电压调节R448

Voltage Regulator R448 R448voltage regulator of a sealed electronic devices, by adjusting the excitation current in order to stabilize the output 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 Voltage sensing 5VA insulated transformer with input voltages taps at: Terminals 0-110V=95-140V Terminals 0-220V=170-260V Terminals 0-380V=340-520V We still supply AVR: 1.
