Description

Products: 
     SX**0 generator regulator board is a brushless excitation system generator regulator board, excitation power derived directly from the generator terminals, and the machine does not function, AVR Generator Automatic Voltage Regulator. Detecting power input **0V / **0V. No product can be replaced. No substitute product. 
    SX**0 is a half-wave phase-controlled thyristor type Automatic Voltage Regulator (AVR) and forms part of the excitation system for a brushless generator in addition to regulating the generator voltage, AVR circuits including speed and sensing loss protection features. Excitation power is derived directly from the generator terminals. Positive voltage from the residue levels established in order to ensure efficient use of semiconductor voltage power circuit. AVR with the main exciter field winding and a stator winding for a closed-loop control of the output voltage and load regulation + / - 1.0%. 
      Apart from the main stator, AVR also derives a sample of the output voltage from the voltage winding of the object of control. In response to this sample voltage, AVR controls the power fed to the exciter field, so the main field, keeping machine output voltage specified limits, compensating for load, speed, temperature and power factor of the generator. 


Product performance and features: 
     1, voltage accuracy      2, in order to select the single-phase copper jumper **0 / **0VAC detection voltage 
     3 to choose *0/*0 Hz jumper copper 
     4, with the loss of the detected voltage protection circuit 
     5, with the low-frequency protection (UFRO) and the voltage slowly build function 
     6, with LED status indicator frequency is too low 
     7, can be copper jumper settings to suit different power generators 
     8, prominent features: a stable exchange circuit provides an adjustable negative feedback inhibition components including the prevention of sub-cycle peak voltage damage AVR components and reduce the amount of noise in the generator terminals. 
     9, a selling point: a low-pass filter to prevent the distortion of the waveform affect the operation of the AVR. 

The definition of the different colors: 
     1, these three kinds of colors mean: red Stanford's early products, the use of capacitors to WIMA, the quality is very good. Blue said late product, capacitor EPCOS, quality is also good. Gray is only the last 2 years, the capacitance of AV, and the packaging is different. 
     2, due to different capacity, the price is different 
     3, although prices vary, but the quality is similar. Just some maintenance staff always feel better in red, with red is also the most expensive.
