1.0 General
Switch mode power supply for cathodic corrosion protection applications
The REOTRON SMP range of DC Power units are primary-switched power supplies with galvanic isolat-
ed output voltage. The units can be used voltage controller or current controller, or as a combined unit to
control both voltage and current. The units can be operated locally from a control panel or (switchable)
from external control signals.
Set point inputs for current and voltage are provided for external control. The set point signals may be a
control voltage 0…+10 V, DC or a control current 4…20 mA. In addition it is possible to switch ON and
OFF the output electronically (without galvanic separation) by the means of an inhibiting input. This inhib-
iting input can be operated with a potential-free contact or a control v24 V, DC.
To monitor the protective current the effective actual values of current and voltage are generated by one
each 4…20 mA control signal and are available on terminals.
With an interface option can be communicated via Fieldbus (Profibus-DP, DeviceNet, CAN-Bus or Ether-
CAT) connection.
The units are built into compact aluminium enclosures for the assembly into a switching cabinet.
