Ideal negative supply rail
Simscape / Electrical / Sources
The Negative Supply Rail block represents an ideal negative supply rail. Use this block instead of the Simscape™DC Voltage Source block to define the output voltage relative to the SimscapeElectrical Reference block that must appear in each model.
Do not attach more than one Negative Supply Rail block to any connected line.
-— Negative voltage
Electrical conserving port associated to the negative supply rail negative voltage.
Constant voltage— Constant output voltage
The voltage at the output port relative to the Electrical Reference block ground port.
