Main Power Supply 6M
DFPW2 module generates the proper power supply required by the modules connected to Domino bus. To ensure proper operation, the input voltage of DFPW2 module must be 230Vac 50Hz.
DFPW2 performs an electronic protection with self-restoring function; the protection breaks off the current at the output terminals when an overload or a short circuit occurs on the bus. DFPW2 can supply up to 50 modules of Domino family (see table for exceptions).
Depending on the installed modules, on the topology of the system and on the bus wires size, more DFPW2 modules may be installed in different locations, in order to distribute them along
the bus and minimize the voltage drop.
When connecting more DFPW2 modules on the same bus, it is important to take care of the polarity (both L/N and +/-); in addition, a unique breaking switch for all DFPW2 has to be installed. For 3-phase networks, all installed DFPW2 related to the same bus must be connected to the same phase.
