New Product - the Ferro-resonant UPS.... FerrUPS

Ferro-resonant UPSes are a 3rd type (or topology) of UPS.  Unlike the line interactive or double conversion, ferro-resonant units use a transformer to hold energy long enough for the UPS to transfer to the batteries.

The most common is the FerrUPS.  Branded under Best Power, Powerware and still made by Eaton.  These type of units are very robust and highly sought.  Many times we have have tried to get customers to leave their FerrUPS to no avail.  So we have now started selling a few models.

FerrUPS are best used in industrial applications where the load may spike under certain condition.  Since it continuously 'saturates' the internal transformer these spikes are absorbed without incident.

Look for our Ferrups 10kva later this month.  Unlike some of the other UPSes, these units need quite a bit of work to be refurbished.  DONT BUY A USED ONE!!!   Buy from a trusted supplier like GreenlightUPS
