Original Leroy Somer AVR R449 Voltage Regulator R449
R449 voltage regulator of a sealed electronic devices,by adjusting the excitation current in order to stabilize the output voltage of the brushless generator.
Specifications |
Normal AVR supply power: 2 auxiliary windings |
Shunt supply:150V - 50/60Hz |
Rated overload current: 15A, 10s |
Electrionic built-in(overload, shour circuit, and loss of sensing) prodtection: If Excitation current raises over 10 Amps for more than 10 seconds, excitation current will drops automatically to about 1A. To reset AVR protection, generator must be stopped(or by cutting supply voltage to the AVR). Protection of power inputs by fuses F1 |
voltage sensing: 5VA insulated transformer with input voltage taps at: Terminals 0-110V=95-140V Terminals 0-220V=170-260v Terminals 0-380V=340-520V Load current 7A overload current 15A,10s |
