UPS-1500 3-Phase Guide
www.synqor.com
The UPS-1500 Series has two product formats: 1) a 1U high unit that has a standard battery pack
that provides >10 minutes of full-power run-time, and 2) a 2U high unit that has an extended
battery pack that provides >24 minutes of full-power run-time. The former weighs approximately
32 lbs. and the latter 50 lbs.
The SynQor UPS-1500 Series products are designed and manufactured in the U.S.A.
Product Topology
The SynQor UPS-1500 Series products use a true on-line double conversion topology that
provides protection to the load from spikes, noise, surges, brownouts, blackouts, etc. in the
input power sources. This topology also provides smoothing of load transients and nonlinear
load profiles so that the input power sources are not subjected to these type of disturbances.
There is a seamless transfer from any power source to another so that there is no disruption
in the output voltage waveform.
As the figure below shows, there is a nominal 28 V mid-bus within the UPS that draws power
from one of up to three power sources: the 3-Phase AC INPUT (primary source), the optional
DC INPUT (secondary source) or the battery (backup source). EMI filters are present at all
external inputs and outputs.
