2.2.2. Supply Input
• Single DC Power Supply - Power to the Gold Guitar is provided by a 14 to 195 VDC single
isolated DC power source (not included with the Gold Guitar). A “smart” control-supply
algorithm enables the Gold Guitar to operate with only one power supply with no need for
an auxiliary power supply for the logic.
• Optional Backup Supply - If backup functionality is required in case of power loss, e.g., to
keep the original position, a 14 to 195 VDC external isolated supply should be connected
(via the Gold Guitar’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 multiple voltage ratings of the Gold Guitar (14 V to 195 V), so you must use
the correct power supply according to the maximum operating voltage of the Gold
Guitar. Refer to the section 3.1 Technical Data.
