AVR R448 Automatic Voltage Regulator [LOCAL STOCK. FAST SHIPPING] FOR DIESEL ENGINE GENERATOR

1.Product description˖ Specifications: normal AVR supply power:2 auxiliary windings(X1,X2,and Z ,Z2). Shunt supply: 150v -50/60Hz Rated overload current:10A,10s. Electronic built-in (overload, short circuit, and loss of sensing)protection: lf 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 2.voltage taps at: Terminals 0-110v =95 to 140 v Terminals 0-220v =170 to 260 v Terminals 0-380v =340 to 520v Output Voltage adjustment by using pot P2 Other sensing voltages by using an adapting other3.transformers: Current sensing(parallel operation)CT 2.5 VA class 1 secondary current xxx/1(optional). 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.
