3.5.1. Connecting Main Power
Power to the Solo Whistle is provided by a 12 to 195 VDC source. A smart control-supply
algorithm enables the Solo Whistle to operate with the power supply only in up to 100 V
models, with no need for an auxiliary 24 volt supply.
200 V models always require two separate power supplies.
If backup functionality is required (for storing control parameters in case of power-outs) an
additional backup supply can be connected by implementing "diode coupling" to the VL+.
Note: The source of the 12 to 195 VDC Main Power Supply must be isolated.
