INTRODUCTION
1.1 THE XP SERIES UNINTERRUPTIBLE POWER SUPPLY
AlphaXPSeriesUninterruptiblePowerSupplies(UPS)aredesignedforpowering
signalprocessingequipmentinCableTelevisionand Broadband LAN distribution systems.
The power supply, which consists of an XM Series Power Module and a pole or ground-
mount enclosure, provides the critical load with current-limited, regulated AC power that is
free from disturbances such as spikes, surges, brownouts or blackouts. Backup power is
achievedbyasetofrechargeable,gelledelectrolyte(nomaintenance)batteries.
During LINE operation, AC power enters the module where it is converted to a "quasi"
square wave and regulated (at the required output voltage). It is then passed onto the load
via the SPI (Service Power Inserter) located inside the power supply enclosure. At the
same time, power is directed to the battery charger to maintain a float charge to the
batteries.
When the incoming AC line voltage drops significantly, or a utility power outage
occurs, the XM Series power module automatically transfers to inverter (STANDBY)
operationinorderto maintain power to the load. During the transfer, energy contained in
themodule'sferroresonant transformercontinuestosupplypowertothe output. Depending
upon the type of batteries used, and the loading on the power supply, backup power can
continue for several hours. When utility line power returns, the XM Series power module
waits momentarily for the utility voltage and frequency to stabilize and then initiates a
smooth, in-phase transfer back to AC line power. Once the transfer is complete, the
battery charger quickly recharges the batteries in preparation for the next utility power
outage.
The XP Series Uninterruptible Power Supply contains an impressive list of features
including an "OUTPUT CURRENT" display to indicate output current to the load; a
"CHARGER STATUS" block to display the various battery charging modes; a "SYSTEM
STATUS" block to display LINE and STANDBY operation, plus indicate acceptable AC
output power; an output fuse to protect against excessive short circuit currents; and a
battery circuit breaker to protect the DC circuit. Optional features can include a
"STANDBY DATA" display to indicate "total outage time" and "number of standby events;"
an APM (Automatic Performance Monitor) to self-test the inverter and batteries at regular
intervals; and a USM (Universal Status Monitor) plug-in logic upgrade to facilitate status
monitoring.
UL Recognized and CSA Approved, the XP Series Uninterruptible Power Supply is
designed to be one of the most rugged, reliable, and versatile power supplies available.
Alpha Technologies, recognized as an international market leader in the field of backup
power, offers complete technical support and prompt, reliable service to ensure that your
powersupplycontinuestoprovideyearsoftrouble-freeoperation.

1.2 Theory of Operation
The XP Series Uninterruptible Power Supply consists of an XM Series power module,
apoleorground-mountenclosure,andasetofgelledelectrolyte,no maintenance batter-
ies. Thepowermodule containsaferroresonanttransformer, resonantcapacitor,dual-
modetemperature-compensatedbatterycharger,DCtoACconverter(inverter),transfer/
isolation relay, and a main circuit module assembly containing the logic circuit.
1.2.1 AC(LINE)Operation
During AC LINE operation, utility power is routed into the primary winding of
ferroresonant transformer T1 and through the contacts of the transfer / isolation relay K101.
At the same time, power is directed to the auxiliary transformer T101 which provides power
for the control circuitry. A charger / inverter winding on transformer T1 supplies the battery
charger circuit. AC capacitor C1 forms the resonant circuit of ferroresonant transformer T1
which provides excellent noise and spike attenuation, short circuit current limiting, and
outputvoltageregulation. Theferroresonanttransformer producesa"quasi"squarewave
outputwhichresemblesaroundedsquarewave.
NOTE:WHENMEASURINGTHEOUTPUTVOLTAGEOFFERRORESONANT
TRANSFORMERS,USE ONLY A TRUE RMS AC VOLTMETER. NON-RMS READING
METERS ARE CALIBRATED TO RESPOND TO PURE SINE WAVES AND WILL NOT
PROVIDE AN ACCURATE READING WHEN MEASURING A "QUASI" SQUARE WAVE
OUTPUT.

1. INTRODUCTION
1.2 Theory of Operation, continued
1.2.2 Inverter(STANDBY)Operation
When the incoming AC line voltage drops significantly, or a complete power outage
occurs, the control logic’s line monitor activates STANDBY operation. The battery pow-
ered inverter comes on-line (in-phase with the failing AC line) as the transfer / isolation
relay switches to prevent AC power from back-feeding to the utility. During the brief
transferfromLINEto STANDBY operation,theenergycontainedin theferro-resonant
transformer continues to supply power to the load. The following changes occur: The
transfer / isolation relay K101 opens to disconnect the AC line from the primary winding of
ferroresonant transformer T1. The control logic drives the inverter transistors on and off at
line frequency. This switching action converts the DC battery current into AC in the
inverterwindingoftheferroresonanttransformerwhichprovidesregulatedpowertothe
load. The control logic, which includes a circuit to protect the inverter transistors from
over-currentdamage,monitorstheconditionofthebatteriesduringinverteroperation.
Sincea prolonged AC line outage would severely discharge thebatteries, resulting in
permanentdamage,thecontrollogicdisablestheinverterwhenthebatteriesdropto
approximately 10.5 VDC / battery (31.5 VDC / set).
WhenAC line voltage returns, the power module transfers backto LINE operation
within 10 to 50 seconds. This delay allows the AC line voltage and frequency to stabilize
before the control logic phase-locks the inverter’s output to the utility input. It then de-
energizes the transfer / isolation relay, re-connects the AC line to the primary of the
ferroresonant transformer and disconnects the batteries from the inverter. This results in a
smooth, in-phase transfer back to utility power without interruption of service to the load.
The battery charging circuit is then activated to recharge the batteries in preparation for the
nextpoweroutage.
1.2.3 ChargerOperation
TheXPSeriesUninterruptiblePowerSupplyusesadual-mode,temperature-compen-
satedbatterycharger. DuringAClineoperation,acharger/inverterwindingon
ferroresonanttransformerT1feedsthechargercircuitwhichprovides"float"and"equalize"
charge voltages to the batteries. The circuit consists of a switching regulator, inductor L1
andotherassociated components. Thecharger(inverter)winding oftransformerT1
produces an AC voltage that is regulated by SCRs Q301, Q302 and filtered by inductor L1.
Thisproduces a regulated DC battery charging voltage. The charge current passes
through R104 to provide current-limit sensing for the charging circuit. Fuse F301, located
on the removable, Main Circuit Module assembly, protects the circuit in the event of
chargermalfunctionorreversalofthebatteryleads(Refertothecomponentlayoutdrawing
at the back of the manual).
Thestandardcontrollogicprovidesaconstant(programmable) float charge to the
batteries. A switch (CHARGE MODE) SW201 located on the front panel of the power
module allows a technician to manually activate the charger’s equalize mode which has a
1.2 hour duration. With the optional APM or USM logic upgrade installed, the equalize
chargingmodebecomesanautomaticuser-programmablefunction.
WhentheXMSeriesmoduleresumesLINEoperation,thechargerquicklyrecharges
the batteries. The charge current is determined by the acceptance level of the batteries,
but limited to 10 Amps maximum. As the batteries approach full charge, the charger’s
current tapers off to normal float levels.

"CHECK BATTERIES" or red "CHECK INVERTER" LEDs in the APM status block will
flash to indicate the circuit that has failed. At the same time, the external LRI option on
the enclosure will flash to signal that maintenance is required. The APM self-test feature
is a great aid when trouble-shooting the power supply and can be manually activated by
pressing the "TEST/RESET" switch. The yellow "TEST IN PROGRESS" LED will light as
the power supply transfers into self-test mode. The red "STANDBY POWER" LED in the
SYSTEM STATUS block will come ON to indicate that the power supply is in inverter
operation. Since self-test only simulates an outage, the green "LINE POWER" LED will
remain ON, indicating that utility power is still available. If a fault is detected, the power
supply will transfer back to line power without interruption to the output.
2.1.1 "TEST/RESET"Switch
The "TEST/RESET" switch is standard on all XM Series power modules, but functional
only on units equipped with APM or USM logic upgrades. It is used to manually cycle the
power supply in and out of self-test mode, and to reset alarms. If a fault is detected during
the APM self-test mode, the "TEST/RESET" switch resets the enclosure’s flashing LRI
(Local and Remote Indicator) and the SSR (Standby Status Relay) alarms; however, the
red "CHECK BATTERIES" and "CHECK INVERTER" LEDs cannot be reset until the fault
is corrected.
2.1.2 "NOTINSTALLED"(green)LED
On units not equipped with an APM logic upgrade, the green "NOT INSTALLED" LED
will light whenever the "TEST/RESET" switch is pressed.
2.1.3 "TEST IN PROGRESS" (yellow) LED
The yellow "TEST IN PROGRESS" LED indicates that the power supply is in self-test
mode.
2.1.4 "CHECKBATTERIES"(red)LED
If the red "CHECK BATTERIES" LED is flashing, it indicates that one or more of the
batteries are unable to carry the load and that maintenance is required. The flashing LED
cannot be reset until the fault is corrected. NOTE: Under this condition, the power supply
willnot be able to support inverter operation.
2.1.5 "CHECKINVERTER"(red)LED
If the red "CHECK INVERTER" LED is flashing, it indicates that the inverter has failed
to produce AC and that maintenance is required. The flashing LED cannot be reset until
the fault is corrected. NOTE: Under this condition, the power supply will not be able to
supportinverteroperation.

2.2 Charger Status Block
TheXMSeriespowermoduleisequippedwithadualmode,temperature-compensated
battery charger. The "CHARGER STATUS" block is broken into categories to reflect the
differentchargingmodes:
2.2.1 "CHARGEMODE"Switch
The "CHARGE MODE" switch is used to manually sequence the battery charger
through float and equalize modes. On non-APM units, equalize can only be initiated by
pressing the "CHARGE MODE" switch. Equalize is an automatic feature on units
equippedwithAPMandUSM logic upgrades.
2.2.2 "FLOAT"(green)LED
The green "FLOAT" LED indicates that the battery charger is delivering a float charge
to the batteries.
2.2.3 "EQUALIZE"(yellow)LED
The yellow "EQUALIZE" LED indicates that the battery charger is delivering an
equalize charge to the batteries. On units equipped with standard logic, equalize can only
be activated manually and lasts for approximately 1.2 hours. On units equipped with APM
orUSMlogicupgrades,equalizecanbeactivatedeitherautomatically(pre-selected
durationandinterval)ormanually.
2.2.4 "RECHARGE"(red)LED
The red "RECHARGE" LED indicates that the batteries are drawing more than 5 Amps
of current from the charger. The charge current is determined by the acceptance level of
the batteries, but limited to 10 Amps maximum. As the batteries approach full charge, the
charger’s current tapers off to normal float. The red LED is ON only when the charge
current exceeds 5 Amps in either float or equalize modes.

2.3 System Status Block
The "SYSTEM STATUS" block is broken into three categories to quickly identify the
powersupply'soperational status:runningonAClinepower;runningonbatteries;and
nominaloutputpowertothe load.
2.3.1 "LINEPOWER"(green)LED
The green "LINE POWER" LED indicates that power from the utility is present and that
the power supply is operating in AC LINE mode.
2.3.2 "STANDBYPOWER"(red)LED
The red "STANDBY POWER" LED indicates that the power supply is operating from
its battery backup. When AC from the utility is lost, the green "LINE POWER" LED goes
OFF and the red "STANDBY POWER" LED comes ON as the unit transfers to inverter
operation. Whenever the red LED is ON, the unit is running on backup power.
2.3.3 "ACOUTPUT"(green)LED
The green "AC OUTPUT" LED indicates that acceptable voltage is available at the
power module's output. Regardless of the input mode, "LINE POWER" or "STANDBY
POWER," the "AC OUTPUT" LED should remain ON at all times.

2.4 Output Current Display
The amount of current from the power supply to the load is indicated by the "OUTPUT
CURRENT" display. The LED display is useful for determining the overall status of the
load. When there is no load connected, the LEDs on the display will be OFF. In situations
where LEDs light above the rated output of the power supply, such as 18 or 20 Amps, an
overload or short circuit condition exists in the load.
2.4.1 LEDDisplay
The LEDs are set in 2 Amp increments from 2 to 20 Amps; however, the display is
accurate to 1 Amp. When the output current falls between increments, both adjacent LEDs
light.

2.5 Standby Data Display (SDD)
The optional, dual-function LED "STANDBY DATA" display is used to keep track of
accumulated inverter run time, and to record the number of standby events that have
occurred. The "ELAPSED TIME" clock is activated only when the power supply is in
inverter mode. Elapsed time will continue to accumulate until the clock is reset. The
"STANDBY EVENTS" counter displays the number of standby events that have lasted
longer than 60 seconds duration. Standby events will continue to accumulate until the
counter is reset. The SDD is equipped with an on-board battery to maintain data even
whenthe main circuit module is completely removed or acomplete power outage (including
low battery shutdown) occurs .
2.5.1 "MODE"Switch
The "MODE" switch activates the display and verifies the mode of operation. When
the switch is pressed, the "ELAPSED TIME" LED will light (or "STANDBY EVENTS" LED
dependinguponthe mode). At the same time, the corresponding information will appear in
the "TIME/EVENTS" window for approximately 10 seconds. The next mode is activated
by pressing the switch again. "ELAPSED TIME" and "STANDBY EVENT" information can
be toggled by briefly pressing the "MODE" switch.
NOTE: To clear either the "ELAPSED TIME" or "STANDBY EVENT" memory, select
the desired mode. Press and hold the "MODE" switch until the LED flashes. Then, press
the MODE switch twice (in rapid succession). A single decimal point will appear in the
displaywhenthememoryhasbeencleared.
2.5.2 "ELAPSED TIME" LED
The "ELAPSED TIME" LED indicates the mode as the "TIME/EVENTS" window
displays the time accumulated during inverter operation. The clock, which displays time to
the nearest 0.1 hours, will continue to accumulate time until the memory is manually
cleared.
2.5.3 "STANDBYEVENTS"LED
The "STANDBY EVENTS" LED indicates the mode as the "TIME/EVENTS" window
displays standby events that have lasted more than 60 seconds in duration. The counter
will continue to register standby events until the memory is manually cleared.
2.5.4 "TIME/EVENTS"Window
The "TIME/EVENTS" window displays "ELAPSED TIME" in 0.1 hr increments, up to
999.9. "STANDBY EVENTS" are displayed in increments of 1, up to 9999.
