R448 A.V.R.
Characteristics
Shunt power supply: max 150V - 50/60 Hz
Rated overload current: 10A - 10s
Electronic protection:(in the event of
overload, short-circuit,loss of voltage sensing)
this acts to restore the value of the excitation
current to 1A after 10 s. The alternator must be
stopped (or the power switched off) in order to
reset the protection.
Fuse: F1 on X1, X2.10A;slow - 250V
Voltage sensing : 5 VA isolated via trans-
former
0-110 V terminals =95 to 140 V
0-220 V terminals =170 to 260 V
0-380 V terminals =340 to 520 V
for other voltages,a transformer should be
used.
Voltage regulation ± 0.5%
Normal or rapid response time via jumper
