Power Consumption
The dCS 904 has a linear power supply, and so power consumption changes as
the mains voltage changes. The internal regulation is comparatively efficient for
a linear supply, so these changes are kept to a minimum. Power consumption is
independent of mains voltage selector switch setting.
Power Consumption with Mains Voltage (measured as AC power into mains
socket):
Nominal mains 25 W
Mains -10% 22 W
Mains +10% 27 W
The actual intended supply voltage is shown on the rear panel. 50 Hz or 60 Hz
operation is not important – the unit can use either. In general, users will not
need to change the mains input configuration. If you do need this to be done,
please see the section "Having Your Options Changed”, page 68 in this
manual and contact your distributor or dCS.
