Leroy Somer AVR R448
Leroy Somer AVR R448,AVR R448 for Leroy somer generator
R448 voltage regulator of a sealed electronic devices, by adjusting the excitation current in order to stabilize theoutput voltage of the brushless generator.
Specification
|
Normal AVR supply power: 2 auxiliary windings |
|
Shunt supply: 150V - 50/60Hz |
|
Rated overload current: 10A,10s |
|
Electronic built- in(overload, short circuit, and loss of sensing) protection: 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 |
