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 EY Series of 1200 watt high voltage supplies feature flexible embedded controls withlow ripple and noise. They are air insulated,
fast response units, with tight regulation andextremely low arc discharge currents.
Please refer to Technology > Applications pageon our web site for typical applications.
The EY Series are fully compliant with theFollowing European Directives:
EN61000-3-2, Line Harmonics
EN61010/ IEC61010, Safety
EN61000-6-4, Conducted and RadiatedEmissions
EN61000-6-2:2005, Conducted and RadiatedImmunity
2011/65/EU, Restriction of the use ofhazardous 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 provide
remote control program and monitor.

Low Ripple. Typically, ripple is less thanConstant 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.

0.02% RMS of rated voltage at full load.

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

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.

regulation mode, better than 0.1%
from short circuit to rated voltage
at any load condition.

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 load
discharges. If the rate of consecutive
arcs 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:

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