The DC power for the Gold Drum is delivered from a separated rectifying unit (supplied by the user).
Elmo recommends using one of Elmo’s Tambourine rectifiers specifically designed for use with Elmo
servo drives which offers a range of versatile options.
9.6. Main Power
The power stage of the Gold Drum is fully isolated from the other sections of the Gold Drum, such
as the control-stage and the heat sink. This allows powering of the Gold Drum in two ways:
1.
Direct to mains power supply connection. The Gold Drum is powered by a power source
that is not isolated from the mains.
2.
Isolated from the mains Power supply connection. The Power supply of the Gold Drum is
isolated from the mains by an isolation transformer, or the power source is a battery
isolated from the mains.
The Gold Drum series is offered with six different operating voltage ranges. This allows optimum
servo performance and superior efficiency at any voltage. When rectifying an AC voltage source, the
AC voltage level must be limited to the "voltage supply" rating shown in Table 1, section 4.2.

Power Supply Connections
This section relates to the configuration of the power supply and drive, which is the DC power
source for the Gold Drum.
Connection:
1.
For best EMI emission and immunity, it is highly recommended to use twisted and shielded
cable for the DC power supply cable. The gauge is determined by the actual current
consumption of the motor.
2.
The Motor’s cable must not be twisted! Twisted wires create capacitance between the wires
and thus increase the EMI.
In very long Motor twisted cables ( >50m) this Capacitance might activate the short circuit
protection.
3.
Connect the Power wires and cables as recommended in the connection diagrams.
