Features

R 450 is an analog A.V.R..It is designed for alternators with a SHUNT, AREP or PMG excitation .

R 250 controls the excitation current in order to maintain the output voltage of the alternator.R 250 is performant in terms of voltage regulation, simple to set , to use and is reliable.Rotating switch for U/f, LAM, excitation type and voltage sensing are available.

Technical parameters

- Voltage regulation : ± 0.5 %.

- Under-speed protection by function :

1 U/f (LAM : OFF).

2 U/f (LAM : MODE1).

Auto-adaptating LAM + 2 U/f (LAM : MODE 2).

- Nominal excitation current : 6A.

- Maximum excitation current : 10A during 10 s.

- Supply range 150V (50Hz/60Hz).

- Voltage detection : =<530V

- Protection : fuse fast 10A.

- Protection on load, short-circuit and voltage reference loss
