The Positive Supply Rail block represents an ideal positive supply rail. Use this block instead of the Simscape DC Voltage Source block to define the output voltage relative to the Simscape Electrical Reference block that must appear in each model.

The voltage at the output port relative to the Electrical Reference block ground port. The value must be greater than zero. The default value is 1 V.
The block has the following ports:
Simscape DC Voltage Source, Negative Supply Rail
![]() | PNP Bipolar Transistor | Proximity Sensor | ![]() |
