d3c does not have a built-in power supply. Instead it uses a plug-in type external power
supply (AC adapter). One reason for this feature is electrical safety. Keeping danger voltages
(mains) out of the d3c increases the electrical safety. Another reason for the external power
supply is the fact that line voltages and plug types vary considerably from country to country.
Using a plug-in external supply the d3c can be used anywhere with a locally purchased
power supply, thus keeping the retail price down.

(labelled 9V DC Out) is used to pass on
the supply voltage to the d3m unit(s) provided that one or two d3m are used in combination
with the d3c. Consequently only one power supply is necessary for the complete system
(d3c+d3m or d3c+2xd3m).

enclosed. Otherwise they have to be ordered later.
In Europe a VDE approved power supply (9V/800mA) is included with the d3c. This supply is
sufficient for up to one d3c and two d3m (see below). In other countries a power supply with
suitable mains voltage and mains connector has to be purchased separately by the user
provided that the dealer resp. representative does not enclose the power suppy. The power
supply must be able to deliver 7-12 VDC stabilized or unstabilized voltage, as well as a
minimum current of 250mA (if only the d3c is used). The correct polarity of the DC voltage
connector is: outside ring = GND, inside lead = +7...12V. An external power supply of high
quality and safety should be used. If one or two d3m have to be supplied with the same
power supply additional 250 mA are required for each d3m (i.e. 500mA for d3c + d3m,
750mA for d3c + 2x d3m).
The d3c is switched on by plugging the AC adapter into a wall outlet and connecting it to the
appropriate jack of the d3c. There is no separate on/off switch. If the polarity of the power
supply is incorrect, the d3c will not function. However, there is no danger of damage to the
circuitry since it is protected by a diode.
