Regulador Automático de Voltaje (AVR) Modelo: R448

SPECIFICATION  

 Normal AVR supply power, 2 auxiliary windings 

(X1, X2, and Z, Z2)

Shunt supply : 150 - 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 then 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 

Voltege sensing: 5VA insulated transformer with input volge taps at:

Terminals 0-110V= 95 to 140V

Terminals 0-220 V = 170 to 260 V 

Terminals 0-380 V = 340 to 520 V 

Output voltage adjustment by using pot P2 

Other sensing voltages by using an adapting other transformers 

Current sensing (parallel operation) CT 2.5 VA class 1 secondary current xxx/1 (optiona).

Adjustment  of quadrature droop with pot P1 

Under-speed (U/F) and LAM protection: for knee frequency adjustable use P4.

Excitation over current adjustment use P5: 4.5 to 10A 

For 50/60 Hz (U/F) selection use jumper ST3.

SPECIAL APPLICATIONS 

 Field de- energizing 

Cutting excitation current is accomplished by switching off the supply power to AVR (1 lead on each auxiliary winding)

Contacts capacity : 10A. 250V AC 

This is the same connection used to reset internal protection of AVR.
