Standford generator regulator, brushless automatic voltage regulator, AVR, MX321-2 excitation regulator

MX321 generator regulator adopts permanent magnet exciter as excitation power supply, and the voltage stability is higher. Load characteristic is good, has the parallel function.

1, can be replaced by SX440 and MX341, but must change the line, the function is not so perfect, but the basic functions are similar.

2, can replace SX440, MX341 products, the difference in the MX321 is the permanent magnetic exciter as excitation power, SX440, MX341 is from the PMG excitation as excitation power supply.

Product performance and characteristics:

1 、 regulation accuracy < < 0.5% RMS

2. Can be used in parallel units

3 、 three-phase RMS voltage detection

4 、 short-circuit current can automatically limit the current output

5, with UFRO, OVER/V, I/LIMIT, RAMP, DIP, DWELL, DROOP, RMS, TRIP, EXC, and other regulatory functions.

6 、 indication of over frequency, over voltage and over excited state by LED

AVR adjustment (factory has been adjusted, users only need to make the following adjustments when necessary):

1 voltage adjustment, such as the output voltage does not match, clockwise rotation voltage regulator potentiometer, the output voltage rise; otherwise, the -.

2 frequency settings, the engine speed to 47HZ, counterclockwise rotation UFRO potentiometer, so that the indicator light, back to the engine speed can be.

3 flow reduction of the generator excitation under rated power, counterclockwise rotational excitation release potentiometer, the indicator light emitting diode, then clockwise about 5 degrees can be.

4, over-voltage protection, counterclockwise rotation, overvoltage adjustment potentiometer, so that the indicator light emitting, and then clockwise rotation of about 5 degrees.

About the definition of different colors:

1., the meaning of these 3 colors is: red represents Standford's early products, the capacitor used for WIMA, quality is very good. Blue represents late products, capacitors of EPCOS, and good quality. Gray is nearly 2 years ago, the capacitor is AV, and the packaging is also different.

2. because of the different capacitance, the price is also different
