1. General Description
1.1 Intended Applications
The 37&110BA-2 is a high quality, rugged, 400Hz IN 60Hz OUT, 1kW / 2KVA, 19” rack-mounted
8Qinterruptible Power Source (UPS). In addition to full compliance with all the requirements of MIL-
STD-1399 (Section 300), the 37&110BA-2 is specifically designed to meet the harsh military ship
ERDUGenvironment. The high reliability and ruggedness of the 37&110BA-2 make it an excellent
FKRLFHQRWonly for military shipboard applications, but for tactical shore-based applications as well.
1.2 Functional Overview
The 37&110BA-2 consists of two main sections: Power Conditioner and UPS (see Fig. 1).
The Power Conditioner is a 400Hz isolation transformer (with RFI filters and spike absorbers).
In addition to 115Vac to the UPS section, the isolation transformer provides a low voltage for the
24Vdc contactor supply. When AC input drops, the 24Vdc is provided from battery power. The
Power Conditioner contains internal fuses on its input. These internal fuses are intended only as a
safety feature in case of an internal failure.
The UPS is composed of a high power factor AC-DC Converter, a Removable Battery Pack, a
Battery Charger, a DC-AC Inverter and a microcontroller-based Control Circuit.
The AC-DC Converter is a high frequency switching converter that provides 320VDC to the DC-AC
inverter. The AC-DC converter draws clean sine input current waveform and does not induce
electrical noise into the input lines.
The Removable Battery Pack contains the energy source used by the UPS to provide power during
AC input failures. The Battery Pack includes eight 12V / 5AH lead-acid, sealed, maintenance-free
type cells. It provides 10 minutes of full rated output power. The Battery Pack is not a serviceable
item. It cannot be disassembled, and can only be replaced as a single unit.
The Battery Charger is a high frequency, voltage-regulated and current-limited DC to DC converter.
It is powered from the 320VDC output of the AC-DC Input Converter and provides temperature-
compensated float charge to the Battery Pack.
The DC-AC Inverter is a high frequency inverter that generates a clean sine-shape 60Hz, 115VAC
voltage from the 320VDC output of the AC to DC Input Section. The DC-AC Inverter is current-
limited and has an overload protection circuit that turns it off (latched) after a delay from the time
the load exceeds 120%. The delay depends upon the overload level.
The Control Circuit is a microcontroller-based circuit that provides monitoring of the unit’s status
(battery charge, load level, input and output levels, etc.) and supports communications and front
panel status indicators.

6. Operation, Controls and Indicators (ref. Figures 3 and 4)
6.1 Turning the UPS ON and OFF
In order to turn the UPS ON (after the electrical connections are made), turn ON the Input ON/OFF
switch (4), the Master ON/OFF switch (5) and if used, the remote ON/OFF switch. (The order is not
important). If remote ON/OFF is not used, the connections of J5 (described in paragraph 8.3)
should be installed before the unit is turned on.
When the Master ON/OFF switch (5) or the remote ON/OFF switch are turned off, the internal
contactors open and disconnect both the input and the output of the UPS and it turns OFF.
When the UPS operates, turning off the Input ON/OFF switch (4) disconnects the UPS from the AC
input, and the UPS then runs on battery power only.
To turn the UPS off, the Master ON/OFF switch or the remote ON/OFF switch must be in the OFF
position. (It will automatically disconnect the input connector too).
Note: The UPS will not start on battery power (to avoid battery discharge during shipping and
storage). Hence, the Input ON/OFF switch must be ON and AC voltage must be present at the input
in order to start the UPS.
When a remote control of the UPS is desired, the Input ON/OFF and the Master ON/OFF switches
on the front panel should be both in the ON position. Turning the remote ON/OFF switch ON and
OFF will turn the UPS ON and OFF. (Please see paragraph 8.3).
6.2 Visual Indicators
6.2.1 Normal Operation
When the UPS is running on AC input power and both Master and Input switches are ON, the two
bar graphs (17, 18), the green Input OK LED (7) and the green Output OK LED (9) are on.
The Load Level Bar Graph (17) indicates the loading percentage of the UPS. 100% load is equal to
1000W of output power. The lower six positions of the Load Level Bar Graph (15% to 75%) are
green. The next three positions (80%, 110%, 120%) are orange and the two uppermost positions
(130% and 140%) are red. The colors do not have any special significance and are only intended to
assist fast scanning of the load level.
The Battery Charge Bar Graph (18) indicates the percentage charge level of the battery. 100%
signifies that at least 10 minutes of full load will be supported by the battery, 50% signifies
5 minutes at full load and so on. Lower loads result in longer expected battery operation time.
When the battery is being charged, the uppermost active segment of the Battery Charge Bar Graph
blinks to indicate that charging is on.
6.2.2 Standby Mode
When the yellow Output Standby LED (8) is on, the UPS is in the Standby Mode. In this Mode the
DC-AC inverter is OFF and the output contactor is open, but all other function of the UPS are active
(including battery charging and RS-232 communication port). The UPS reaches this mode when
command by the RS-232 or the “dry relays” into this mode.

6.3 Battery Test
Battery Test may be invoked only if the UPS runs on AC input power, the Battery Charge level is
above 85%, the load is above 35% and the battery is not engaged in supporting Input Power Limit.
If Battery Test is denied due to low charge level, the Charge Level Bar Graph blinks once when the
Battery Test Push-button is pressed.
To test the battery, press momentarily on the Battery Test Push-button (21). The green Battery Test
Passed LED (20) will blink for about 3 seconds (indicating that Battery Test is running). After about
3 seconds, either the red Battery Test Failed LED (22) will turn on (and latch), indicating a bad
battery, or the green Battery Test Passed LED (20) will turn on for about 20 seconds, indicating that
battery successfully passed the test.
The Battery Test may be repeated only after at least 20 seconds have elapsed since the last test.
7. Taking Care of the Battery
7.1 Battery Service Life
The gel lead-acid, sealed and maintenance-free battery used in the PTC-110BA-2 is of the highest
quality. Nevertheless, it is a Limited Life Item, and its life expectancy depends upon its operating
and storage conditions.
The three most important factors that determine the life of the battery are:
Temperature
Storage Conditions
Charge-Discharge Cycles
Temperature
The battery used in the PTC-0110BA-2 is sealed and does not “dry up” or lose gasses, but its end of
service life is brought about by the gradual corrosion of the electrodes. This process is
accelerated by high operating temperatures. Every 10°C rise above 20°C will reduce the battery
service life by half.
Storage Conditions
When lead-acid batteries are stored for extended periods of time, lead sulfate is formed on the
negative plates and insulates them.
The sulfating rate depends on the ambient temperature and the charge level of the battery. High
temperature and low charge level accelerate the sulfating and reduce the battery life.
In order to protect your battery from damage during storage:
• Make sure the battery is fully charged periodically (every 4 months if the temperature is
approximately 24°C, and every two months if the temperature is higher than 37°C) by operating
the UPS for at least four hours.
• Store the batteries in a cool place (may be stored separately from the UPS).
• Never store a discharged battery !!!

37&3URGXFWLRQ7UDGLQJ&R$* PTC-0110BA2UM, REV(A)
10
Charge-discharge Cycles
The number of times and the depth of battery discharges (during AC input failure) affects the
service life of the battery.
If the battery is allowed to discharge only to 50% of its charge, the number of charge-discharge
cycles (before it fails) will be three times the number of cycles had it been allowed to reach 30%
charge.
Battery life may be prolonged by limiting the operating time on battery power to the minimum
required by the system to perform an orderly shutdown.
7.2 Replacing the Battery Pack
For ease of use, the battery of the PTC-0110BA-2 is packaged within a Removable Battery Pack
(P/N M357380) that may be ordered separately.
During storage, the Battery Pack may be removed and stored separately in a cooled ambient.
To remove the Battery Pack from the UPS:
a) Turn OFF the Master ON/OFF switches.
b) Disconnect J1 and J2 from the rear panel.
c) Open seven screws on the battery’s rear cover.
d) Open the Battery Connector access cover. Remove screws.
e) Disconnect the connector by pulling upward.
f) Unscrew the right battery’s screws on the top and three screws on the right side
of the UPS (marked by a B” on the top and recessed on the side).
g) Hold the Battery Pack by the two edges on the sides (Caution: Two-man lift !!) and
lift it straight up.
To install a new battery:
a) Lower the Battery Pack straight into its place (at the right side of the UPS). Verify that
the battery mating connector and harness (near the front panel) are not
damaged by the battery.
b) Install the screws on the top and the right side without tightening them yet. After all
screws are in, torque them at 11 IN.LB for the #6 top screws and 22 IN.LB for the #8
side screws. Note: Suitable locking compound (Locktite 242, or similar) should be
applied to all screws.
c) Connect the battery connector.
d) Close the battery connector cover and tighten its screws (6.5 IN.LB).
e) Close the battery’s rear cover and tighten its screws (6.5 IN.LB).
f) Reconnect J1 and J2 to the rear panel.
The unit is now ready for operation.
Note: If the new battery is fully charged, press the Set-Battery-Charge-to-100%
Push-Button for ten seconds to set the charge level to full scale.

8.3 Remote ON/OFF Interface J5
Important note: The PTC-0110BA-2 is shipped with a matting connector plugged into J5, with a
jumper that enables the unit. If remote ON/OFF is not desired, do not remove it.
The remote ON/OFF Interface J5 provides a mean for turning the UPS ON and OFF by a remote
panel switch. When pin 8 or 15 of J5 are connected to pin 7 or 14 of J5 (8 is internally connected to
15 and 7 is internally connected to 14) the UPS is enabled. It will be ON only if the Master ON/OFF is
also ON. When pins 8 and 15 are not connected (externally) to pins 7 or 14 the UPS will be OFF
regardless of the position of the switches on the front panel.
To control the UPS by the remote switch, leave the front panel switches in the ON position and turn
the UPS ON and OFF by closing (ON) and opening (OFF) the remote switch.

When test mode is invoked by pressing the push-button on the front panel,
the UPS performs battery impedance testing without interrupting the output
power (even if the battery fails) utilizing a proprietary time-sharing circuit.
The test results are displayed on panel indicators.
End-to-End testing of the UPS is accomplished by cycling the INPUT
ON/OFF switch on the front panel.
The UPS will beep when it operates on battery power or during over-
temperature condition. The alarm may be silenced by pressing the "Alarm
Off" push-button on the front panel.
The PTC-0110BA-2 has two double-pole contactors, one on the input and
one on the output.
The input ON/OFF contactor is controlled by the input ON/OFF switch
located on the front panel.
The Master ON/OFF switch, located on the front panel, shuts down the UPS
and opens both input and output contactors when in the OFF position.
When the two ON/OFF pins are opened the UPS will turn OFF and the
input and output contactors will open. When the two lines are shorted
together the front panel switches determine the status. (The UPS is supplied
with a mating connector and a jumper between the two ON/OFF pins).
