3.3.2 Inrush current limitiation
The
LINUS10
has a special processor dedicated to limit the mains inrush
current.
This limiter will take action anytime:
– when connecting the amplifier to the mains through the mains cable
– when switching the amplifier on through an external mains breaker
– the mains voltage was lost for at least 4 half-cycles or more (e.g. a short
voltage drop)
This limiter will confine the mains current to a value smaller than 17 A *.
rms
*: maximum rms value of inrush current over one half-cycle of the mains voltage according to DIN EN
55103-1
.
NOTE:
Even under normal conditions the mains current can reach levels up
to 32 A / 64 A (230 V / 120 V) and even higher for very short periods of time.
This could cause lamps to flicker if connected to the same mains as the am-
plifier. The impedance of the AC circuit should be less than 0,157
Ù
to avoid
flicker according to EN61000-3-11 “Electromagnetic compatibility – Part 3-
11: Limits – Limitation of voltage changes, voltage fluctuations, and flicker
in the public low-voltage supply systems – Equipment with rated current
≤
75 A and subject to conditional connection”. If in any doubt, consult your
local power provider. Never attempt to measure this impedance level with
your ohmmeter. This may damage your meter and expose you to the risk
of electric shock!
3.3.3 Mains power consuption and current draw
Due to the huge output power of the
LINUS10
, the mains current draw can
get very high when demanding large output powers. Please refer to follow-
ing table for an overview of mains currents and power cunsuption under
different operating conditions.

Mains current draw and power consumption @ 230 V, 50 Hz
Measured with pink noise with crest factor of 12 dB to represent typical music signal.
For 120 V mains operation, the current values can be multiplied by 2.
*: duration limited by FuseProtect limiter
Please note that the values given here are typical values only, measured
on a standard 230 V / 50 Hz outlet. The actual mains current draw can vary
depending on the music signal and the mains characteristics (especially
the mains impedance) of any specific installation.
