LEORY SOMER AVR R449:

1.R449 SHUNT excitation system

The SHUNT excitation alternator is auto excited with a R250 voltage regulator.The regulator controls the excitation current according to the alternator's output voltage. With a very simple conception, the SHUNT excitation alternator does not have a short circuit capacity.

2.Characteristics

Voltage regulation: around ± 0,5 %.
Supply range/voltage detection 85 to 139 V (50/60Hz).
Rapid response time (500 ms) for a transient voltage variation amplitude of ± 20 %.
Voltage setting P1.
Stability setting P2.
Supply protected with an 8 A fuse, slow action (supports 10 A for 10 s).
