Description

MX341 Permanent Magnet Generator type voltage regulator is a compatible replacement for Newage Stamford Mx341. There PMG used in AC permanent magnet machines UC, HC, LV series generator

Main features:

  1. Voltage regulation < ±1%
  2. For use in parallel operation
  3. Adjustable EXC TRIP, DIP, TRIM & DROOP functions
  4. Soft start voltage ramping
  5. Under frequency roll Off protection
  6. UFRO & over excitation LED indicators
  7. MX440 self excited brushless type genset voltage regulator with sensing input from 90 to 520VAC is a compatible replacement for Newage Stamford SX440 regulator.
  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 output voltage of the voltage regulator such as inconsistent voltage adjustment potentiometer clockwise , the output voltage increases ; and vice versa .
  2. the frequency setting of the engine speed adjusted 47HZ, UFRO potentiometer counterclockwise rotation , so that the indicator light-emitting diodes , can be transferred back to the engine speed .
  3. overcurrent less excited at the rated power of the generator , the rotating field trip potentiometer counterclockwise , 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 rotated clockwise about 5 degrees.

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 capacitance , the price is 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 .
