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 precauons should
be taken. All connecons 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 disconnecng
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.
Connecons 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 connecon of the load to the AC OUTPUT cable has exposed conductors, make this
connecon before connecng the AC OUTPUT cable to the UPS.
Connecons 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 insulaon.
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 insulaon.
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 baery pack is not inserted into the UPS, the baery is internally disconnected
from the power pins of the baery pack’s connector.
Even if this disconnecon were not present, the DC voltage of the baery is below the level
considered hazardous.
Do not apply external voltages to the pins of an exposed baery pack connector. It is not
possible to charge the baery 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 baery connector.
When the BATTERY PACK is not inserted into the UPS, the baery is internally disconnected
from the power pins of the baery 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 Descripon
The SynQor UPS-1500 3-Phase Series is an advanced technology military-grade uninterrupble
power supply (UPS) that uses lithium polymer baeries and highly ecient power electronic
circuitry to achieve a high power level and baery run-me in a low-prole, low-weight, rack-
mountable package. It provides voltage and frequency condioning, electrical isolaon, and
power ow smoothing between the power inputs and its power outputs. It provides baery
backed-up power when other power sources are not present.
A communicaon/control port is available to permit monitoring and control by a host computer
system. Front panel LEDs and an audible alarm provide informaon on the status of the UPS and
the baery 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 connecon 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 oponal 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 opons on the unit’s output conguraon. There are two
oponal DC outputs, available at various voltage and power levels. However, note that the
combined AC and the DC opon output power is limited to 1250 W total.
The electronic circuitry within the UPS-1500 Series products is designed, qualied 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 specicaons
for world-wide commercial ulity applicaons.
The UPS-1500 Series products are designed and manufactured to withstand the harsh
environments and use encountered in military applicaons. The electronic circuitry and baery
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
oponal aached connector covers are available for when the cables are not aached. The
UPS-1500 Series products comply with a wide range of tesng according to MIL-STD-810G.

Section II General Product Information
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 baery pack
that provides >10 minutes of full-power run-me, and 2) a 2U high unit that has an extended
baery pack that provides >24 minutes of full-power run-me. The former weighs approximately
32 lbs. and the laer 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 protecon 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 proles 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 disrupon
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 oponal
DC INPUT (secondary source) or the baery (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
connecon) 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 liming, Power Factor
Correcon (PFC), and high frequency isolaon. In the DC INPUT power opon, 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 oponal DC INPUT, a second electronic switch is closed which interconnects
the baery 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 isolaon and a pure-sinusoidal output voltage waveform.
An oponal electronic breaker can be added to the AC OUTPUT. This one pole hot side only
electronic breaker allows for fault tolerant, glitch free operaon when several UPS units are
placed in parallel. This opon is referred as “expanded” parallel opon.
Oponal DC outputs at various voltage and power levels are also available. The DC1 opon is
limited to 500 W. The DC2 opon can deliver up to 1250 W output.
INPUTThe DC1 and DC2 outputs are isolated from
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 baery charger circuit that draws power from the mid-bus. It ensures the baeries
are normally fully charged and that the various cells are properly equalized. The baery also
contains protecon circuitry to avoid damage due to improper charging or discharging, or to
excessive temperatures.
There is a communicaon/control port that provides a digital interface to a host computer system.

UPS Eciency
Figure 1 shows the typical eciency with which the UPS-1500 3-Phase series uninterrupble
power supplies delivers power to its AC OUTPUT from a 200 VrmsL-L/115 VrmsL-vN AC INPUT or
a 28 V DC INPUT. The inseron loss of the “Electronic Breaker” opon can be of up to 1% of the
total eciency at full load.

Total Output Power that can be derived from the AC INPUT
The total combined UPS output power (the AC OUTPUT power plus the oponal DC OUTPUT
power opons) for the UPS-1500 series is rated at 1250 W for an ambient temperature as high
as 55°C (131°F). Power is drawn rst from the primary AC INPUT (if voltage is within range) and
then the secondary DC INPUT (if voltage is within range) and then from the internal BATTERY
PACK (if it has sucient charge).
However, when the AC INPUT voltage is at the low end of its range (<100VL-vN AC) the UPS will
not be able to deliver its full rated output power in the steady-state without switching over to
either the DC INPUT (if it is available and >22 Vdc) or its internal baery. If one of the phases is
missing in the 3-Phase AC INPUT source the UPS will switch to the secondary DC INPUT source if
present, or the to the baery backup if the DC INPUT source is not available.

• If the AC INPUT voltage is above 100VL-vN, then the UPS can deliver its full rated output power
of 1250 W from the AC INPUT for an ambient temperature as high as 55°C (131°F) without
needing to switch over to the oponal DC INPUT or the internal BATTERY PACK
• If the AC INPUT is between 100VL-vN and 85VL-vN then the total output power that can be
derived from the AC INPUT linearly decreases from 1250 W at 100V L-vN to 1000 W at 85VL-vN.
For example, the total output power that could be drawn from the AC INPUT would be 1083
W at 90VL-vN. If the total output power is greater than this derated value, the UPS will switch
to the DC INPUT (if it is available and >22 V) or the internal BATTERY PACK.

Other opons may be available. Contact or visit the website:
for more informaon. If it is necessary to develop custom cables for your
applicaon, please read through the following secon for some important consideraons.
Both the input and output cables of the UPS carry substanal current, and since the wires in
these cables have resistance, the current owing through them causes a voltage drop from one
end of the cable to the other. In other words, the voltage across the cable at its downstream end
is smaller than the voltage across the cable at its upstream end. Mathemacally, the amount
that the voltage drops is equal to the resistance of the cable’s wire mulplied by the current
owing through the wire. It is therefore important to make sure that the resistance of the cable’s
wire is small enough to keep this voltage drop to an acceptable level.
While this is an issue for all of the power cables, it is parcularly important for the DC INPUT and
DC2 OUTPUT cables. DC current owing through these cables can be very high (65 A for the
UPS-1500 Series) while at the same me, the input voltage to the UPS is relavely small (22 V). A
common problem might develop due to high cable resistance (when the DC INPUT cable gage is
too small) which causes the input voltage to the UPS to fall below the 22V minimum. Under this
condion the UPS will switch to the internal baery pack for its power source even though the
voltage at the DC power source appears to be available and within proper range.
The resistance of a wire is also directly proporonal on its length. A wire twice as long as another
will have twice the resistance, holding all other things constant. The resistance in a cable is also
inversely proporonal to the cross-seconal area of the wire, which in turn is proporonal to the
square of the diameter of the cable. A wire with half the diameter of another will therefore have
four mes the resistance, holding all other things constant.
