DC 12 V +10 %, -15 %, stabilized (SELV). With power
supply units from other suppliers, ensure that the output
current limiting is < 5 A.
A connected SIMATRIX can take over the power supply for the control
unit with cable lengths < 70 m. The voltage at the input of the control
unit must not fall below the previously defined tolerances as a result of
transmission losses.
