uX MANUAL 118152-001 Rev A
Page 2
The uX Series is the result of Spellman’s exceptional
high voltage packaging and surface mount fabrication
techniques coupled with proprietary encapsulation
technology producing this ultra-compact X-Ray generator
module. The uX powers grounded cathode X-Ray tubes
from a variety of well-known manufacturers, featuring a
0 to 50kV/65kV high voltage output @ 2mA limited to 50,
65 or 75 Watts. The uX uses closed loop filament control
circuitry providing highly regulated beam current. The low
noise dc filament supply operates between 0.3 and 3.5
amps. Offering tight regulation, high stability and low
ripple, the uX provides users local and remote analog
control to set beam voltage, emission current and filament
current limit. USB, RS-232 and Ethernet interface is standard.

Grid Bias Option (GB):
Plug-n-Play compatibility for Oxford’s Apogee X-Ray Tube
Spellman’s Grid Bias Option for the uX Series is specifically
designed for popular commercially available grid bias X-Ray
tubes. The Grid Bias voltage is developed via the use of separate integrated high frequency switching circuit, providing maximum flexibility and control. The Grid Bias output is a voltage
regulated, current compliant topology ideally suited for Wehnelt
electrode applications. Arc and short circuit protection of the
Grid Bias output prevents any damage due to transient events
or installation errors.
Tracking Mode Operation
Functioning in tracking mode the voltage monitor
(0-10Vdc = 0 to 50kV) of the main high voltage output
is internally connected to the Grid Bias programming input
(0-10Vdc = 0 to -300Vdc of Grid Bias). Connected in this
manner the Grid Bias output will track in a linearly
proportional fashion the setting of the main kV output.
A multiturn potentiometer limits the maximum magnitude
of Grid Bias output applied to the X-Ray tube, providing
unparalleled flexibility.
The output of the Grid Bias option is provided via an
auxiliary two position Phoenix Contact terminal block, the
mating connecter is provided.

INTRODUCTION
1.1 Description of the uX Series
he uX series of high voltage power supplies represent
an advanced approach to X-ray generator power
T
requirements. These power supplies provide all the
power, control, and support functions required for
practically all X-ray applications. The uX series provide
high voltage, high current outputs with very low ripple.
Extremely stable voltage and current outputs result in
significant performance improvements over previously
available technology. Low output ripple provides higher
intensity levels, with no increase in tube loading.
All these advancements are possible only by Spellman’s
long history in X-ray power systems. This series of
power supplies utilize extremely advanced resonant
conversion techniques, along with sophisticated digital
technology.
The uX series is specifically designed for X-ray tube
application where the high voltage is a positive polarity,
and the filament circuits are referenced to the cathode
ground potential, (grounded filament).
The X-ray tube voltage and tube emission current are all
continuously adjustable.
The power supplies operate from +24Vdc and are
convection cooled for 0 to 75W models. Custom
designed units for single use or OEM applications are
available.
uX MANUAL 1 118151-001 REV A

1.2 Standard Features
y
r
r
The uX series incorporates several standard features
designed to optimize user satisfaction and safety.
KV AND MA/FILAMENT CURRENT RAMP
CIRCUITS: This feature provides for a gradual rise for
kV, mA and filament current. This feature is designed to
limit voltage shock and filament shock to the X-ray tube.
The kV ramp rate is approximately 4 seconds. The
filament current is slowly increased until the desired mA
level is achieved. This time is typically 4 seconds for full
mA output. These ramp conditions are started at the initial
INTERLOCK CLOSED control signal. Prior to closing
the Interlock the filament operates at a user determined
preheat current level. Preheat levels are selected for the
desired X-ray tube to minimize mA overshoot.
INDICATOR LEDS: HIGH VOLTAGE ON and
POWER ON indicators.
OUTPUT CABLE: Standard units are provided with a 1
meter shielded high voltage output cable. The cables are
designed with a plug arrangement so that they can be
easily removed from the mating receptacle located on the
front of the chassis. For non-standard units, see Spec.
Control drawing.
LOCAL AND REMOTE PROGRAMMING:
Potentiometers accessible through the top cover are
provided for controlling tube voltage, tube emission
current, tube filament limit set point and tube filament
preheat set point.
If fail-safe interlocking of the X-ray On is not required the
lamp can be replaced with a 270 Ohm, 1 W resistor.
Provisions are provided for isolating the interlock relay
coil from the internal +24V, allowing the user to connect
the coil to an external +12V source. This eliminates the
need for either the lamp or the 270-Ohm resistor allowing
pin 4 to be grounded for HIGH VOLTAGE ON control.
See Figure 3.4 for alternate Interlock Configurations.
1.4 Options
CODE DISCRIPTION
• XCC XRM Compatible HV Cable (50kV only)
• 5VPM 0 to 5 Volt Programming and Monitor
Scaling
• GB Grid Bias Option.
• K5302 Mammoflex HV cable for uX
• K2001 Mammoflex HV cable for uX w/XCC
option
Table 1.1 uX Options
The options available are listed in Table 1.1. See Section
5 for more information on these options along with
operating and set-up instructions. With few exceptions,
these options and modifications can be retrofitted to your
power supply at the factory in a short time. For price and
retrofit arrangements, contact Spellman’s Sales
Department.
Tube voltage and tube emission current can also be
controlled remotely via the Analog Interface connector
(J4).
1.2.1 Remote Operating Features
REMOTE MONITOR: Allows remote monitoring of
the tube voltage, tube emission current, tube filament
current, tube filament limit set point and tube filament
preheat set point via the Analog Interface connector.
EXTERNAL INTERLOCK: Interlock connections are
provided on the Analog Interface connector on the front
of the chassis for connection to a safety switch. The unit
will not operate unless the interlock circuit is closed. The
recommended configuration is to close the interlock
circuit through a 12V lamp rated for 0.5W to 0.8W and a
safety switch. This configuration provides fail safe
interlocking. During high voltage operation, opening the
safety switch or failure of the 12V lamp will cause the
High Voltage to shut OFF. This option should be used for
safety interlock circuits.
1.4 Interpreting the Model
Number:

A) Check the input voltage rating on the nameplate
of the supply and make certain that this is the rating of the
available power source. Spellman uX units operate on
24Vdc unless ordered with a different input voltage.
B) PROPER GROUNDING TECHNIQUE: The
chassis of high voltage power supplies must be grounded,
preferably to a water system ground using copper pipe or
other earth ground using the connection terminal at the
rear of the unit. See Figure 3.1, for a typical operating
setup.
The return line from the load should be connected to the
terminal on the rear of the power supply. Using a
separate external ground at the load is not recommended.
C) Attach the output cable to the load.
D) Plug the high voltage output cable into the front
of the supply and hand tighten the knurled collar.
E) Options Note: See section 5 for hook up and
operating instructions for the options on your unit.
Custom models may also require set up changes.
F) For initial turn-on, set the programming voltage
to the zero voltage position.
G) The input power cable may now be connected
and power applied. The POWER ON LED should light
up. No high voltage will be generated at this time.
H) Close the INTERLOCK. The HIGH VOLTAGE
ON LED should light up and the output will slow start to
the preset level output voltage and/or output current.
NOTE: The uX series is equipped with a slow start
circuit that ramps the output up to its maximum setting in
approximately 4 seconds after the INTERLOCK is closed.
I) To terminate the generation of output power,
open the INTERLOCK. In the HIGH VOLTAGE OFF
mode the power supply’s fault and interface circuits are
still active and the filament operates at the Preheat level.
J) To turn off the power supply, disconnect the
power.

3.2 Standard Features
A note on remote interface circuitry and remote signal
grounding. Whenever possible, electrical isolation should
be provided when interfacing with any high voltage
power supply. For power control signals such as
EXTERNAL INTERLOCK, HIGH VOLTAGE OFF and
HIGH VOLTAGE ON isolated relay contacts should be
used. If possible, analog programming and monitoring
signals should be isolated via analog isolation amplifiers.
Spellman application engineers are available to assist in
interface circuitry design. All interface cables should be
properly shielded. All power supply signals should be
referenced to the power supplies signal ground.
LOCAL AND REMOTE PROGRAMMING: Allows
the operator to select local or remote adjustment of the
output voltage and current. Adjustments are made using
the screwdriver adjustable potentiometers accessible
through the top cover of the power supply or via an
external voltage source provided by the operator. In local
control jumpers are installed on the 15 pin interface
connector between pin 7 and pin 8 for voltage control and
between pin 10 and pin 11 for current control.
For remote programming, the jumpers are removed and a
positive voltage source, from 0 to 10 volts, is applied to
the appropriate terminals. Programming signals should be
referenced to signal ground. By adjusting the voltage
source from 0 volts (zero output) to 10 volts (full rated
output) the desired output can be selected. 0 to 5 volts
equals 0-100% of output on units with 5VPM option. See
Figure 3.4 for wiring diagram and specifications.
An alternate method of controlling the output remotely is
by using external resistance such as a potentiometer or a
resistor network. For remote control the jumpers are
removed and the desired resistor configuration is
installed. See Figure 3.4 for wiring diagram.
REMOTE MONITOR: Test points are made available
on the 15 pin D connector for monitoring the voltage,
current and filament outputs and for reading the filament
current limit and preheat set points. The test points are
always positive regardless of the output polarity, where 0
to 10 volts equals 0-100% of output on standard units. 0
to 5 volts equals 0-100% of output on units with 5VPM
option. Test points have an output impedance of 1K
ohms. See Figure 3.3 for test point designation.
EXTERNAL INTERLOCK: Interlock connections are
provided on the 15 pin D connector for connection to a
safety switch. The unit will not operate unless the
interlock circuit is closed. During high voltage operation,
opening the interlock circuit will cause the unit to revert
to the HIGH VOLTAGE OFF mode. See Figure 3.3 for
the recommended interface circuit.
uX MANUAL 7 118151-001 REV A
Page 20
FILAMENT LIMIT: The maximum current that the
filament power supply can operate is user adjustable from
1.0A to 3.5A. The Limit adjustment is made when the
power supply is in the high voltage OFF mode (Interlock
Open) via the screwdriver adjustable potentiometer
labeled “FIL I LIM ADJ” that is accessible through the top
cover.
A test point is provided on pin 9 on the 15 pin D connector
for monitoring the Filament Limit set point. The test point
scaling is 1VDC = 1amp. See Figure 3.3 for the
recommended interface circuit.
the +24VDC input power is applied to the unit and the
Interlock is Open (High Voltage OFF). The Preheat Level
is adjustable from between .8A to 2.5A.
Selecting the correct preheat current level can greatly
reduce or eliminate the overshoot that typically occurs on
the output emission current when operating into a “cold
filament”.
The Preheat adjustment is made when the power supply is
in the high voltage OFF mode (Interlock Open) via the
screwdriver adjustable potentiometer labeled “PH ADJ”
that is accessible through the top cover.
Due to the wide variety of X-ray tubes available, uX
power supplies are shipped with the Filament Limit set for
minimum. The operator must set filament limit at the time
of installation in accordance with the X-ray tube
manufacturers recommendations.

Principles of Operation
he uX series of modular X-ray generators utilizes
sophisticated power conversion technology. A
T
variety of analog, digital and power conversion
techniques are used throughout. The intention of the
Principles of Operation is to introduce the basic function
blocks that comprise the uX power supply. For details on
a specific circuit, consult Spellman’s Engineering
Department.
The uX power supply is basically a DC-to-DC converter.
Within the power supply, conversions of DC to high
frequency AC, then to high voltage DC takes place. By
reviewing further the sub-assemblies, a basic
understanding of the process can be gained.
WARNING
To reduce the risk of fire, replace fuse with same type and
rating.
WARNING
Um die Brandgefahr zu verringern, muss die Sicherung
durch eine neue gleichen Typs ersetzt werden.
4.1 Chassis
The uX is a compact, high efficiency, X-ray generator.
The power supply can supply up to 75 watts of DC power.
(Output power capability may be higher or lower
depending upon model ordered). Output voltages of up to
65kV can be generated.
WARNING
The energy levels used and generated by the
power supply can be lethal! Do not attempt to
operate the power supply unless the user has a
sufficient knowledge of the dangers and hazards
of working with high voltage. Do not attempt to
approach or touch any internal or external
circuits or components that are connected or
have been connected to the power supply. Be
certain to discharge any stored energy that may
be present before and after the power supply is
used. Consult IEEE recommended practices for
safety in high voltage testing #510-1983.
WARNUNG
Die verwendete und erzeugte Engergie des
Hochspannungsnetzteiles kann tötlich sein! Betreiben Sie
das Hochspannungsnetzeil nur wenn Sie ausreichendes
Kenntnis über mögliche Gefahren beim Ungang mit der
Hochspannung haben. Versuchen Sie nicht interne
Schaltkreise oder elektrische Bauelemente, die an das
Hochspannungsnetzteil angeschlossen sind, zu berühren.
Vergewissern Sie sich, daß alle Restladungen, die vor
oder nacj dem Betreib des Hochspannungsnetzteils
vrhanden sind, entladen werden. Weitere Informationen
finden Sie der IEEE-Vorschrift Nr. 510-1983.
4.2 Inverter
The inverter is a series resonant, parallel loaded topology.
A PWM scheme is used for regulating the power
generated from the inverter. Q1 is a high speed
MOSFET. This device provides high frequency
switching to control the resonant current flow. The
typical resonant operating period is approximately 15μ
seconds.
uX MANUAL 12 118151-001 REV A
Page 25
4.3 High Voltage Transformer
The output of the High Frequency Resonant Inverter is
connected to the primary of the High Voltage
Transformer. The High Voltage Transformer is a step-up
type. Typically secondary voltages are in the range of
5kV depending upon output voltage ratings.
4.4 High Voltage Assembly
The High Voltage Assembly will vary depending upon
the model ordered. The circuitry typically consists of
series arrangements of a half wave voltage multiplier.
The higher voltage ranges utilize various series
arrangements of a voltage doubler.
Output filtering is typically provided by an R-C type
filter. A high bandwidth resistive/capacitive divider
provides voltage feedback for regulation and monitoring.
Current feedback for regulation and monitoring is
provided by a sense resistor connected at the low voltage
end of the High Voltage Rectifier/Multiplier Circuit.
4.5 Control PWB
The majority of control circuits for power supply controls
are located on the CONTROL/POWER PWB.
+15VDC, -15VDC, and +10VDC are generated on the
CONTROL/POWER PWB. High Voltage On/Off control
is accomplished by K2, and its associated circuitry.
Interlock control is provided by K2.
Voltage feedback from a high voltage divider, located on
the High Voltage Assembly, is sent to U16. Gain
adjustment is provided by R98. The KV feedback signal
is sent to the 15 pin D connector for remote monitoring.
Program voltages are typically ramped up to set level by
the slow start circuits of U16.
Current feedback from the high voltage rectifier is sent to
sense resistors located on the High Voltage Assembly.
Feedback is then sent to U15.
The resonant control circuitry consists of a voltage to
pulse width converter. U17 generates all pulse width
control signals.
4.6 Filament Supply
The filament inverter provides the power for the X-ray
tube filament. The filament inverter is a high frequency
inverter. The inverter provides regulated current to the
primary of the filament transformer. The filament
isolation transformer secondary is then connected to the
output connector.
4.7 Options
Due to the many variations of models and options
provided in the uX series, details of actual circuits used
may differ slightly from above descriptions. Consult
Spellman’s Engineering Department for questions
regarding the principles of operations for the uX series.
