Advantages

Disadvantages

 Handles 120V & 208V loads

 1.5-2% transformation energy loss

 Uses standard 240V panelboard & breakers

 208V requires 2 pole breaker

 Reduced wiring cost, 3W vs 4W

 Reduces the number of poles

 Transformer provides harmonic, noise and

fault current reduction 20

Battery of the Future? 20 year VRLA Stackable  Came out of Telecom market  Higher initial cost

– Spill containment not needed – More compact layout  Reduced maintenance cost for lower 15 year life cycle cost  Will it last 20 years in UPS application?

– Early version did not make more than a few years – Later versions have now surpassed 10 years use on UPS – Now with 5 year +15 warranty  Single string thru 1000 kVA  The Green battery due to

low float current, maintenance and recycling
