Product Description

AVR R250 Generator Standard Automatic Voltage Regulator

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 ashort circuit capacity, voltage regulation: around ±0.5%

 

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
