MX321 diesel generator voltage regulator

Products: 

      MX321 uses a permanent magnet generator exciter regulator board as excitation power, higher voltage stability. Load characteristics, and the machine has a function. 

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

      2, can be replaced SX440, MX341 product, the difference in the MX321 is a permanent magnet as the excitation power exciter, SX440, MX341 is self PMG excitation as the excitation source. 

Product performance and features: 

      1, voltage accuracy <± 0.5% RMS 

      2, can be used in parallel unit 

      3, three-phase RMS voltage detection 

      4, when a short circuit that automatically limits the current output 

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

      6, with LED indication over low-frequency, high-voltage and over-excitation state 

AVR adjustment (adjusted at the factory, the user only when necessary, adjusted as follows): 

     A voltage regulator such as the output voltage does not match the voltage adjustment potentiometer clockwise, the output voltage increases; otherwise reversed. 

     2 frequency setting the engine speed is adjusted 47HZ, UFRO potentiometer counterclockwise rotation, so that the indicator light-emitting diodes, can be transferred back to the engine speed. 

     3 overcurrent cut the generator excitation at rated power, rotating field trip potentiometer counterclockwise, so that the indicator light-emitting diodes, and then rotated about 5 degrees to shun. 

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

    The definition of the different colors: 

    1 This is the meaning of three colors: red for 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 capacitance, 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. 

Specifications: 

     Operating voltage range: 150 ~ 265 V 

     Maximum current is: 6A 

     DROOP: set pressure dropped to 5% (PF = 0) TRIM:. Optimize voltage correction sensitivity EXC TRIP:. Set too exciting trip points. 

                                                         DIP: adjust the voltage / frequency scaling DWELL:. Setting response time / frequency ratio of I / LIMIT:.. Setting the stator current output limit OVER / V: over-voltage trip point is set. 

                                                         RAMP: setting no-load voltage slowly rise time RMS:. Rms value of the generator set. 

     Prominent feature special / characteristic adjustment knob: VOLT: adjust the voltage STAB:. Adjustment stability UFRO:. Adjust the low-frequency protection turning point.
