The relay type SCF is intended for synchronizing of generator units and paralleling to the network.
Several functions, which are necessary to carry out the paralleling, are accomodated in a single relay. The design is based on a microprocessor to assure a high degree of adaptivity and ease of use.The relay SCF features the following principal characteristics:

• possibility to control both frequency and voltage of the interested machine;
• setting of the operative parameters by means of the membrane front keyboard;
• direct read-out of all the measured quantities and operative parameters by means of digital display on the front panel;
• high effectiveness and hence fast operation, due to digital processing of the input quantities;
• serial communication circuit;
• high reliability, assured by suitable checking actions and continuous monitoring of internal circuits;
• possibility to use a single relay as well for installations with several generators.
