVA / 6kW pf 0.7  10kVA / 7kW pf 0.9  10kVA / 9kW Power factor is the ratio of watts to VA: Apparent power to Real power. VA (apparent) Watts (real)

22. Slide 10/19/11 ABM – ADVANCE BATTERY MGMT Charger Like other UPSs, the Powerware UPS is equipped with a charger that charges the battery. However, Powerware uses a unique charging technique that extends the life of the battery . . .

23. Slide 10/19/11 ABM – ADVANCE BATTERY MGMT ABM uses a 3-stage charging system: First, the battery is quickly charged to 90% to make sure the UPS is prepared for the next power outage. Second, ABM finishes charging the battery with a more moderate float charge. Charger

24. Slide 10/19/11 ABM – ADVANCE BATTERY MGMT Charger Third, ABM turns the charger off. This prevents the batteries from being overcharged. Feature Focus: Turning the charger OFF

25. Slide 10/19/11 The Result? The service life of the batteries is doubled so you won’t have to replace them as often as you would with competitive models. ABM – ADVANCE BATTERY MGMT
