1.1 Description of the X2364
he X2364 high voltage power supply represents an
advanced approach to X-ray generator power
requirements. This power supply provides all of the
power, control, and support functions required for
practically all X-ray applications. The X2364 provides
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.
These advancements are possible by Spellman’s long
history in X-ray power systems. This power supply
utilizes extremely advanced resonant conversion
techniques, along with sophisticated digital technology.
The X2364 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 remotely via
the built-in RS232 Interface.
The power supply operates from 187Vac to 264Vac
mains.
1.2 X2364 Specifications
Specifications are customized to meet specific customer
needs. See Appendix B for the detailed Specification
Control Drawing.
1.3 Standard Features
The X2364 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.
INTERNAL FAULT PROTECTION:
The X2364
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:
A Spellman Delrin HV receptacle is
designed to mate with an Anden P5 Series high voltage
cable. The modified Alden P5 cable assembly, Spellman
P/N 303217-002, is 42 inches long.
1.3.1 Remote Control via RS232
Interface
RS232 INTERFACE:
An internal RS232 Interface
provides all the remote functions to operate the X3145.
Please see Chapter 8 for complete details.
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.
