Profesional supply all these generator spare parts,avr automatic voltage regulator controller solenoid actuator speed governor battery charger and etc.
R250 AVR controls the excitation current according to the alternator's output voltage. With 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%.It applies to brushless generator from 20-100kw.
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.
