R448 AVR Automatic Voltage Regulato

AVR R448 FOR DIESEL ENGINE GENERATOR, GOOD QULAITY. 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 0-110v95 to 140 v Terminals 0-220v170 to 260 v Terminals 0-380v340 to 520v Output Voltage adjustment by using pot P2 Other sensing voltages by using an adapting other. 3. 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 frequ
