DESCRIPTION
The Series OL20K is a range of high reliability products designed to
meet the rigorous requirements of ion and electron beam systems.
These high performance switch mode systems are based on a power
converter using zero-volt switching. A full bridge of the latest
generation of Insulated Gate Bipolar Transistors (IGBTs) in a fully
regulated closed-loop system capable of continuously supplying up
to 20kW of output power whilst maintaining flexible control down to
a few hundred Watts. These highly reliable rugged systems comprise
two units, a rack mounting power converter through which remote
controls are facilitated, and a separate HV unit employing a modular
disc construction. Numerous features are incorporated to ensure
system integrity is maintained during adverse operating conditions.
Such features include continuous primary current monitoring with
fast pulse truncation and soft recovery, extensive thermal monitoring
and automatic shutdown on key components, passive output current
limiting for instantaneous surge control and independent output
overvoltage sensing. Optionally HiTek Power’s Arc Count and
Extinguish (ACE) system can be installed for active arc management.
Input Voltage:
208VAC ±10% (187VAC to 229VAC) 47-63Hz 3 phase via three M8 studs,
and earth, via M10 stud at 87A rms per phase.
OR
400VAC ±10% (360VAC to 440VAC) 47-63Hz 3 phase via three M6 studs,
and earth, via M8 stud 45A rms per phase.
Polarity:
Positive or negative to order.
Minimum Voltage:
5% of rated output voltage. The unit may be turned down below this but
the specifications are not guaranteed below this level.
Line Regulation:
Less than 0.1% change in output voltage for a 10% change in mains
voltage.
Load Regulation:
Less than 0.1% of rated output voltage for a full load change.
Ripple:
Less than 0.1% peak to peak of rated output voltage.
Transient Response:
The output will recover to within ±1% of set value in less than 100ms
from the removal of a short circuit.
Temperature Coefficient:
200ppm/oC (0.02%/oC).
SPECIFICATION
Output Power:
20kW maximum at full rated output voltage and current.
Output Voltage:
Units available with maximum output voltages from 60kV to 200kV.
Output Current:
Up to 250mA for 60kV and 80mA for 200kV.

Test conditions as defined in table A.1.
Altitude:
Sea level to 2000 metres (6500 feet).
Installation Category:
II (BS EN61010-1)
Pollution Degree:
2 (BS EN61010-1)
Usage:
Indoor use only.
Control:
The power supply is operated by remote control via the 25-way D-type
connector situated on the rear panel of the converter. Full control and
monitoring functions are available by this method. Application of 0 to
10V to the voltage and current control lines programmes the unit for 0 to
100% of rated output. Similarly 0 to 10V signals provide monitors of the
output voltage and current levels. HV ON/OFF is obtained by shorting
two teminals and status lines are provided by open collector outputs.
Protection:
The units are fully protected against over voltage, over current, over
temperature, load arcing and output short circuits. The ACE system
can be installed to give added arc management functionality.
Safety:
The OL20K high voltage power supplies meet the requirements of the
Low Voltage Directive, LVD, 73/23/EEC by complying with BS EN61010-
1:2001 when installed as a component part of other equipment. They
are CE marked accordingly.
RoHS:
The OL20K is currently built to non-RoHS standard. This unit can,
however, be configured to meet the requirements of RoHS where
significant customer demand requires it, although please note that this
will have an impact on delivery timescales.
