INTRODUCTION
1.1 Description of the XLG/XLF Series
he XLG/XLF series of high voltage power supplies represent an advanced approach to X-ray generator
T
power requirements. These power supplies provide all of the power, control, and support functions required for practically all X-ray applications. The XLG/XLF 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. These series of power supplies utilize extremely advanced resonant conversion techniques, along with sophisticated digital technology.
The XLF series is specifically designed for X-ray tube application where the high voltage is a negative polarity, and the filament circuits are referenced to the cathode high voltage potential, (floating filament). The XLG series is specifically designed for X-ray tube applications where the high voltage is a positive polarity, and the filament circuits are referenced to cathode ground potential, (grounded filament).
The X-ray tube voltage and tube emission current are all continuously adjustable via front panel and/or remote controls.
The power supplies operate from a variety of line voltages and are convection cooled for 1 – 300W models and fan cooled for 800 to 1200W models requiring no water cooling. Custom designed units for single use or OEM applications are available.

1.3 Standard Features
The XLG/XLF 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 6 seconds. The filament current is slowly increased until the desired mA level is achieved. This time is typically 5 seconds for full mA output. These ramp conditions are started at the initial HV ON control signal.
ARC DETECT / ARC QUENCH / ARC COUNT: These features allow the user to tailor the power supply to meet specific needs in dynamic load applications. If an arc occurs, the output is inhibited for approximately one second, then the output is ramped up to the preset level with the Slow-start circuitry. See Chapter 3 for operating details and information for user customization for these features.
REMOTE HIGH VOLTAGE CONTROL: Allows remote control of the HIGH VOLTAGE ON and HIGH VOLTAGE OFF functions. Signals are also provided for remote indication of HV ON or HV OFF status.
EXTERNAL INHIBIT: A circuit that will inhibit the high voltage output is provided of the 25 pin mini-D connector on the rear of the chassis. A logic low, ground, will inhibit the high voltage output and a logic high, open, will restore the high voltage output to the preset level. NOTE: The External Inhibit circuit should NOT be used for protection against injury or for safety interlock. See External Interlock for this type of safety control
EXTERNAL INTERLOCK: Interlock connections are provided on the terminal block on the rear of the chassis 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 High Voltage to shut off. This circuit should be used for safety interlock circuits.
INTERNAL FAULT PROTECTION: The XLG/XLF series continually monitors internal circuits critical to the proper operation of the power supply. In the event that one of these circuits does not function correctly, the fault detection circuit latches the appropriate fault on the front panel display and turns off the outputs and reverts the unit to the POWER DOWN mode.
INDICATOR LAMPS: HIGH VOLTAGE OFF and HIGH VOLTAGE ON indicators.
OUTPUT CABLE: XLG models are provided with a ten foot 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 rear of the chassis. internal EMI filter and fuse provide protection against line voltage surges and power supply faults.
1.3.1 Remote Operating Features
REMOTE PROGRAMMING: Allows remote adjustment of the output voltage and current via an external voltage source. The output power is also remotely controllable when the CPC or APT option is ordered.
REMOTE MONITOR: Allows remote monitoring of the tube voltage and tube emission current. NOTE: Output power remote monitor is included with the CPC and APT options.
1.3.2 System Status and Fault Diagnostic Display
“Dead Front” type indicators are provided to give the user complete indication of system operation and fault conditions. If a fault occurs the power supply will revert to the POWER DOWN mode. This is indicated by both the HV ON and HV OFF lamps turning off. To reset, depress the HV OFF switch.
VOLTAGE (CONTROL): Indicates the output voltage regulator circuit is maintaining voltage regulation.
CURRENT (CONTROL): Indicates the output current regulator circuit is maintaining current regulation.
POWER (CONTROL): Indicates the output power regulator circuit is limiting tube power (optional).
HV INHIBIT: Indicates the high voltage supply is being inhibited by either the EXTERNAL INHIBIT or internal protection circuitry.
INTLK CLSD: Indicates the EXTERNAL INTERLOCK connections are in the closed position. This also indicates closure of internal power supply interlocks.
INTLK OPEN: Indicates the EXTERNAL INTERLOCK connections are in the open position. This also indicates opening of internal power supply interlocks.
XLG/XLF MANUAL 2 118020-001 REV E
Page 10
OVERVOLT: Indicates the overvoltage protection circuitry has caused the power supply to turn off. Overvoltage protection is internally set to 110% of rated output voltage.
OVERCURR: Indicates the output current has exceeded the programmed current trip level when the AOL (Adjustable Overload Trip) or the OL (overload Trip) options are installed.
The options available are listed kin 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.
OVERPWR: Indicates the output power has exceeded the internally set level or the remote programmed level if the optional circuitry is installed.
ARC: Indicates that an arc has occurred within the previous one second or that the ARC COUNT/TRIP has shutdown the power supply.
RGLT ERR: Indicates a failure in the voltage, current or power regulation circuitry. This fault usually occurs when there is a lack of output power to maintain regulation.
FILAMENT STANDBY/LIMIT (rear panel):
Indicates the filament is in a standby or limit mode. Also, when illuminated, this indicates the emission current regulator is not regulating.

Operating Instructions
3.1 Operation
WARNING
THIS EQUIPMENT GENERATES
DANGEROUS VOLTAGES THAT MAY BE
FATAL.
PROPER GROUNDING OF ALL HIGH
VOLTAGE EQUIPMENT IS ESSENTIAL.
WARNING:
Before connecting the power supply to the
AC line, follow this step-by-step procedure. Do not connect the power supply to the AC
line until Step H is reached.
Failure to follow these procedures may void
the warranty.
A) Insure that the Circuit Breaker is in the OFF position (0).
B) 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 XLG/XLF units operate on 115VAC (or 220V if 220 V option is ordered), single phase unless ordered with a different input voltage.
C) 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, 3.2 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.
The units are provided with a three conductor line cord. D) Attach the output cable to the load. E) Plug the high-voltage output cable into the rear
of the supply and hand tighten the knurled collar.
XLG/XLF MANUAL 6 118020-001 REV E
F) 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.
G) For initial turn-on, rotate the KILOVOLT control fully counter-clockwise to the zero voltage position.
H) The input power cable may now be connected to the AC power line.
I) Switch the front panel circuit breaker to the ON position (1). (If the supply is to be turned off for an extended period of time the line cord should be disconnected). The unit is now in the HIGH VOLTAGE OFF mode. The HIGH VOLTAGE OFF light should be lit.
J) Depress and hold the HIGH VOLTAGE OFF switch. The front panel meters will now read the preset value of the KILOVOLT control dial and the MILLAMPERES control dial. To preset the desired level of the current and voltage during operation, hold the HIGH VOLTAGE OFF switch and rotate the appropriate control dial while noting its corresponding meter reading. Release the HIGH VOLTAGE OFF switch.
NOTE: No actual output is being produced at this stage. K) Depress the HIGH VOLTAGE ON switch. The
light inside the switch should light up and the output will slow start to the preset level output voltage and/or output current.
Note: The XLG/XLF series is equipped with a slow start circuit that ramps the output up to its maximum setting in approximately 6 seconds after the HIGH VOLTAGE ON switch is depressed.
L) To terminate the generation of output power, depress the HIGH VOLTAGE OFF switch. In the HIGH VOLTAGE OFF mode the power supply’s fault and interface circuits are still active.
M) To turn off the power supply, turn the circuit breaker to the off position (0).
NOTE: If a power supply fault, or system monitoring fault occurs, the power supply will revert to the POWER DOWN mode. In this mode the output power will be turned off. The HV OFF lamp will be off. To reset, depress the HV OFF Switch.

control (front panel control), jumpers are installed on the connector JB1 in the rear of the chassis between JB1-10 and JB1-11 for voltage control and between JB1-8 and JB1-9 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 JB1-1 signal ground. By adjusting the voltage source from 0 volts (zero output) to 10 volts (full rated output) the desired output can be selected. See Figure 3.3A 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 3.3B for wiring diagram.
ALWAYS OPERATE THE UNIT WITH THE COVER
ON.
A fan maintains safe operating temperature in the XLF power supplies by drawing air over the circuit components. The cover must be on in order to direct the air flow over the areas that need cooling. In operation, the unit must be places so that the air intake and the fan exhaust are clear of any obstructions that might impede the flow of air. The XLG units do not use forced air cooling. Simply maintain ambient temperature specifications.
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. For status signals and control signals such as HIGH VOLTAGE ON, HIGH VOLTAGE OFF, EXTERNAL INHIBIT, etc. Opto-isolation 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 on the rear terminal block JB1-1.
REMOTE PROGRAMMING: Allows remote adjustment of the output voltage and current via an external voltage source. (Output power is also remotely controllable with the CPC and APT options). In local
REMOTE MONITOR: Test points are made available on the rear of the chassis for monitoring the voltage and current output. (Output power monitor is included with the CPC and APT option). The test points are always positive regardless of the output polarity, where zero 0 to 10 volts equals 0-100% of output ±0.5%. Test points have an output impedance of 5k ohms. See Figure 3.4 for test point designation.
REMOTE CONTROL: Remote control of the POWER ON, HIGH VOLTAGE ON and HIGH VOLTAGE OFF can be accomplished via the rear panel interface. The POWER ON control is an on-off toggle contact. HIGH VOLTAGE OFF and HIGH VOLTAGE ON are controlled by momentary normally closed normally open contacts, respectively. See Figure 3.5 for recommended interface.
EXTERNAL INHIBIT: Allows the user to inhibit the power supply output without switching HIGH VOLTAGE OFF control. This circuit can be used to generate fast slewing output waveforms or control high voltage generation as in Laser and Capacitor discharge applications. The maximum inhibit rate should not exceed 5Hz. Consult factory for higher repetition rates or high pulse load applications. See Figure 3.6 for the recommended interface circuit.
WARNING
It is extremely dangerous to use this
Inhibit circuit to inhibit high voltage
generation for the purpose of servicing
or approaching any area of load
considered unsafe during normal use.
XLG/XLF MANUAL 7 118020-001 REV E
Page 15
EXTERNAL INTERLOCK: Interlock connections are provided on the terminal on the rear of the chassis for connection to a safety switch. The unit will not operate unless the interlock circuit is closed. If the interlock is not being used, the jumper installed on the terminals before shipping must be in place. If the jumper is missing, or there is an open between the interlock terminals the unit’s high voltage inverter will be disabled. During high voltage operation, opening the interlock circuit will cause the unit to revert to the HIGH VOLTAGE OFF mode. Subsequent closing of the interlock circuit will NOT return the unit to HIGH VOLTAGE ON mode, this must be accomplished by depressing the HIGH VOLTAGE ON switch. See Figure
3.7 for the recommended interface circuit. ARC DETECT / ARC QUENCH ARC COUNT: The
ARC DETECT circuit senses dynamic arcing or discharge conditions present at the output load. If an arc occurs, the output is inhibited for one second. After the one-second period, the output is ramped up to the previous set level. This ramp is based on the standard six-second slow start feature. The ARC DETECT ramp circuit may be disabled by removing CR32 on the
Control/Power PWB. Caution should be observed if this feature is disabled. Discharge rates of greater than 1 Hz may cause excessive power dissipation in the power supply’s output limiting resistors.
The ARC COUNT feature will allow the user to program the ARC fault parameters. The ARC indicator on the front panel will illuminate for approximately one second after each arc has occurred. The power supply can be programmed to trip to the POWER DOWN mode if an arc occurs. The standard feature is programmed to trip the power supply if 8 arcs occur within a twenty second period.
REMOTE HIGH VOLTAGE ON & REMOTE HIGH VOLTAGE OFF: Signals are provided for remote
monitoring of the HIGH VOLTAGE ON/OFF status. See Figure 3.8 for recommended interface.
REMOTE MODE INDICATORS: Signals are provided for remote indication of the control mode status, voltage control, current control and power control. See Figure 3.9 for the recommended interface.

PRINCIPLES OF OPERATION
he XLG/XLF series of high voltage power supplies utilizes sophisticated power conversion technology.
T
A 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 XLG/XLF power supply. For details on a specific circuit, consult Spellman’s Engineering Department.
See Table 4.1 for a list of the main assemblies found in a typical XLG/XLF power supply.
* Due to the many variations within the XLG/XLF series, drawing numbers may differ from unit to unit.
The XLG/XLF power supply is basically an AC to DC converter. Within the power supply, conversions of AC to DC, then high frequency AC, then to high voltage DC take place. By reviewing further the sub-assemblies, a basic understanding of the process can be gained.
4.1 Chassis
The XLG/XLF is a compact, high efficiency, high voltage power supply. The power supply can supply up to 600 watts of DC power. (Output power capability may be higher or lower depending upon model ordered). Output voltages of up to 130kV 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.
4.2 Line Rectification and Filtering
Basic single phase rectification provides the DC voltage for the high frequency inverter. The line input voltage can vary from 90 up to 242 volts within the XLG/XLF series.
In general, the following variations can be ordered: 100Vac ±10%, 50/60Hz, single phase. 115Vac ±10%, 50/60Hz, single phase. 200Vac ±10%, 50/60Hz, single phase. 220Vac ±10%, 50/60Hz, single phase. Other input voltages can be accommodated. If the user is
unsure which input voltage option is supplied, check the serial tag on the rear of the power supply or consult Spellman’s Sales Department
Circuit protection is provided by CB1 (SYSTEM BLOCK DIAGRAM CHASSIS XLG/XLF SCHEMATIC). CB1 is a fast acting magnetic trip type circuit breaker. The line input is connected directly to the line side of CB1. The load side of CB1 is connected to the CONTROL/POWER PWB. The load side of CB1 is also connected to T1. T1 is a step-down type line transformer. T1 provides voltage for housekeeping and control circuit power.
WARNING
LINE VOLTAGE IS PRESENT WHENEVER THE
POWER SUPPLY IS CONNECTED TO EXTERNAL
LINE VOLTAGES. BE SURE TO DISCONNECT
THE LINE CORD BEFORE OPENING THE UNIT.
ALLOW 5 MINUTES FOR INTERNAL
CAPACITANCE TO DISCHARGE BEFORE
REMOVING ANY COVER.
When CB1 is ON, voltage is applied to CR10. CR10 is an isolated diode rectifier bridge that contains the rectifier diodes used for line voltage rectification. The output of CR10 is connected to a capacitor filter (C7 through C10). Capacitors are initially charged through NTC type or resistive inrush limiters.
Approximately 1 second after CB1 is turned on, a relay is energized to short the NTC or resistor limiters. This relay is K1. This DC voltage is supplied to the high frequency inverter.
The DC rails are connected to the high frequency rail capacitors. These capacitors are high frequency, low loss type. Capacitors C11, C12, C54, and C55 provide the energy storage for the high frequency inverter.

Table 4.1 List of Main Assemblies
4.3 Inverter
The inverter is a series resonant, series/parallel loaded topology. A proprietary control scheme is used for regulating the power generated from the inverter. Q2, Q3, Q4, and Q5 are high speed Mosfets. These devices provide high frequency switching to control the resonant current flow. The typical resonant operating period is approximately 10uSeconds. The gate control for the switching devices is provided by T2 on the CONTROL/POWER PWB. The CONTROL/POWER PWB also provides circuitry for sensing shoot thru and over current conditions in the inverter. U10 and its associated circuitry automatically shutdown the inverter. U18 provides for the gates high current pulse requirements. T2 provides line voltage isolation
4.4 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 1kV to 4.5kV depending upon output voltage ratings.
4.5 High Voltage Assembly
The High Voltage Assembly will vary depending upon the model ordered. The circuitry typically consists of a full wave, full bridge. The higher voltage ranges utilize various parallel, series arrangements of a full wave voltage doubler.
Output filtering is typically provided by an R-C type filter. Voltage feedback for regulation and monitoring is provided by a high bandwidth resistive/capacitiv e divider.
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.
4.6 Control/Power PWB
The majority of control circuits for power supply controls are located on the CONTROL/POWER PWB.
+15VDC, -15VDC, and +10VDC is generated on the CONTROL/POWER PWB. High Voltage On/Off control is accomplished by K3, and its associated circuitry. Interlock control is provided by K4.
Voltage feedback from the high voltage divider is sent to U6. Gain adjust is provided on the HV PWB. The KV feedback signal is sent to the front panel DVM and to the REAR PANEL TERMINAL BLOCK for remote monitoring. K2 provides switching between feedback and program signal for the front panel DVM’s. This allows the user to preset the desired output before energizing high voltage.
Program voltages are typically ramped up to set level by the slow start circuits of U7.
Arc sense circuits U14 and U23 provide sensing, quench and indication of arc conditions. Consult operation manual for a detailed description of the arc sense control.
Current feedback from the high voltage rectifier is sent to sense resistors located on the High Voltage Assembly. Calibrated feedback is then sent to U4.
An overvoltage protection circuit provides protection in the unlikely event of a main control loop failure. U9 provides gain adjustments for the overvoltage protection (OVP) control.
XLG/XLF MANUAL 17 118020-001 REV E
Page 25
U12 and U13 circuits provide visual indication of the control mode, which is in operation. These signals are sent to the FRONT PANEL ASSEMBLY for front panel status indication.
The resonant control circuitry consists of a voltage to pulse width converter. U17 generates all frequency and pulse width control signals. U16 provides specific control functions for the resonant control.
Power supply inhibit circuits are provided by U22 and K3. System Fault Control and Indication is provided by U19m U20, and U21 and associated circuitry. Diagnostic signals are latched and then sent to the FRONT PANEL ASSEMBLY for status indication.
4.7 Front Panel Assembly
Front Panel control meters, and status indications are connected to the FRONT PANEL PWB. The FRONT
PANEL PWB interfaces directly to the CONTROL/POWER PWB.
4.8 Filament Supply PWB
The power for the X-ray tube is provided by the filament inverter. The filament inverter is a high frequency, series resonant inverter. The inverter provides regulated current to the primary of the filament transformer. The filament isolation transformer is then connected to the output connector.
4.9 Options
Due to the many variations of models and options provided in the XLG/XLF 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 XLG/XLF series.

OPTIONS
He options available for this power supply are
described in this section. Interface diagrams are
T
shown where required. Options are specified by including the option code in the model number as described in Section 1.5.
5.1 Adjustable Overload Trip AOL
The overload trip protection feature rapidly shuts down the high voltage output when the load current exceeds the limit set by the current control dial on the front panel. A fast acting circuit inhibits the generation of high voltage and reverts the unit to POWER DOWN mode, illuminating the OVER CURRENT indicator. When adjustable overload trip is provided, it replaces the standard current regulation feature.
5.2 220V AC Single Phase Input 220
XLG/XLF power supplies with the 220 V AC input option will operate from an input voltage of 220VAC rms ±10%, 50-60hZ, single phase.
5.3 No Slow Start NSS
The no slow start option causes the output voltage of the power supply to rise (within 50 msec) to the rated voltage upon depressing the HIGH VOLTAGE ON Switch.
5.4 Non-Standard Slow Start SS(x)
5.6 Adjustable Power Trip APT
The power control options allow monitoring and control of the power supply output power. The APT option allows the user to remotely adjust the power limit for the power supply. If the power limit is exceeded, the unit will shut down with an OVERPOWER fault. See Figure
5.2 or remote interface.
5.7 Arc Trip Option AT
When this option is ordered, the ARC Count circuit is set so the unit trips to Standby after 1 count.
One of the applications for this option is for sensing material breakdown under an applied high voltage.
5.8 Instant On IO
When the Instant On option is ordered, the High Voltage is enabled as soon as line voltage is applied when the circuit breaker is in the ON position.
To enable Instant ON, keep the jumper between JB1-14 and JB1-15 attached. Connect an additional jumper from JB1-15 to JB1-16 as shown in Figure 5.1
CAUTION
The Power Supply will generate programmed High
Voltage whenever the circuit breaker is in the ON
position, and line voltage is applied.
The non-standard slow start option allows the gradual rise time of the output voltage to be different from the standard of six seconds. To order the option, place the time desired in seconds after the suffix letter; i.e. SS(10) denotes a 10 second rise time.
5.5 Extra Length Output Cable LL(ft)
Standard output cable is 10’ of shielded high voltage cable. Other lengths may be specified in multiples of 10 feet.
