Programming & Controls All Types
Voltage regulation (VDC) Line: less than 0.05% ±1V change in output voltage for a 10% change in line voltage
Load: less than 0.05% ±1V change in output voltage for a 0 to100% change in load current
Voltage ripple Voltage mode: less than 0.1% of rated output voltage +2V, peak to peak
Current mode: less than 0.5% of rated output voltage peak to peak
Current regulation Line: less than 0.5% of rated output current for a 10% change in line voltage
Load: less than 0.5% of rated output current for a 0 to 100% change in output voltage

Temperature coefficient Less than 200ppm/°C
Operating temperature 0°C to+ 40°C (32°F to 140°F)
Storage temperature -20°C to +70°C (-4°F to 158°F)
Humidity 80% maximum relative humidity up to 31°C, reducing linearly to 50% at 40°C. Non-condensing. (ref. BS EN61010-1)
Safety The Series OL1K meets the requirements of the Low Voltage Directive, 2006/95/EEC, by complying with BS EN61010-1:2001 when installed as a component part of compliant equipment.  Units are CE marked accordingly.
Safety class Equipment class 1
Usage Indoor use only
Protection The units are fully protected against over-temperature and over-current, peak arc current is resistively limited
Arc count and extinguish 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 to 25 arcs in any 5 second period.
Installation category II (BS EN61010-1)
Pollution degree 2 (BS EN61010-1)
RoHS The OL1K 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.
Status indication Uses the alphanumeric display to show the reason for any trip condition.
Altitude Sea level to 2000 metres (6500 feet)
Protection The units are fully protected against flashover and continuous short circuit (no trip)
EMC The Series OL1K is intended for installation as a component of a system is 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
EN61000-4-5 surges - levels ±2kV line to earth, ±1kV line to line
EN61000-4-8 magnetic fields - levels 30A/m at 50/60Hz
EN61000-4-11 voltage dips, interruptions
The unit will not trip and recovers to normal operation after a disturbance as defined in SEMI F47-0706.
The EMC performance of the power supply can only be fully assessed when installed within, and as a part of, the final system.
Cooling Fan assisted, air is drawn in via side panel vents and exits at the rear of the unit.  Minimum air flow required is 3m/s.  Ambient air around the unit must not exceed 40°C
Recovery time Less than 500ms to within 0.1% of previous operating level following a short circuit or arc.  Maximum overshoot 2% of rated output voltage
Drift Less than 0.02% per hour after 1 hour warm up
Specification range Specifications apply above 5% of rated output voltage.  The output can be controlled down to less than 0.25% of rated output voltage
