Generator AVR R450 Generator Spare Parts Automatic Voltage Regulator R450 Leroy Somer Alternator
R450 AVR for Leroy Somer Genset controls the excitation current in order to maintain the output voltage of the alternator.
Features
• Check the rotating switch selection
• Start the engine and set its speed to a frequency of 48 Hz for 50 Hz, or 58 for 60 Hz.
• Check LAM operation: depending on the rotating switch selection.
• The R450 AVR is supplied in a casing designed to be mounted on a panel with dampers.
Maximum power supply: 15V-50/60HZ
Rated overload current:10A-10S
Electronic proctection
In the case of a short-circuit, the exacitation current is reduced to a value less than 1A after 10s
In the event of loss of voltage reference, the excitation current is reduced to a value less than 1A after 1s for AREP/SHUNT, 10s for PMG.
