  • Type:     R448
  • Product Summary:
  •       The circuitry of the R448 Automatic Voltage Regulator (AVR) provides closed loop control of the alternator output voltage by regulating the exciter field current. The primary winding has a voltage in ratio to that of the alternator (characteristic shunt), the next has a voltage in proportion to the stator current (compound characteristic: booster effect)....

Product description:

R448 is a special AVR for leroy somer generators.Generator output voltage is adjusted by using the voltage adjustment potentiometer on the AVR;Power factor regulator (2nd function) and voltage equalization before paralleling with the mains (3rdfunction).We strictly control the process and raw materials. Every product is made of imported or well-known brand materials. It undergoes 12 hours on-line aging test with rated current.The highest 85℃can work to meet the military standards.
