Section I Warnings
Hazardous Voltages
The INPUT and OUTPUT Power connectors and cables of the SynQor UPS may have voltages that
are unsafe. INJURY OR DEATH ON CONTACT may result. Appropriate safety precauons should
be taken. All connecons should be made in accordance with LOCAL ELECTRICAL CODES.
• The UPS CHASSIS should be connected to earth or system ground with Ground Stud on the
rear panel, see mechanical diagrams.
• For the AC INPUT cable and connector:
 Do not assume that a hazardous voltage is not present at the terminals of the AC INPUT
connector, even if the UPS appears to be “OFF”.
 Do not make contact with the terminals of the AC INPUT connector.
 Always connect the cable to the UPS before it is connected to the source of AC power.
 Always disconnect the AC INPUT cable from the source of AC power before disconnecng
it from the UPS.
If the AC INPUT cable is connected to the source of AC power and not connected to the UPS,
do not contact the exposed terminals of the AC INPUT cable.
 Do not assume that the source of AC power is not present.
 Connecons between the AC INPUT cable and the source of AC power should not be accessible.
• For the AC OUTPUT cable and connector:
Do not assume that a hazardous voltage is not present at the terminals of the AC OUTPUT
connector, even if the UPS appears to be “OFF”.
 Do not make contact with the terminals of the AC OUTPUT connector.
Connect the AC OUTPUT cable to the UPS before the UPS is turned “ON”.
 If connecon of the load to the AC OUTPUT cable has exposed conductors, make this
connecon before connecng the AC OUTPUT cable to the UPS.
 Connecons between the AC OUTPUT cable and the load should not be accessible.
• For the DC INPUT cable and connector (if present):
The rated DC INPUT voltage of the UPS is below the level considered hazardous.
The DC INPUT terminals of the UPS are isolated from the AC INPUT and AC OUTPUTS with
reinforced safety insulaon.
 However, never assume the terminals of the DC INPUT connector or the wires of the DC
INPUT cable are safe to contact, not even if the UPS or DC INPUT source appears to be “OFF”.

Section I Warnings
006-0007129 10/12/2018 Rev B 5 of 60 UPS-1500 3-Phase Guide www.synqor.com
• For the DC OUTPUT cable and connector (if present):
The rated DC OUTPUT voltage of the UPS is below the level considered hazardous.
The DC OUTPUT terminals of the UPS are isolated from the AC INPUT and AC OUTPUTS with
reinforced safety insulaon.
 However, never assume the terminals of the DC OUTPUT connector or the wires of the DC
OUTPUT cable are safe to contact, not even if the UPS appears to be “OFF”.
• For the BATTERY PACK (if not inserted into the UPS):
 When the baery pack is not inserted into the UPS, the baery is internally disconnected
from the power pins of the baery pack’s connector.
 Even if this disconnecon were not present, the DC voltage of the baery is below the level
considered hazardous.
 Do not apply external voltages to the pins of an exposed baery pack connector. It is not
possible to charge the baery pack from an external source. An external voltage could
damage the pack’s internal control circuitry.
Hazardous Energies
The INPUT and OUTPUT Power connectors and cables of the SynQor UPS may be the source of
high levels of energy. Do not inappropriately make electrical contact between any terminal of a
connector and another, or between any wire of a cable and another, or between any terminal or
wire and the UPS’s chassis or ground. DAMAGING ELECTRICAL ARCS may result upon contact. Care
should be taken to avoid accidental electrical contacts of any sort with the baery connector.
When the BATTERY PACK is not inserted into the UPS, the baery is internally disconnected
from the power pins of the baery pack’s connector. An electrical contact between any two of
these power pins or between any power pin and ground should therefore not be damaging the
pack. However, care should be taken to avoid accidental electrical contacts of this sort.

Section II General Product Information
Product Descripon
The SynQor UPS-1500 3-Phase Series is an advanced technology military-grade uninterrupble
power supply (UPS) that uses lithium polymer baeries and highly ecient power electronic
circuitry to achieve a high power level and baery run-me in a low-prole, low-weight, rack-
mountable package. It provides voltage and frequency condioning, electrical isolaon, and
power ow smoothing between the power inputs and its power outputs. It provides baery
backed-up power when other power sources are not present.
A communicaon/control port is available to permit monitoring and control by a host computer
system. Front panel LEDs and an audible alarm provide informaon on the status of the UPS and
the baery pack.
The UPS-1500 3-Phase Series products draw power from a 200VL-L/115VL-N AC INPUT connected
in delta. Note that since the UPS input is in delta, no physical neutral input connecon exists.
Line to neutral “INPUT”voltages discussed throughout this document are conceptual, not
physical. Line to neutral voltages will be referred in this document as line to virtual neutral
“” for discussion purposes.
The UPS grants a high degree of exibility in terms of supplying power to the unit. The AC INPUT
accepts a wide frequency range (45-800Hz). An oponal 28 V nominal DC INPUT may also be
used. The AC INPUT has priority over the DC INPUT. The UPS provides up to 1500 VA and 1250 W
of AC OUTPUT power at 115 or 230 Vac. The pure sine wave AC OUTPUT voltage can drive
any non-linear load with a crest factor up to 2.5, and any load power factor from 0.0 to 1.0.
The UPS-1500 also provides several opons on the unit’s output conguraon. There are two
oponal DC outputs, available at various voltage and power levels. However, note that the
combined AC and the DC opon output power is limited to 1250 W total.
The electronic circuitry within the UPS-1500 Series products is designed, qualied and screened
according to SynQor’s MIL-COTS Standards. It complies with the requirements of MIL-STD-704F,
MIL-STD-1399-300B, MIL-STD-1275D and MIL-STD-461F, as well as IEC-EN61000 specicaons
for world-wide commercial ulity applicaons.
The UPS-1500 Series products are designed and manufactured to withstand the harsh
environments and use encountered in military applicaons. The electronic circuitry and baery
are contained in a sealed chamber constructed from a die-cast aluminum chassis that is weather-
proof and shock- proof. Redundant, water-proof fans on the rear panel draw cooling air over
the heat-sink ns below the sealed chamber. Military-grade circular connectors are used, and
oponal aached connector covers are available for when the cables are not aached. The
UPS-1500 Series products comply with a wide range of tesng according to MIL-STD-810G.

006-0007129 10/12/2018 Rev B 8 of 60 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 baery pack
that provides >10 minutes of full-power run-me, and 2) a 2U high unit that has an extended
baery pack that provides >24 minutes of full-power run-me. The former weighs approximately
32 lbs. and the laer 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 protecon 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 proles 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 disrupon
in the output voltage waveform.
As the gure 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 oponal
DC INPUT (secondary source) or the baery (backup source). EMI lters are present at all
external inputs and outputs.

Power ows into the unit from the AC 3-Phase delta connected INPUT (no neutral wire
connecon) through a power switch. Internal fuses in the input protect the unit in the event
of a hardware failure of the 3-Phase AC to DC INPUT stage. 
 The 3-Phase AC to DC INPUT stage provides input current liming, Power Factor
Correcon (PFC), and high frequency isolaon. In the DC INPUT power opon, power ows
from the DC INPUT through an electronic switch that is closed when the AC INPUT power
is absent and the DC INPUT voltage is within valid range. If power is not available on the AC
INPUT or in the oponal DC INPUT, a second electronic switch is closed which interconnects
the baery to the mid-bus.
The AC OUTPUT is created by an inverter that draws power directly from the mid-bus. This
inverter provides high frequency safety isolaon and a pure-sinusoidal output voltage waveform.
An oponal electronic breaker can be added to the AC OUTPUT. This one pole hot side only
electronic breaker allows for fault tolerant, glitch free operaon when several UPS units are
placed in parallel. This opon is referred as “expanded” parallel opon.
Oponal DC outputs at various voltage and power levels are also available. The DC1 opon is
limited to 500 W. The DC2 opon can deliver up to 1250 W output. 

each other and from the AC OUTPUT.
Bulk energy storage capacitors are connected to the mid-bus to help smooth imbalances in
power ow between the inputs and outputs of the UPS.
There is a baery charger circuit that draws power from the mid-bus. It ensures the baeries
are normally fully charged and that the various cells are properly equalized. The baery also
contains protecon circuitry to avoid damage due to improper charging or discharging, or to
excessive temperatures.
There is a communicaon/control port that provides a digital interface to a host computer system.
