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.

Size and Weight

The dCS 904 dimensions correspond to a standard 2U 19" rack mount case. Four heavy duty feet, fitted to the base, extend the overall height to slightly greater than 2U.
