PS-1120 POWER SUPPLY OPERATION MANUAL
WARNUNG!
Das Netzteil PS-1120 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!
L'alimentation PS-1120 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 PS-1120 Power Supply produces lethal voltages. Ensure that input power is
disconnected and storage capacitors have been discharged before beginning an
y
inspection or internal adjustment.
WARNING!
The output voltage of the PS-1120 MUST be limited to match the
specifications of those components to which it is connected. Exposing any
system component to voltage (or any other operating condition) that
exceeds its rating can result in damage to the unit and personal injury.
WARNUNG!
Die Ausgangsspannung des Netzteils PS-1120 muss der Leistung aller damit verbundenen
Komponenten angepasst werden. Systemelemente Spannungen (oder anderen
Betriebsbedingungen) auszusetzen, die die Leistungswerte jener Komponenten übertreffen, ist
gefährlich und kann zu Schäden und Verletzungen führen.
ATTENTION!
Il faut que la tension fournie par l'alimentation PS-1120 soit limitée aux caractéristiques des composants
auxquels il sera mis en contact. En exposant un composant quelconque à une tension (ou à d'autres
conditions de fonctionnement), qui en dépasse la limite on pourrait endommager l'appareil ou provoquer
des blessures.
WARNING!
The PS-1120 Power Supply is capable of producing 20 watts of output power.
Heatsinking of metal-can flashlamps and Lite-Pacs is required when these devices are
operated above 25 watts.
WARNUNG!
Das Netzteil PS-1120 erzeugt bis zu 20 Watt Ausgang. Bei Leistungen höher als 25 Watt müssen
Dosenlampe sowie Triggermodul, mittels eines Kühlblechs, abgekühlt werden.
ATTENTION!
L'alimentation PS-1120 fournit jusqu' à 20 watt de puissance débitée. Quand une lampe à boite en
métal et un déclenchement fonctionnent au dessus de 25 watt, il faut les refroidir au moyen d'une
source froide.

PS-1120 POWER SUPPLY OPERATION MANUAL
1.0 INTRODUCTION
1.1 DESCRIPTION
The PS-1120 POWER SUPPLY is one of a series of Power Supplies designed
for high energy capacitor discharge service with any guided arc bulb-type
flashlamp and Lite-Pac® including those shown below.
Figure 1. Optional PerkinElmer Lite-Pacs and Accessories
The PS-1120 Power Supply performs two functions: (1) charges the flashlamp
discharge capacitor to a specific voltage at a specified rate, and (2) provides
trigger capacitor charging and switching functions at the required flash rate. Its
well regulated, low ripple characteristics ensure excellent discharge repeatability.
1.2 UNPACKING
If the condition of the outer packaging suggests mishandling has occurred,
examine the unit 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.

4.0 OPERATING CONDITIONS
4.1 ENERGY RELATIONSHIPS
At 24V input, 600V output, the unit delivers a minimum of 20 joules per second to
the discharge capacitor. Figure 3.1 shows typical charge rate values vs output
voltage for four different DC inputs.
Figure 3. PS-1120 Typical Charge Rate Curves.
The energy per discharge is given by the expression:
J = Discharge energy
C = Discharge capacitance
V = Output voltage
Power is determined by P= J x Flashrate
Long-term (1 minute or more) average
power must be limited to 20 watts.
Therefore, the sum total of the
accumulated energy discharges
(Joules) divided by the operating
period (seconds) must be ≤20 watts.
The flashtube may be fired any time
after the charge time (see Fig. 4).

5.0 OPERATION
Once operating conditions have been determined, proceed as follows:
5.1 TRIGGER REQUIREMENTS
Move the trigger switch to the EXT position
(See Figure 2). Triggering is accomplished
by connecting J1-5 to +5V and J1-4 to
ground. Other logic voltages may be
accommodated by including a series
resistor. See specifications (Section 2)
for additional information.
Figure 5. Input Trigger Circuit
The PS-1120 can be tested for proper Operation by moving the TRIGGER switch
to the INT position. The unit should now flash at a low rate.
5.2 INTERNAL ADJUSTMENT OF HV OUTPUT REFERENCE VOLTAGE
The output voltage is programmed from 400V to 1KV by varying the VREF input
from 4.0 to 10.0 volts. The adjustment pot, VOUT, is available through a hole in
the J1 input panel (see Figure 2). The VREF switch must be in the INT position,
as shipped from the factory.
5.3 EXTERNAL ADJUSTMENT OF HV OUTPUT REFERENCE VOLTAGE
Move the VREF switch to the EXT position (See Figure 2). Program the output
voltage from 400V to 1KV by varying the VREF from 4.0 to 10.0 volts.
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.

5.4 INTERCONNECTIONS
1. Make input connections according to Figure 7
and 9 or 10 (whichever is appropriate).
2. Make output connections according to Figure 8
and 9 or 10. When using a standard wiring
Lite-Pac, twist together the brown and white
Lite-Pac trigger leads and connect them to the
appropriate terminals on the output panel.
3. Add external capacitor(s) and trigger diode, if
required, to the Lite-Pac discharge circuit.
4. Turn on the power supply.
5. Set the high voltage by adjusting the reference
voltage.

PS-1120 POWER SUPPLY OPERATION MANUAL
6.0 MAINTENANCE
6.1 REPAIRS
The PS-1120 Power Supply is, generally speaking, a trouble-free unit. No
routine maintenance or repair is required.
The power supply is protected by a 7A slo-blow fuse in one leg of the DC input.
If this fuse opens, do not replace it. Return the unit to the factory for repair.
In the event that the unit fails or does not function properly, 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.
6.2 REPACKING AND STORAGE
If the PS-1120 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 packaged 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).
WARNING!
The PS-1120 output voltage MUST be limited to match the
specifications of those components to which it is
connected. Exposing any system component to voltage (or
any other operating condition) that exceeds its rating can
result in damage to the unit and personal injury.
