Units with catalog number starting with:
10 are self cooled
11 are forced-air cooled
Regulators can be modified at factory for 50
Hz operation with appropriate de-rating of
voltage.
*Capable of carrying current corresponding
to rated kVA when operated at 7200/12470
volts ground wye.
OPERATION AT LESS
THAN
RATED VOLTAGE
JFR regulators may be operated at less
than the voltage for which they were de-
signed. All system voltages for which
control system taps have been provided
are shown on the nameplate. When this
is to be accomplished it may be neces-
sary to reconnect particular leads at the
upper 19-pin terminal block as illustrated
on page 5. When operating the regulator
at reduced voltage it must be noted that
the regulator carries a maximum current
rating which rules regardless of the
voltage (see table at right). It may
therefore be necessary to operate the
regulator at less than its nameplate kVA
rating.
