MX341 is a two phase sensed Automatic Voltage Regulator(AVR)and forms part of the exciation system for a brush-less generator.Excitation power is derived from a three-phase permanent magnet generator(),to isolate the AVR control circuits from the effects of nonlinear loads and to reduce radio frequency interference on the generator terminals.sustained generator short circuit current is another feature of the system. The AVR senses the voltage in the main generator winding and control the power fed to the stator and hance the main to maintain the generator output voltage within the specified limits,compensating for load sprrd,temperature and power factor of the generator The AVR has the faclity for droop CT connection,to allow parallel running with other similarly equipped generators Colour:Black Material:metal +PC Size:15.3*13.9*3.9cm Package Contents: 1 x Voltage Regulator 1 x Manual Only the above package content, other are not included. Note: Light and different displays may cause the color of the item in the a little different from the real . The measurement allowed is +/- 1-3cm.
