1)
Power consumption is, to a great extent, independent of the operating voltage. It does,
however, depend on the signalling tone and the sound pressure level. The given value specifies
the highest power consumption of the device.
2)
The power factor of the alternating current version depends on the operating voltage. The
following formula determines the operating voltage dependent operating current I

of the device.
