A.V.R. R 438

The R 438 is an analogic Automatic Voltage
Regulator with transistor.

Applications

Main characteristics

Voltage regulation +/- 0.5 % at steady state and
constant speed.
Phase to phase voltage sensing.
Control by transistor means the regulation
quality is independant of load applied.
Integrated "LAM" system to cope with increased
loads applied to the engine
(activated by a wire strap).
Suitable for high levels of vibration and harsh
environments.
The R 438 is compatible with other modules
giving additional functions.
(parallel operation, 3 phase sensing ...)
