VR R448,Automatic Voltage Regulator
MODEL: AVR-448
Description
AVR R448
Description---- Input voltage: 70-140V AC, (PMG, or auxiliary
winding, single, three phases)
Reaction is measured : 90-480V AC
MAX. output :DC 10A 125V
Function: Built-in low-speed , over excitation
LAM,
REGULATION: +/-0.5%
R448 voltage regulator of a sealed electronic devices, by adjusting the excitation current in order to stabilize the output voltage of the brushless generator.
Generator output voltage is adjusted by using the voltage adjustment potentiometer on the AVR. Cutting excitation current is accomplished by switching off the supply power to AVR.
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
