The Mecc Alte SR7 AVR is a full digital, on-board, automatic voltage regulator (AVR) that is suitable for all self-regulated alternators. It has a voltage supply of 40Vac - 270Vac (from auxiliary winding, output voltage or PMG) and a frequency range of 12Hz - 72Hz.
The SR-7 regulator is suitable for use with all Mecc Alte alternators and is a standard...
The TGE MX341 is an automatic voltage regulator (AVR) equivalent to the STAMFORD MX341 and that is compatible with a wide range of Stamford alternators. It is a two-phase sensing AVR that provides closed loop control by sensing the alternator output voltage at the main stator windings and adjusting the exciter stator field strength.
The Leroy Somer R449 AVR is a shunt-type automatic voltage regulator (AVR) designed for use with Leroy Somer AREP or PMG alternators. It is capable of maintaining the output voltage of the alternator within a tight range, even under varying load conditions.
