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.
