Abstract: A device for the regulation of devices which can be regulated with a 0-10 Vdc and/or PWM command is herein disclosed, the device having at least one power supply input, at least one regulation input adapted to receive external regulation signals, a potentiometer comprising a selector element, the potentiometer being configured to provide a manual voltage regulation, and at least one command output configured to output a command signal towards the devices to be regulated. The device further comprises a switching element configured to cause a switching of said device between a first regulation mode, in which the command signal is generated by said device and is manually adjustable through the selector element of said potentiometer, and a second regulation mode, which allows a regulation of the devices to be regulated via the command signal from the command output based on an external device connectable to the regulation input. A system comprising the above device is also disclosed.

Abstract: A system is disclosed for managing a set of electrical/electronic devices for driving fans of a heat exchanger of a refrigeration plant, having a basic control unit adapted to act as interface between a remote control unit/Master unit and a plurality of electrical/electronic devices to be controlled. The basic control unit has a data input to receive inputs from the remote control unit/Master unit and a plurality of data outputs connectable with respective electrical/electronic devices of the electrical/electronic devices. The basic control unit is configured to address the electrical/electronic devices using management signals to program the operating parameters of the electrical/electronic devices, and to directly manage the operation. The management signals include addressing, programming and management commands previously programmed in the memory unit based on specific applications and communication protocols.
