Description
LEROY SOMER R250 AVR FOR LEROY SOMER ALTERNATORS
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.Voltage regulation: around ± 0,5 %.

General Characteristics
* Voltage regulation +/- 0.5% at steady state and constant speed.
* Phase to neutral voltage sensing.
* The regulation quality is independant of load applied.
* Optimum management of impact loads using micro-processor technology.
* Suitable for high levels of vibration and harsh environments.
* Supply range/voltage detection 85 to 139 V (50/60Hz).
* Rapid response time (500 ms) for a transient voltage variation amplitude of gt; ± 20 %.
* Voltage setting P1.
* Stability setting P2.
* Supply protected with an 8 A fuse, slow action (supports 10 A for 10 s).
* U/F Fonction and LAM
* Operating at 50 Hz: (U/F gradient)
* Operating at 60 Hz: (U/F gradient)
* Specific operating
* R250 A.V.R. option
* Gradual voltage return function

Applications
Alternators LSA 42.2, 43.2, 44.2, 46.2, 47.2.
Compatible with the SHUNT excitation system.
