6.3. Main and Auxiliary Power
6.3.1. Description
The Gold Duo receives power from main and auxiliary supplies and delivers power to the motor.
Note: There are multiple voltage ratings of the Gold Duo (12 V to 195 V), so you must use the
correct power supply according to the maximum operating voltage of the Gold Duo. Refer to
Chapter 4: Technical Information.
This section describes the Main and Auxiliary Power for power ratings 200V and 100V, and provides
details for the optional Backup (Auxiliary) Supply.
• The Gold Duo Power rating is 12 to 195 VDC
• There are Two power ratings for Gold Duo; 100V and 200V:
 For power rating 200V
Two power isolated DC power sources are required, main power 12 - 195V and Auxiliary
Power 12-95V for the logic.
 For power rating of 100V
Single DC Power Supply - Power to the Gold Duo is provided by a 12–95 VDC single isolated
DC power source (not included with the Gold Duo). A “smart” control-supply algorithm
enables the Gold Duo to operate with only one power supply with no need for an auxiliary
power supply for the logic.
Optional Backup (Auxiliary) Supply
If backup functionality is required in case of power loss, e.g., to keep the original position, a 12–95
VDC external isolated supply should be connected (via the Gold Duo’s VL+ terminal). This is more
flexible than the requirement for 24 VDC supply.
If backup is not needed, a single power supply is used for both the power and logic circuits.
There are two voltage ratings of the Gold Duo, therefore the correct power supply must be used,
according to the maximum operating voltage of the Gold Duo. Refer to section 4.2 Technical Data.
