R725A - Leroy Somer

PurposeThe additionnal Module R 725A enables to operate the following automatic voltage regulators (the 1ST FUNC- TION being VOLTAGE REGULATION) into a so said "3 FUNCTIONS" regulation system :The 2nd FUNCTION being the POWER FACTOR ("COS Ì_å?????????????åÎÌ_ ") REGULATION, using an additionnal C.T., when the alternator is paralleling with the mains.,The 3rd FUNCTION being the BALANCE (EQUALI- ZATION) OF VOLTAGES before paralleling (U = U) which is generally realised by a synchronizer controlling the remote voltage trimmer of the automatic voltage re- gulator,
