DESCRIPTION
The HiTek Power Series OL400W range of single output high voltage
power supplies meets the exacting requirements found in electron
and ion beam systems. The OL400W is also suitable for use in X-ray
systems, ion and chemical vapour deposition and general laboratory
use.
Designed using the latest power switching IGBTs to ensure efficient
and reliable operation over the full operating range the Series OL400W
will give excellent performance in the most severe of electrical
environments. The Series OL400W utilises air as the primary insulation
medium for voltages up to 60kV; achieving a high packing density for
high voltage supplies giving 65W/litre, 1W/inch
3
. The 1U construction
(2U for 80kV units) allows operation at full power when close mounted
in a standard equipment rack, giving significant savings in rack space
in large systems. Featuring HiTek Power’s proprietary Arc Count and
Extinguish (ACE) system for managing systems where load arcing is
possible, the Series OL400W protects both itself and the load from
damage that may be caused by excessive arcing whilst allowing
normal operation to continue.

Portability:
Non-portable.
EMC:
The Series OL400W is intended for installation as a component of a
system.
Designed to meet:
EN55022 class B for conducted and radiated emissions
EN61000-4-2 ESD – levels ±4kV contact, ±8kV air discharge
EN61000-4-4 Fast transients on mains input – levels ±2kV

The unit will not trip and recovers to normal operation after a
disturbance as defined in SEMI F47.
The EMC performance of the power supply can only be fully assessed
when installed within, and as part of, the final system.
RoHS:
The Series OL400W meets the requirements of EU Directive 2011/65/EU
on the Restriction of use of certain Hazardous Substances in electrical
and electronic equipment (RoHS).
Metering:
Provided as part of an alphanumeric display. Voltages are displayed with
a resolution better than 0.5% of rated output. Current is displayed with
a resolution of better than 1.5% of rated output. Voltage and current set
values can be displayed by pressing the relevant control potentiometer.
Status Indication:
Uses the alphanumeric display to show the reason for any trip
condition.
Cooling:
Fan assisted with fan fail detection. Air inlets at the rear of the unit,
exhaust on the side panels and top cover. Minimum air flow required is
3m/s at the input to the fan.
For slide mounting a 15mm gap shall be provided above the unit for air
exhaust if the side air vents are blocked.
For shelf mounting no gap is required above or below the unit provided
the side air vents are clear by at least 15mm.

Arc Count and Extinguish (ACE):
Each time the ACE system detects an arc it blanks the supply off for a
brief period to extinguish the arc. The unit is then allowed to recover.
If more arcs occur they are counted to determine the arc rate; if this
exceeds a safe level the power supply is shut down. The parameters
are factory set.
Operating Temperature:
0ºC to +40ºC (32°F to 140°F).
Storage Temperature:
-20ºC to +70ºC (-4°F to 158°F).
Humidity:
80% maximum relative humidity up to 31ºC, reducing linearly to 50% at
40ºC. Non-condensing. (ref. BS EN61010-1)
Altitude:
Sea level to 2000 metres (6500 feet).
Safety:
Meets the requirements of the Low Voltage Directive, 2006/95/EC, by
complying with BS EN61010-1 when installed as a component part of
compliant equipment. It is CE marked accordingly.
Safety Class:
Equipment Class 1.
