2 GENERAL DESCRIPTION
The 70706 Photomultiplier Power Supplies has been specifically designed by Newport to supply the
highly regulated voltage, which photomultiplier tubes (PMT's) require.
The 70706 is used to supply negative voltages to -2000V and has positive ground.
PMTs and PMT housing are purchased separately.
2.1 FEATURES
Both the 70706 power supply has an LED digital display and two high voltage BNC outputs for
photomultiplier tubes. Since both outputs are on the same power supply, this ensures that two
similar PMT’s can be operated with a minimum of independent drift. This can be critical when one
PMT is monitoring a reference light beam, for instance, while the other is measuring the sample
signal.
A switch and banana jack inputs on the back of the unit enable the high voltage to be switched on
and off by a mechanical circuit breaker. This is a useful feature to protect a powered PMT from
exposure to high light levels by means of micro-switches on sample compartment doors and other
devices. The high voltage can also be switched on and off by a TTL signal and can therefore be
easily controlled by a computer.
Further switch and banana jack inputs on the back of the power supply enable the high voltage to
be controlled by an applied 0 to 9 volt signal instead of the front panel knob. This enables the
supply to be controlled by a computer and DIA converter.

4 PREPARATION FOR USE
4.1 INSPECTION
Upon unpacking the power supply, inspect it for any damage, which may have occurred in transit.
Save all packing materials in case the unit needs to be returned. Visually check to confirm that
there are no broken controls or connectors and that the case and panel surfaces are free from
dents and scratches. If any damage is detected, contact ORIEL.
You should have the following components:
•Photomultiplier Power Supply
•Power Cable
Check that the line voltage (AC power source) is correctly switched for your location. The indicator
is on the back of the unit, in the power receptacle, and will be either 120V or 240V. See Item 2 for
instructions on changing the line voltage selection.
Switch on the power supply and check that the indicator light goes on.
4.2 RE-CONFIGURING THE POWER INPUT MODULE
The power entry module mounted on the rear panel pr0Vides an international IEC receptacle for
power cord attachment. It has 120/240 VAC selection capability and the facility for North American
and European fusing configurations.
This unit has been set at the factory, based on destination, for either 120 VAC/ North American
fused operation or 240 VAC/European operation. Note that two European fuses are required. The
configuration can be easily verified by noting the position of the white indication pin on the power
module.
To change the selected voltage or fuse configuration, unplug the power cord from the unit and pry
off the cover/fuse block assembly with a small blade screwdriver or similar tool.
Use the indicator pin to pull the voltage selector card straight out of the housing. Orient the
indicator pin so that it points in the opposite direction from the desired voltage, as indicated on the
board. Re-insert the board with the voltage indication entering the module first and the pin pointing
out. When the cover is replaced, verify that the pin indicates the correct voltage.
The fuses are mounted on the inside of the cover. The fuse(s) furthest into the housing are the
active set. To change the fuse configuration, loosen the Phillips Head Screw, which holds the fuse
block, by two turns. Lift the fuse block up at the screw end and then slide the block away from the
screw. Invert the block and re-assemble, making sure that the end of the block opposite the screw
is engaged before seating the block at the screw end and re-tightening the screw.
(For operation at 240 VAC, the alternative North American fusing arrangement may be used for
polarized (non reversible) power socket/plug combinations. The fuse should be rated at one half
the original 120V value.)
4.3 INSTALLATION
The power supply is housed in a bench-top enclosure which includes a flip stand to tilt the unit to
facilitate its use.

5 USING THE POWER SUPPLY
5.1 MANUAL CONTROL
•DO NOT CONNECT A PMT TO A POWER SUPPLY WHEN THE SUPPLY IS SWITCHED
ON!!
•Make sure that the Remote Enable switch on the back panel is switched off.
•Make sure that the Output Voltage Control switch on the back panel is switched to Front
Panel.
•Make sure that the supply is switched off and that the voltage control knob is turned all the
way anti-clockwise.
•Connect one or two photomultiplier tubes to the power supply via a (two) high voltage 70097
BNC cable(s).
•Plug in the power cable and switch on.
•CHECK THE MAXIMUM VOLTAGE RATING FOR YOUR PMT!!
•Adjust the high voltage to the PMT with the control knob. The voltage reading will be shown on
the LED display.
< < < WARNING > > >
Make sure the power supply is OFF when connecting or disconnecting any cables to or from the unit.

5.2 EXTERNAL CONTROL
•DO NOT CONNECT A PMT TO A POWER SUPPLY WHEN THE SUPPLY IS SWITCHED
ON!!
•Make sure that the Remote Enable switch on the back panel is switched to Remote.
•Enable/Disable Switch
The high voltage output from the power supply can be switched on or off from an external
source; this is termed disabling the supply.
A simple micro-switch can be used to control the operation of the power supply.
When there is an open circuit between the two input banana jack terminals on the back panel,
the power supply is disabled; when there is a short circuit, the power supply is enabled.
•Computer Control of Enable/Disable Switch
The power supply can be controlled by a computer with a TTL interface.
TTL high will disable the power supply and TTL low will enable the power supply.
•External Voltage Control
A computer with a DIA interface can be used to adjust the output voltage for programmed
control.
Make sure that the Output Voltage Control switch on the back panel is switched to Remote.
The high voltage output from the power supply can be adjusted from an external source. A 0 to
9 volt DC signal applied to the input banana jack terminals on the back panel will control the
output voltage from 0 to -2000 volts. The control voltage to output high voltage ratio is not
precisely 9:2000.
The minimum guaranteed high voltage is 200V at 0V input and the maximum is 2000V at 9V
input, although the actual output voltage may exceed this range. The voltage reading will be
shown on the LED display.
CHECK THE MAXIMUM VOLTAGE RATING FOR YOUR PMT!!

6 TROUBLESHOOTING
6.1 FAULT DIAGNOSIS
If operational problems are encountered, the configuration of the instrumentation should be checked
before the power supply is considered defective. The following list of externally recognizable problems is
provided to assist in this determination.
•No power on indication and meter not illuminated
Check connection to AC supply and fuse(s).
•Output can not be adjusted from the front panel
First, disconnect the load from the high voltage BNC connectors. If this does not alleviate the
problem, check that Remote Enable on rear panel is switched off or, if Remote is elected, that the
binding posts do in fact have a low level TTL signal or a contact closure/short circuit applied. Check
that the rear panel Output Voltage Control is set to the Front Panel position.
•Output can not be adjusted using remote voltage control
Check as above except Output Voltage Control must be set to Remote.
Verify that appropriate control voltage is being applied.
•Remote enable function not effective
Check switch selection on rear panel. Measure control levels at Remote binding posts to be either
TTL (<0.8 VDC low, >2.4 VDC high) or, with contact closure, 0 volts for a low and 5 volts for a high.
Note that the output voltage response to a high level on this control input may require several
seconds for full decay if lightly loaded.
If the above checks have not resolved the problem, contact the Customer Service Department to arrange
for service.
< < < WARNING > > >
POTENTIALLY LETHAL VOLTAGE LEVELS EXIST WITHIN THIS UNIT WHEN POWER IS APPLIED
AND FOR MANY MINUTES AFTER POWER HAS BEEN REMOVED. NEVER REMOVE THE COVE
