LS-1130 FLASHPAC OPERATION MANUAL
WARNUNG!
Das LS-1130 erzeugt lebensgefährliche Spannungen. Es muss deshalb darauf geachtet werden, dass
der ankommende Strom ausgeschaltet ist und die Ladekondensatoren entladen sind, bevor Kontrollen
oder Regelungen am Gerät unternommen werden!
ATTENTION!
Le LS-1130 fournit des tensions dangereuses. Veuillez vérifier que la prise de courant es
t
déconnectée et les condensateurs d'accumulation sont déchargés avant d'entreprendre des
inspections ou des réglages sur l'appareil.
WARNING!
The LS-1130 produces lethal voltages. Ensure that input power is disconnected and
storage capacitors have been discharged before beginning any inspection or internal
adjustment.
WARNING!
The normal operation of the product involves high voltages which are
potentially lethal.
Because this product is only one component of a system, and, once sold is exclusively under the control
of the user, it has the potential of being used in a manner outside the intended purpose of Excelitas
Technologies design.
It is essential that the operating specifications and parameters described in Excelitas Technologies
literature and those accompanying other manufacturer's components be observed and not be exceeded
under any conditions.
To install or operate this product in a manner for which it is not intended may cause personal injury or
death, as well as severe damage to the product and/or other system components.

LS-1130 FLASHPAC OPERATION MANUAL
1. INTRODUCTION
1.1. DESCRIPTION
The LS-1130 FlashPac is an integrated light system that requires only external
power and control connections for operation. Its internal circuitry provides power to
the discharge capacitor as well as output voltage control and triggering.
The standard fiber-optic cable adapter accepts 1.00" diameter (nominal) sub-
adapters such as the MVS-14-2 or MVS-20 to accept various cable configurations
(see Table 5). Please consult the factory regarding other custom options.
1.2. UNPACKING
If the condition of the outer packaging suggests mishandling has occurred, examine
the LS-1130 for any signs of breakage during shipment. If there are any obvious
signs of damage, contact the carrier immediately and do not proceed with the
installation. It is recommended that the packaging material be retained and stored in
the event that the unit has to be reshipped.
2. INSTALLATION
2.1. MOUNTING (SEE FIGURE 1)
Mount the unit in a protected position, without restricting air flow through its
ventilation openings, by using two #6 clearance holes in the base of the enclosure.
Mounting hardware is user-supplied.
2.2. SAFETY REQUIREMENTS
Use Input Receptacle, J1 (on the right) as a disconnect
device to remove any possibility of electrical input,
particularly, when accessing the unit’s interior. Orient the unit
so that J1 is accessible.
Protect the usit by coneecting user’s ground to pin 8 of
Input Receptacle, J1.
Be careful not to touch the strobe output window, which gets very hot.
The window will break if treated in a manner inappropriate for glass.

LS-1130 FLASHPAC OPERATION MANUAL
4. OPERATING CONDITIONS
4.1. POWER CONVERSION METHOD
The LS-1130 uses a high frequency inductive storage, energy release (flyback)
charging system. Output voltage level control is maintained by sensing through a
HV divider to a reference, difference amplifier. The difference amplifier controls the
number of energy cycles released to the storage capacitor in accordance with the
variable reference voltage (Vref) applied to the input.
4.2. ENERGY RELEATIONSHIPS
The storage capacitor recovery or
charge time is shown in Figure 2 for
various DC inputs. When operating at
pulse frequencies above 100Hz, add
0.2mSec (holdoff) to the charge time.
The energy per discharge is given by
the expression:
J = ½CV2, where: Figure 2. Charge Time Curves
C = the discharge capacitor in microfarads (μF)
V = the voltage across C in kilovolts (KV)
J = the discharge energy in joules (J)
Long-term (1 minute or more)
average power must be limited to
20 watts. Therefore, the
accumulated energy discharges
(joules) divided by the operating
period (seconds) must be 20
watts.
The flashtube may be fired any
time after charge time (t) (see
Figure 3). Figure 3. Output Voltage vs. Time

5. OPERATION
Once operating conditions have been determined, proceed as follows.
5.1. TRIGGER REQUIREMENTS
Triggering is accomplished by
connecting J1-5 to +5V and sinking J1-4
to ground. Other logic voltages may be
accommodated by including a series
resistor. See specifications (Section 3)
for additional information. Figure 4. Input Trigger Circuit
5.2. INTERNAL ADJUSTMENT OF HV REFERENCE VOLTAGE
The output voltage level of the LS-1130 is controlled by a reference voltage (Vref)
which may be generated internally or applied externally. The internal/external mode
is determined by the position of jumper JP1 on the unit's printed circuit module.
When the unit is configured to use the internal reference voltage, output voltage can
be adjusted over its full 400-1KV range via a potentiometer (RV1) which is accessed
through a hole in the input panel (see Figure 1). All units are shipped with JP1 in the
INTERNAL position and adjusted for 600VDC.
5.3. EXTERNAL ADJUSTMENT OF HV REFERENCE VOLTAGE
To configure the LS-1130 for external HV adjustment:
1. Make sure the unit is off.
2. Open the cover by removing its mounting screws.
3. Move jumper JP1 to the EXT position.
4. Close the cover and replace the screws.
5. Rotate the internal voltage reference adjustment control (RV1) fully clockwise.
(RV1 is available through a hole in the input panel).
The output HV is programmed from 400V to 1KV by varying the Vref Power Supply
from 4.0 to 10.0 volts.

LS-1130 FLASHPAC OPERATION MANUAL
A typical external adjustment diagram is shown in Figure 5. The reference supply may be
the output of a DA Converter or simply a divider network from the source power supply.
The LS-1130 internal reference adjustment control (RV1) must be set fully clockwise for full
range output.
The Vref power supply may be programmed to zero, with the HV output (V) dropping to less
than 60V. Note that the power and Vref returns are connected internally.

6. MAINTENANCE
6.1. REPAIRS
The LS-1130 FlashPac strobe is, generally speaking, a trouble-free unit. No routine
maintenance or repair is required, except for replacement of the flashlamp.
The unit is protected by a 4A slo-blow fuse. If this fuse opens, do not replace it.
Return it to the factory for repair.
In the event that the unit fails or does not function properly (other than flashlamp
failure), it is strongly suggested that no attempt be made to troubleshoot. Field
repairs or customer modifications are not authorized, and, if attempted, will void the
warranty. Repairs must be made only by factory-trained personnel. Return the unit
to Excelitas Technologies.
6.2. FLASHLAMP REPLACEMENT
Over a period of time (depending on
usage), the xenon flashlamp may
gradually deteriorate and have to be
replaced.
To replace the flashlamp, proceed as follows:
1. Ensure that input power is removed from the unit.
2. Loosen the optical connector (heatsink) adjustment screw.
3. Pull the nose piece out from under the optical connector.
4. Loosen and remove two mounting screws and remove the optical connector.
5. Grasp the defective flashlamp, pull it straight out of the Lite-Pac, and discard
it.
6. Line up the leads of a new flashlamp with the corresponding holes in the Lite-
Pac and push the flashlamp until it is fully seated.
7. Replace the optical connector, screws and nosepiece over the new flashlamp
in reverse order to that above and tighten the hardware.
6.3. REPACKING AND STORAGE
If the LS-1130 is to be stored for a prolonged period, shipped to another location, or
returned to the factory for repair, it should be repacked in the original packaging
material. If the packaging material has been discarded, the unit should be put in a
suitable container with sufficient protective material to ensure that the unit cannot
move within the package and is protected from damage that could occur from
improper handling.
Any storage area used for the unit should be dry, at a temperature of -40F to
+194F (-40C to +90C).
high-pressure, gas filled device. Wear
Safety glasses when replacing it.
