Safety Precautions:
WARNING!
Read and fully understand these instructions before
applying power to this unit.
Never operate this equipment without first providing a good earth ground
connected to the ground stud located below the HV connector. The ground
wire of the input power connection must also be properly grounded.
Voltages used in and the output from this supply are dangerous and can be
lethal. Extreme caution must be exercised when working with this
equipment.
Do not handle or attempt to handle the high voltage load or any exposed
high voltage connections. Do not attempt to make or remove any
connections to the supply until the load has been properly discharged or
grounded.
Always make sure the load return is connected to the ground stud located
below the HV connector (or is otherwise similarly grounded).
ƒ
The input power supply ground connection must remain intact for a minimum of 2
minutes after disabling the HV output to allow sufficient time to fully discharge the
supply.
ƒ
Even with the remote or local current or voltage program signals set to minimum, the HV
output can regulate up to 1% of the rated output when the supply is enabled.
ƒ
At no time should the internal control panel be removed. There are no user adjustable
elements or user interfaces below this cover. Additionally, the supply warranty can
become void due to unauthorized removal of the control panel.
4.0
Connections:
This equipment is supplied with three connectors and a ground stud. These connectors are as
follows:
5.0
ƒ
HV Out: The high voltage output cable is connected to this connector. It has
1 1/8"- 18 threads and leads to a 0.55" nominal inside diameter tube that is terminated to
the supply high voltage output via a banana jack located 14.6" nominally from the end of
this connector.
ƒ
Input Power: The input power is connected to the (Thomas and Betts, P/N MS206 insert
in PB306 base, or similar) power connector via a customer wired mating connector
(Thomas and Betts, P/N FS106 insert in THF06 hood, or similar). See Figure 2, section 9
for pin identification.
ƒ
Interface: The interface connector (Thomas and Betts, P/N FS116A insert in PB316A bas,
or similar) provides all the necessary connections for complete local and/or remote
control of output programming, output monitoring, interlock and HV enable functions.
See Figure 3, section 9 for specific pin identification.
ƒ
Ground Stud: Before power is applied to this supply, this ground stud must be properly
connected to a good earth ground. Additionally, the load return must be connected to this
ground stud.
Panel Controls and Indicators
Reference Figure 4, section 9 for control panel layout.
ƒ
Input Voltage Selector: Located on the interior control panel. Position slide switch to
display the proper supplied input power (either 115V or 230V). Ensure the slide selector
is in the correct position prior to applying power to the supply. FAILURE TO DO SO
CAN RESULT IN DAMAGE TO THE POWER SUPPLY.
ƒ
Input Power Switch: Located on the interior control panel. When proper AC voltage is
supplied at the input power connector, this switch provides AC power to the supply when
switched to the “I” position. NOTE: For remote operations, this switch must be in the “I”
position for the supply to function.
ƒ
HV Control: Located on the interior control panel. With power applied to the supply, this
switch is used to enable or disable the HV output when operating in local control mode.
This switch will not enable the HV output if the interlock pins are open.
ƒ
Current and Voltage Control Potentiometers: Located on the interior control panel. The
current control (left side) and the voltage control (right side) are used in the local control
operation mode to adjust the program current or program voltage settings. These 10-turn
potentiometers include a lever lock on the dial to secure the potentiometer in the selected
position.
ƒ
Current/Voltage Selector Switch: Located on the interior control panel. This switch will
select between current or voltage parameters being displayed on the panel meter. It can be
used in local or remote control operating modes.
ƒ
Program/Monitor Selector Switch: Located on the interior control panel. This switch is
used in conjunction with the Current/Voltage selector switch to select the parameter being
displayed on the panel meter. It can be used in local and remote control operating modes.
ƒ
Panel Meter: Located on the interior control panel. With the selector switches in the
desired positions, this meter will display the selected parameter for current or voltage.
Current is displayed in mA units while voltage is displayed in kV units. All measurements
displayed are positive values regardless of the supply polarity. The panel meter functions
can be used in local and remote control operating modes.
ƒ
HV ON Indicators: One is located on the interior control panel and one is located on the
side of the enclosure. When the HV output is enabled (whether voltage is at the output or
not) these red colored indicators will be illuminated.
ƒ
PS Fault Indicators: One is located on the interior control panel and one is located on the
side of the enclosure. When the power supply enters a fault condition, these yellow
colored indicators will be illuminated. The HV output will also be disabled.
CAUTION! Even if the HV output becomes disabled, the load
may still be charged to dangerous levels. Do not attempt to make
or remove any connection or to handle or move the load or exposed
high voltage connections until the load has been properly discharged.
ƒ
AC ON Indicator: Located on side of enclosure. This is a white colored lighted fuse
indicator that remains lit while power is supplied to the power supply and the input power
switch is in the “I” position. The fuse is a 5A, time delay type (1/4" x 1 1/4", MDL-5 or
equivalent).
6.0 Interface Functions
NOTE: All DC signal voltages noted below are with respect to the power supply common.
Remote Interface:
ƒ
Current Program In: Provide a positive 0 - 10VDC signal to linearly adjust the output
current programming from 0 to 100% of rated.
ƒ
Voltage Program In: : Provide a positive 0 - 10VDC signal to linearly adjust the output
voltage programming from 0 to 100% of rated.
ƒ
Current Monitor: A positive 0 – 10VDC signal that is proportional to the output current is
available at this terminal. The measuring instrumentation must have a high input
impedance (> 10MΩ).
ƒ
Voltage Monitor: A positive 0 – 10VDC signal that is proportional to the output voltage is
available at this terminal. The measuring instrumentation must have a high input
impedance (> 10MΩ).
ƒ
HV Enable: By providing a positive nominal 10-12VDC (<2mA) signal to this terminal,
the power supply HV output will be enabled (if the external interlock terminals are
shorted together). When the HV has been enabled, the red HV ON indicators will be
illuminated. Transition voltage thresholds are:
>10VDC = HV enabled;
< 2.3VDC = HV disabled
ƒ
PS Fault/PS Fault Return: (reference Figure 2, in section 9) These are a set of normally
closed dry contacts indicating a no fault condition. A PS fault occurs when 8 arc events
are detected in a 20 second period. When a PS fault occurs, the unit is latched in an HV
disabled mode. To clear the latched fault condition, the input power must be cycled by
first switching the power off for at least 10 seconds followed by switching the power back
on. Contact conditions between these terminals for fault are:
Closed = no fault
Open = fault
ƒ
Shield Return: In remote control operations, a good quality shielded cable must be used
for the interface functions. A cable shield connected to this terminal will be tied to the
power supply chassis.
7.0
ƒ
Power Supply Common: This terminal is the instrumentation/measurement return
reference. It must not be used as a current return for the load or as the main earth
ground.
ƒ
External Interlock/External Interlock Return: These terminals are provided for contact
closure control of the safety interlock. The power supply will be fully functional when
these terminals are shorted together. When these terminals are not shorted together, no
output or control operations are possible. CAUTION: If the HV has been locally or
remotely set to an enabled state, the power supply will immediately enter an HV enabled
condition when the external interlock terminals are shorted together.
ƒ
+12V Reference: This terminal provides a positive 12VDC, 12mA maximum source that
may be used with contact closure control to provide the HV Enable signal.
Mounting
Four through-hole mounting feet are provided on the bottom of the enclosure for securing the
supply as required. During shipping, these feet are positioned completely under the enclosure.
To position them for mounting, the box-head cap screws securing each mounting foot may be
loosened and the foot rotated in 90 degree increments to the desired mounting position.
Properly re-secure the foot with the cap screw.

Operation
WARNING: Voltages used in and the output from this supply are
dangerous and can be lethal. Extreme caution must be exercised when
working with this equipment. Before operating this equipment, the safety
precautions of Section 3 must be reviewed and applied.
Remote Control Operation
ƒ
Prior to providing any remote control signals to the supply, ensure the input power switch
located on the interior control panel is set to the “I” position. Provide output
programming signals, HV Enable and external interlock signals as described in section 9
for remote control operation of the supply. (Reference Figures 5 through 11 in section
9).
Local Control Operation
The HVP is supplied with a special mating connector for use during local control operations.
This connector provides the following:
1) Programming Outputs shorted to Programming Inputs
- I Program Out shorted to I program In
- V Program Out shorted to V Program In
2) Interlock Out is shorted to Interlock In
3) HV Enable is shorted to Local Enable
Before installing the local control connector, verify the power supply is properly grounded
through the ground stud and the HV load is returned to the same ground stud. Check to make
sure the power switch is set to the “O” position and the HV control switch is set to
“Disabled”.
ƒ
Connect the local control connector to the interface connector. The external interlock is
internally connected in this connector.
ƒ
Set both the current and voltage control potentiometers fully counterclockwise to the
minimum output setting.
ƒ
Set the Input Power switch the “I” position.
ƒ
Set the HV control switch to the enabled position.
ƒ
Program the output current or output voltage by moving the program/Monitor selector
switch to “Program” and setting the Current/Voltage selector switch to the desired
parameter. Adjust the output current or output voltage control potentiometers while
viewing the programmed settings on the panel meter (output current is displayed as
positive mA values and output voltage is displayed as positive kV values).
NOTE: When operating in the voltage regulation mode, the output current program
level must be higher than the expected output operating current to prevent the
power supply from unintentionally crossing over into current regulation mode.
If operating in current regulation mode, the output voltage program level must be
set higher than the expected operating voltage to prevent the supply from
unintentionally crossing over into voltage regulation mode.
ƒ
Monitor the output current and output voltage on the panel meter by moving the Program/
Monitor selector switch to “Monitor” and selecting the desired parameter with the
Current/Voltage selector switch (output current is displayed as positive mA values and
output voltage is displayed as positive kV values).
