Product description:
SX**0 is a brushless generator excitation
system regulator board 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 brushless
excitation system generator in addition to regulating the generator
voltage, AVR sensing circuit including speed and loss of protective
functions. Excitation power is derived directly from the generator
terminals. Positive voltage created from residual levels to ensure
efficient use of semiconductor voltage power circuit. AVR with the
main stator windings and the exciter field windings to provide
closed-loop control of the output voltage and load regulation of +
/ - 1.0%.
Apart from the main stator, AVR voltage is
derived from a sample of the object from the control voltage output
winding. In response to this sample voltage, AVR controls the power
fed to the exciter field, so the main areas to maintain machine
output voltage within the specified limit, compensating for load,
speed, temperature and power factor of the generator.
Product performance and features:
1, the regulator accuracy <± 1%
2 to choose single-phase copper jumper
detection voltage **0/**0VAC
3 to choose copper jumper *0/*0 Hz
4, with the loss of detection voltage
protection circuit
5, with a low frequency protection (UFRO) and
voltage slowly build function
6, with a status LED indicates the 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 of
components including the prevention of damage to the sub-loop
voltage spikes AVR components and reduce the amount of noise in the
generator terminals.
9, the selling point: a low-pass filter to
prevent the distortion of waveforms affect the operation of the
AVR.
The definition of the different colors:
1, which is the meaning of three colors: red
for Stanford's early products, the use of capacitor WIMA, the
quality is very good. Blue indicates the latter product, capacitor
EPCOS, the quality is also good. Gray is the last two years before
that, the capacitance of AV, and the packaging is
different.
2, due to different capacitors, the price will
be different
3, although prices vary, but the quality is the
same. But some maintenance staff always feel better in red, red is
also the most expensive.
