3.3.2 Inrush current limitation
The LINUS5-C 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 20 A rms*.
*Maximum rms value of inrush current over one half-cycle of the mains voltage according to IEC/EN 55032:2016-02
(Electromagnetic compatibility of multimedia equipment - Emission requirements: German version EN 55032:2012/
AC:2013).
NOTE: Even under normal conditions the mains current can reach levels up to 32 A/64 A (230 V/115 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 Ω to avoid flicker according to EN 61000-3-11 “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” (IEC 77A/929/CDV:2016). If in any doubt,
consult your local power provider. Never attempt to measure this impedance level with your Ωmeter. This may damage
your meter and expose you to the risk of electric shock.
3.3.3 Mains power consumption and current draw
Due to the huge outout power of LINUS5-C 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 consumption 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 115 V mains operation, the current values can be multiplied by 2.
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.
