[RE-wrenches] -48 Volts at the Phone Company

[Keith Cronin]

Hi folks

Any inverters in the marketplace that will happily take -48 volts off the phone companies standard battery banks they use to backup their phone network for us?

Client wants to drive a 15kva load and replace and existing conventional UPS system that was rated for 40kva.

 
Thanks
Keith Cronin
