General Description / Specifications

The Leroy Somer R726 module has 4 main uses:

1) Helps regulate the voltage.
2) Power Factor Regulation feature.
3) Equalization of incoming voltages.
4) Enables efficient parallel operations.

This regulator is compatible with the R438, R448, R129/R128A, R129 voltage regulators.

The additionnal Module R 726 enables to operate the following automatic voltage regulators (the 1ST FUNCTION being VOLTAGE REGULATION) into a so said "4 FUNCTIONS" regulation system :
. the 2nd FUNCTION being the POWER FACTOR ("COS ϕ ") REGULATION, using an additionnal C.T., when
the alternator is paralleling with the mains.,
. the 3rd FUNCTION being the BALANCE (EQUALIZATION) OF VOLTAGES before paralleling (U = U) which is generally realised by a synchronizer controlling the remote voltage trimmer of the automatic voltage regulator,
. the 4th FUNCTION (working with the 3rd) is parallel operation with other(s) alternator(s) equpped with the same module R726 during voltage equalization before paralleling with the mains.

R 438 LS AREP or ARPI
R 448 AREP or ARPI or ATR
The module must be installed close to the voltage regulator (inside or outside of the machine).
It is connected to the voltage regulator in lieu of the remote voltage potentiometer of the AVR.
This remote voltage trimmer may be then connected if necessary to the Module R 726 .
THE OTHER FUNCTIONS OF VOLTAGE REGULATOR (UNDERSPEED PROTECTION, EXCITATION LIMIT,
OVERCURRENT...) ARE KEPT.
