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 o.
 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.
 Connections 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 o.
 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, even if the UPS or DC input source appears to be o.

Section I Warnings
006-0006504 02/27/18 Rev R 5 of 56 UPS-3000 Guide www.synqor.com
• For the DC OUTPUT cables and connectors (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 cables are safe to contact, even if the UPS appears to be o.
• 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, and excess voltages could
damage 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. Care should
be taken to avoid accidental electrical contacts of this sort.
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. However,
care should take to avoid accidental electrical contacts of this sort.

Section II General Product Information
Product Descripon
The SynQor UPS-3000 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-3000 Series products can draw power from an AC input having a wide range of voltage
and frequency levels, or from an oponal 28 V nominal DC input. The AC input has priority over
the DC input. The UPS provides up to 3000 VA and 2500 W of AC output power at 115 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. There are two oponal DC outputs at various voltage and
power levels. The total AC plus DC output power is limited to 2500 W.
The electronic circuitry within the UPS-3000 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-3000 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-3000 Series products comply
with a wide range of tesng according to MIL-STD-810G.
The UPS-3000 Series is a 2U high unit that has two standard baery packs which provide >10
minutes of full-power run-me and weighs approximately 65 lbs.
The SynQor UPS-3000 Series products are designed and manufactured in the U.S.A.

006-0006504 02/27/18 Rev R 8 of 56 UPS-3000 Guide www.synqor.com
Product Topology
The SynQor UPS-3000 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. They also provide smoothing of load transients and nonlinear load
proles so that the input power sources are not subjected to these 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 AC INPUT, the oponal DC INPUT or the baery
(with that order of priority based on availability). EMI lters are present at all external inputs
and outputs.

Power ows from the AC INPUT through an AC-DC converter that has Power Factor Correcon
(PFC) and high-frequency safety isolaon stage. 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 its specied range. Otherwise, a second electronic switch is closed to connect the baery
to the mid-bus.

Section II General Product Information
006-0006504 02/27/18 Rev R 9 of 56 UPS-3000 Guide www.synqor.com
The AC OUTPUT is created by an inverter that draws power 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.
Oponal DC outputs at various voltage and power levels are available. The DC1 opon provides
two separate 500 W outputs which cannot be used directly in parallel. The DC2 opon provides
a single parallelable output up to 2500 W. When the DC2 opon is selected, the DC Input is not
available. The DC1 and DC2 outputs are isolated from each other as well as 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 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.

Total Output Power that can be derived from the AC INPUT
The total UPS output power (the AC OUTPUT power plus the oponal DC OUTPUT power) for
the UPS-3000 series is rated at 2500 W for an ambient temperature as high as 55oC (131oF). It
draws this power rst from the AC INPUT (if its voltage is within range) and then the DC INPUT
(if its voltage is within range) and then from the internal BATTERY PACK (if it has sucient
charge).
However, when the AC INPUT voltage is at the low end of its range (<90 Vrms) or the ambient
temperature is at the high end of its range (>45oC/113oF) 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 baery. Figure 2 indicates the total steady-state output
power that the UPS can derive  under these extreme condions. See Figure

• If the AC INPUT voltage is above 105 Vrms, then the UPS can deliver its full rated output power
of 2500 W from the AC INPUT for an ambient temperature as high as 55oC (131oF) without
needing to switch over to the oponal DC INPUT or the internal BATTERY PACK.
• If the AC INPUT is between 90 Vrms and 80 Vrmsthen the total output power that can be
derived from the AC INPUT linearly decreases from 2500 W at 90 Vrms to 2000 W at 80 Vrms
(except for at the high end of the ambient temperature range – see below). For example, the
total output power that could be derived from the AC INPUT would be 2250 W at 85 Vrms as
long as the ambient temperature is not above 50oC (122oF). 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.

• If the AC INPUT voltage is 90 Vrms the ambient air temperature is above 45oC (113oF),
the total output power that can be derived from the AC INPUT linearly decreases from 2500
W at 45oC (113oF) to 2000 W at 55oC (131oF). For example, the total output power that could
be derived from the AC INPUT would be 2250 W at an AC INPUT voltage of 90 Vrms and an
ambient temperature of 50oC (122oF). A higher output power than this would cause the UPS
to switch over to its DC INPUT or the internal BATTERY PACK.
• When the AC INPUT voltage is between 105 Vrms and 90 Vrmsthe ambient temperature
is between 45oC and 55oC, the total output power that can be derived from the AC INPUT
can be calculated by linearly interpolang between the curves shown. For example, the total
output power that can be derived from the AC INPUT when the voltage is 97.5 Vrms would
be 2500 W up to an ambient temperature of 50oC (122oF) and then derate to 2250 W at 55oC
(131oF).
Furthermore, there is a limited (and uncommon) range of AC INPUT voltage between 132 Vrms
and 160 Vrmsin which the total output power that can be derived from the AC INPUT is also
derated, as shown in the graph below.

Note that the full rated output power of 2500 W can be derived from the AC INPUT having a
voltage within this uncommon range for 15 seconds before the UPS will switch over to the DC
INPUT or the BATTERY PACK. Also the UPS can drive full rated power for a 2 second interval even
if the AC INPUT voltage drops below 90 Vrms.

Addionally, while the AC output is loaded to 1500 W or greater, the available DC1A and/or DC1B
output power is reduced as shown in Figure 4. In order to achieve the rated DC1 output power,
the AC output must be loaded to less than 1500 W. For example, if the AC output is loaded to
2000 W and both DC1 outputs are to be used to achieve a total of 2500 W, they must be equally
loaded to 250 W. Similarly, if the AC output is loaded to 2000 W and if either DC1A or DC1B is
desired, it can only be loaded to 250 W.

Other opons may be available. Contact [e-mail] or visit the website: www.synqor.com for more
informaon. If it is necessary to develop custom cables for your applicaon, please read through the following
secon for some important consideraons. Damage caused by improper wiring of cables will not be covered
under SynQor’s warranty.
Both the input and output cables of the UPS carry substanal 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. Mathemacally, the amount that the voltage drops is equal to the resistance of the cable’s wire
mulplied by the current owing through the wire. It is therefore  to make sure that the 
 enough to keep this voltage drop to an acceptably small value.
While this is an issue for all of the power cables, 
because the current owing through it is very high (as high as 124 A for the UPS-3000 Series)
and the voltage across it is already relavely small (as low as 22 V). In fact, a common problem that arises
(when the DC INPUT cable has too small a wire) is that the voltage seen at the DC INPUT of the UPS falls below
the minimum specied value of 22 V even though the voltage at the source of the DC power is greater than
22 V. Under this condion the UPS will switch to the internal baery pack for its power source even though the
voltage at the DC source of power appears to be available and at a proper level.
The resistance of a wire depends directly on its length. A wire twice as long as another will have twice the
resistance, holding all other things constant. The resistance also depends on the reciprocal of the cross-seconal
area of the wire, which in turn depends on the square of the wire’s diameter. A wire with half the diameter of
another will therefore have four mes the resistance, holding all other things constant.
Therefore, the longer a cable is, the more important it is that the wire’s diameter be large. Alternavely, a cable
can have mulple pairs of wires to achieve a larger “eecve wire diameter”. This second approach gives a more
exible cable. For 10  long cables, SynQor recommends that for the UPS-3000 Series:
• The AC INPUT cable have 3 wires (one for the ground) of 8 AWG
• The DC INPUT cable have 6 wires (three for each connecon) of 8 AWG
• The AC OUTPUT cable have 3 wires (one for ground) of 10 AWG
• The DC1 OUTPUT cable have 4 wires (two for each connecon) of 10 AWG
• The DC2 OUTPUT cable have 6 wires (three for each connecon) of 8 AWG
Addional details about the eects of a resistance-related voltage drop are included in “Trouble-Shoong
Guide - Cable wire resistance is too high”.

Section III Operation
Set-Up
The recommended procedure for seng up the UPS is the following:
• Insert the BATTERY PACKs (if not already present) and ghten its screws.
• Make sure the AC BREAKER on the rear panel of the UPS is in the OFF posion.
• Connect the ground wire to the ground stud on the rear panel of the UPS.
• Connect all OUTPUT cables, rst to the UPS and then to the various loads.
• that the oponal DC OUTPUT cables are connected to the UPS and the load with the
correct polarity.
• Connect the USER I/O cables.
• Connect all INPUT cables, rst to the UPS and then to the various sources.
• An overcurrent protect and disconnect device should be installed on the DC INPUT circuit. An
example of a suitable device is a Carling Technologies, F-series, 150 A 125 VDC, FA1-B0-14-
815-12A-BG circuit breaker. (www.carlingtech.com)
•  that the oponal DC INPUT cable is connected to the UPS and the source of DC power
with the correct polarity.
• Turn on the sources (if they have an upstream breaker).
• Move the AC BREAKER on the rear panel of the UPS to the ON posion.
 Be careful to not toggle the ON/OFF switch during the setup. Doing so could cause the UPS
to turn on and present a hazardous voltage at its output.

Section III Operation
Start-Up
•  that all connecons to the UPS are correct.
• If either the AC source or the DC source (or both) is present and within specicaons, the
color of the LED above the ON/OFF switch will be amber. This indicates that the UPS is
in standby mode and ready to turn on. The baery pack LEDs will also be appropriately
illuminated.
• Momentarily push the ON/OFF switch on the front panel of the UPS upward. The switch can
then be released and it will return to its normal (neutral) posion.
• The UPS will immediately enable its outputs (assuming there is no fault condion). The color
of the LED above the ON/OFF switch will change to green. The LEDs on the baery pack will
indicate the amount of power being delivered to the load and the input source from which
this power is being drawn.
 If no input power sources are available the UPS can sll be turned on. It will draw power
from the internal baery for as long as the baery has charge le in it. This is somemes referred
to as a “COLD START” in the industry. Under this condion, the LED above the ON/OFF switch
and the baery pack’s LEDs will inially all be o. When the ON/OFF switch is pushed to the
ON posion, all of these LEDs will be appropriately illuminated. Both baery packs need to be
inserted and charged in order for the cold-start to succeed.
Shut-Down
• Shut down the equipment connected to the UPS.
• Push the ON/OFF switch on the front panel of the UPS downward and hold it in this
posion for 1 second (or more). The color of the LED above the ON/OFF switch will change
to amber (if one or both input power sources are present) or it will be o (if no power
sources are present). The switch can then be released to return to its normal posion. The
service light on the baery will remain green for approximately 10 seconds aer a normal
shutdown
• The UPS will disable its outputs and shut down.
• The baery pack LEDs will either be appropriately illuminated (if one or both input power
sources are present) or they will be o (if no power sources are present).
• It is not necessary to move the AC BREAKER on the rear panel of the UPS to the OFF posion.
