POWER/ENVIRONMENTAL SPECIFICATION
CONTROL SURFACE
Power
The console has two IEC AC power inlets feeding two sets of internal power distribution for each
set of 4 sections. Although the console will operate with one inlet supply per 4 sections, we
recommend both inlets are powered. This will ensure continued operation should a PSU or AC
source fail.
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 4 x internal PSU.
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 total peak inrush current and quiescent current can
be specified for any size of console. There is a peak operating current when the motorised faders
move. The worst case is if all the faders move end to end where the peak power will be 4 Watts per
fader for <120ms.
Active PFC (Power Factor Correction) is employed in the power supplies and the PF (Power
Factor)
is typically greater than 0.88 dependant on console size.
The power measurements for 4 sections, 3 sections, 2 sections & 1 section are shown below.
Heat Output & Efficiency
The Heat output from the console is typically 0.9 times the RMS VA (Volts x Amperes).
These figures can be provided for any size of console.
The PSU efficiency under all operating conditions is typically greater than 85%, dependant on
console size.
Cooling
The control surface is cooled by natural air convection. The air intake is on the underside of the
console and the outtake is along the top rear of the console. At least 50mm (2') clearance must
be maintained for these vents.
