Specifications
Power
The impulse 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. Air is drawn in from the front into each of the
modules except for the PSU's that use a large heat sink.
The DSP module has two 80mm fans mounted on its front panel, the Control Processor Module
and each of the four Router modules have two 40mm fans one mounted in the front panel and one
in the bottom of the module blowing upwards.
This fan arrangement pulls air through the module frame which then exits through vents across the
top and rear of the core.
All fans are speed monitored and System Status error message are generated for any failures. To
ensure air can flow through the card frame freely, the air vents at the rear of the core should be left
clear and unobstructed. No clearance is required above or below the core for cooling.

Cooling
The Impulse Core Unit is 5U and is cooled under control with fan assistance.
The PSU’s are cooled by heatsink only, however the Control Processor, Router and DSP modules
are cooled by a variety of fans.
Fan speed is monitored and system status warnings are generated if fans fail.
The front & rear panels of the unit should be unobstructed to allow airflow.
No clearance is required above or below the unit.
