Features:
Arc Quench. The HV output is inhibited
for a short period after each load arc to help
extinguish the arc.
Arc Count. Internal circuitry constantly
senses and integrates arcs that occur overa given time. In the event a system or load
arcing problem develops and exceeds factory-set parameters, the power supply will
cycle off in an attempt to clear the fault
and then automatically restart after a preset “off dwell time”.

Pulse-Width Modulation. Off-the-line
The FJ Series of 120 watt high voltage supplies feature flexible embedded controls with low
ripple and noise. They are air insulated, fast
response units, with tight regulation andextremely low arc discharge currents.
Please refer to Technology > Applications page on
our web site for typical applications.
The FJ Series with 22 option, are fully compliant
with the Following European Directives:EN61000-3-2, Line Harmonics
EN61010/ IEC61010, Safety
EN61000-6-4, Conducted and Radiated Emissions
EN61000-6-2:2005, Conducted and RadiatedImmunity.
2011/65/EU, Restriction of the use of Hazardous
Substances (RoHS)

CE (Meets all applicable directives), UKCA
(Meets all applicable legislation)pulse-width modulation provides highefficiency and a reduced parts countfor improved reliability.

Embedded Microcontroller control.
Front panel digital encoders provide highresolution local adjustment of voltage andcurrent program. Integral RS-232, USB andoptional ethernet communications provideremote control program and monitor.

Low Ripple. Typically, ripple is less than
0.02% RMS of rated voltage at full load.

Constant Voltage/Constant Current
Operation. Automatic crossover fromconstant-voltage to constant-current regulation provides protection against overloads, arcs, and short circuits.

Redundant Thermal Overload
Protection. Thermostats and fan RPM
sensing shut down the power supply due
to over temperature or reduced
fan speeds.

Tight Regulation. Voltage regulation isbetter than 0.005% for allowable line andload variations. Current regulation is better than 0.1% from short circuit
to rated voltage.
Constant Current/Current Trip. A rear
panel switch allows selection of either current mode.
Slow Start. Adjustable ramp time from 0 30 seconds. Output ramps from 0 V to programmed voltage level.
Warranty. All power supplies are warranted
for three years. A formal warranty statement is available.

Air Insulated. The FJ Series features “air”
as the primary dielectric medium. No oilor encapsulation is used to impede serviceability or increase weight.

XP PowerSpecifications(Specifications apply from 5% to 100%
rated voltage. Operation is guaranteed
down to zero voltage with a slightdegradation of performance.)
Input: User selectable via rear panel
switch, 102 - 132 V RMS or 198 to 264
VRMS single-phase, 48-63 Hz, 300 VA
maximum at full load. C14 connector
per IEC 60320 with mating line cords
SHIPPED SET FOR 198 to 264.
Efficiency: Typically greater than 85%
at full load.
Output: Continuous, stable adjustment, from 0 to rated voltage or current by panel mounted optical rotary
encoder or by external +10V signals.
Voltage accuracy is 0.5% of setting +0.2% of rated. Optical rotary encoder
resolution: 0.025% with "FineAdjustment" mode selected. 0.25%
with "Coarse Adjustment" mode(default). Repeatability is < 0.1% ofrated.
Static Voltage Regulation: Better than
±0.005% for specified line variations
and 0.005% + 0.5 mV/mA for no load
to full load variations.
Dynamic Voltage Regulation: Forload transients from 10% to 99%
and 99% to 10%, typical deviation isless than 2% of rated output voltage
with recovery to within 1% in 500 us
and recovery to within 0.1% in 1 ms.
Ripple: Better than 0.02% of rated
voltage + 0.5 V RMS at full load.
Current Regulation: When in current
regulation mode, better than 0.1%
from short circuit to rated voltage
at any load condition.
Voltage Monitor: 0 to +10 V
equivalent to 0 to rated voltage.
Accuracy: 0.5% of reading + 0.2%of rated. Impedance is 10 KW.
Current Monitor: 0 to +10 V equivalent
to 0 to rated current. Accuracy: 1% ofreading + 0.1% of rated. Impedance is10 KW.

Stability: 0.01% per hour after 1/2 hourwarm-up, 0.05% per 8 hours.
Voltage Rise/Decay Time Constant:
The voltage rise time constant is 50 ms
typical for all models using either HVenable or remote programming control.
The voltage decay time constant is 50
ms with an 80% resistive load for 10 kV
to 60 kV models and 50 ms with a 10%
resistive load for 1 kV to 8 kV models.
Temperature Coefficient: 0.01% /°C.
Ambient Temperature: -20 to +40° C,operating; -40 to +85° C, storage.
Polarity: Available with either positive,
negative or reversible polarity withrespect to chassis ground.
Protection: Automatic current
regulation protects against all
overloads, including arcs and shortcircuits. Thermal switches and RPM
sensing fans protect against thermal
overload. Fuses, surge-limiting
resistors, and low energy components
provide ultimate protection.
Arc Quench: An arc quench featureprovides sensing of each load arc andquickly inhibits the HV output for
approximately 20 ms after eacharc. Standard on 8 - 60 kV models;
optional on 1- 6 kV models.
Arc Count: Internal circuitry senses thenumber of arcs caused by external loaddischarges. If the rate of consecutivearcs exceeds approximately one arc persecond for five arcs, the supply willturn off for approximately 5 seconds toallow clearance of the fault. After thisperiod the supply will automatically
return to the programmed kV value
with the rise time constant indicated.
If the load fault still exists, the above
cycle will repeat. Standard on 8 - 60 kVmodels; optional on 1- 6 kV models.
External Interlock: Open = off,
closed = on. Normally latching except
for blank front panel version where it
is non-latching.
Remote HV Enable/Disable:
0 - 1.5 V = OFF, 2.5 - 15 V = ON.
RS232/USB/Ethernet Programming andMonitor Accuracy:

programs. 0.1% of full scale forboth the voltage and the current
monitors
