Product Description

 R250 AVR controls the excitation current according to the alternator's output voltage. With a very simple conception, the shunt excitation alternator is auto excited with a R250 and excitation alternator does not have a short circuit capacity, voltage regulation: around ±0.5%.

1.Leroy Somer Automatic Voltage Regulator R250
2. Suits leroy somer brushless alternator
3.Analogic Automatic Voltage Regulator with transistor

4.Applications Alternators LSA 42.2, 43.2, 44.2, 46.2, 47.2. Compatible with the SHUNT excitation system. The R250 is in Compliance with: IEC, VDE, NEMA, BS, CSA, UL508 CE low voltage.

 

 Voltage regulation Around ± 0.5 %
 Supply range 85 to 139 V
 Potentiometer for voltage setting 1000Ω /0.5W min. setting range ±5%
 Operating at 50 Hz Threshold at 48 Hz without LAM forimpactsbetween 30 and 40% of the rated 
 Load
 Threshold at 48 Hz with LAM 13% forimpacts between 40 and 70% of the rated 
 Load.
 Threshold at 48 Hz with LAM 25% for impacts > 70% of the rated load
 Operating at 60 Hz Threshold at 58 Hz without LAM forimpacts between 30 and 40% of the
 Rated load
 Threshold at 58Hz with LAM 13% for impacts 40 and 70% of the rated load
 Threshold at 58Hz with LAM 25% for impacts > 70% of the rated load
 Specific operating Threshold at 57Hz without LAM for speed variations at a steady state > 2 Hz
 Threshold at 65Hz without LAM for speed and tractelec / gearlec (U/F gradient)
 Special: the factory setting 48Hz 2U/F gradient; a special programme is 
 Possible on request.
 Threshold at 47.5 Hz without LAM for speed variations at a steady state > 2 Hz
