The DC power for the Gold Drum HV (High Voltage) is delivered from a separated rectifying unit
(supplied by the user). Elmo recommends using the Tambourine 100 rectifier specifically
designed for use with Elmo drives which offers a range of versatile options.
The following sections contain topology recommendations for implementing three-phase and a
single-phase supply chains.
The power stage of the Gold Drum HV (High Voltage) is fully isolated from the other sections of
the Gold Drum HV (High Voltage), such as the control-stage and the heat sink. This isolation
allows the user to connect the common of the control section to the PE, a connection which
significantly contributes to proper functionality, safety and EMI immunity, leading to better
performance of the Gold Drum HV (High Voltage).
In addition, this isolation simplifies the requirements of the DC power supply that is used to
power the DC bus of the Gold Drum HV (High Voltage), by allowing it to operate with a non-
isolated DC power source (a direct-to-mains connection) which eliminates the need for a bulky
and expensive isolation transformer.
