Specifications
Power
The processing core is fitted with two AC mains input power supply modules. The core will be
fully functional on one PSU, however both should be fitted and fed where possible from separate
sources to provide redundancy against both PSU failure and external power loss.
The operating AC supply voltage is 100V–240V +/-10%.
The inrush current is actively limited to 13A peak at 230V (6.5A at 115V) per power supply
module. This much reduces the chance of a nuisance trip or fuse blow from a hot start after a
momentary brownout or blackout of the AC power. The quiescent current can be specified for any
configuration of core.
Active PFC (Power Factor Correction) is employed in the power supplies and the PF (Power
Factor) is greater than 0.9 under all operating conditions.
Heat Output & Efficiency
The Heat output from the core is nominally 0.93 times the RMS VA (Volts x Amperes).
These figures can be provided for any core configuration.
Cooling
The core is cooled by fan assisted convection. Fan speed is monitored and System Status
warnings generated if any fan slows or stops.
The 8U Artemis Beam/Shine core is fitted with 6 x 120mm low power, low speed and low noise
fans, mounted inside the top of the core. Air is drawn in from the cable-tray and up through the
bottom of the cardframe. Air is vented out of the top of the rear of the core.
The 4U Artemis Light core is fitted with 9 x 40mm low power, low speed and low noise fans,
mounted at the top of the rear of the core outputting air. Air is drawn in through the front panels of
the card modules fitted in the core.
The design of both core types allows them to be fitted in bays with no clearance above or below.
At least 50mm (2') clearance must be maintained at the top of the rear of the cores to allow the
fans / vents to dissipate air. The 8U core cable tray or 4U front panel inlets should not be blocked
and allowed sufficient clearance to maintain cooling.
The core may be mounted in an open bay providing the ambient air temperature is within limits
(see below). The core may also be housed in an air conditioned bay providing the air pressure is
negative. Consult factory for positive air pressure systems.
