Products:
     MX341 generator for single-phase voltage regulator board detection PMG Generator Automatic Voltage Regulator (automatic voltage regulator). Since PMG as using exciter excitation power, voltage stability. Load good, with and machine functions. There PMG used in AC permanent magnet machines UC, HC, LV series generators.
     1, can be replaced MX321, but must change the line, the function is not so perfect, but basic functions are similar.
     2, can replace the MX321 product, the difference in the MX321 is a permanent magnet as the excitation power exciter, MX341 is self PMG excitation as the excitation source.

Product performance and features:
       1, voltage accuracy <± 1%.
       2, can be used in parallel units, short circuit can automatically limit the current output.
       3 to select jumper copper 50/60 Hz.
      4, when a short circuit can automatically limit the current output.
      5, with DIP, DROOP and over-excitation trip adjustment function, with the low-frequency protection (UFRO) and the voltage slowly build function.
      6, with the low-frequency protection (UFRO) and the voltage slowly build function.
      7, with LED indicating low frequency and over-excitation state, capable copper jumper settings to suit different power generators, MX341 can be used in parallel units, copper jumper can be set to match the different power generation machine.
      8, the selling point: DROOP and machines, auxiliary input, over-excitation voltage protection.

AVR adjustment (adjusted at the factory, the user only when necessary, adjusted as follows):
      1, the voltage regulator such as the output voltage does not match the voltage adjustment potentiometer clockwise, the output voltage increases; otherwise reversed.
      2, the 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, rotary potentiometer counterclockwise field trip, so that the indicator light-emitting diodes, and then rotated about 5 degrees to shun.
      4, overvoltage counterclockwise rotation overvoltage adjustment potentiometer, so that the indicator light-emitting diodes, and then clockwise about 5 degrees.

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.

Specifications:
      Power input: 170-220V AC, 3-phase 3A (PMG)
      Sensor Detection: 170-250 V AC single phase
      Output: voltage 120VDC (maximum)
                  Current: 3.7A (continuous) 6A / 10S (instantaneous)
      Protection: Built-in low-speed, over-excited, LAM,
      Adjusted rate: better than 1% (for brushless generator)

       Patented design: ultra-low voltage from magnetic, fast response, voltage more stable. The key loop using military-grade high stability components, temperature drift of less than 0.05% / ℃. Multiple independent protection circuit design, more safe and reliable.
       We promise: quality issues in a lose three!
