Load control Module 4M
DFCC2 module allows, trough the Domino system, to manage the power absorbed by a single-phase electrical system, avoiding the interruptions of the electrical network caused by the simultaneous supplying of many loads with an excessive total power consumption; this module is a valid solution for the classification of a civil plant according to level 2 (V3 variant of the standard 64-8).
DFCC2 module can manage up to 8 distinct loads; many parameters for optimizing the module operation may be defined during the setting up.
DFCC2 constantly monitors the total active power absorbed by the connected electrical systems (on the considered phase) and, if its value exceeds a threshold fixed during the setting up, it starts the load shedding according to a well defined sequence until the total power returns under the threshold. The loads can be disconnected from the electrical network by the Domino power relay output modules (e.g. DF4RI).
BDTools support program allows to define the value for disconnection threshold (12kW max), the priority of each load and the related delay times. The shedding status of the 8 loads is reported by DFCC2 module by means of 8 LEDs placed on its front panel and by a buzzer that, if not desired, can be disabled. DFCC2 module also provides the main electrical measurements, allowing to display them on the suprvisor systems.
