Function: 1. Voltage regulator: Automatic voltage regulator can control the field current to maintain the output voltage of the generator. 2. Better control: Specially designed dla AC generators with AREP or PMG excitation, this AVR ma high accuracy 0,5% RMS. 3. Reliable use: with an input voltage below 120 V AC, the voltage regulator enables 160 V DC and a maximum magnetic field output of 10 A. 4. Great fit: Highly compatible with AC LSA42.3, LSA43.2, LSA44.3 and LSA44.2 generators, wide range of applications. 5. Easy to install: ma small size and light weight, installation is very convenient do completion. . AUTOMATIC VOLTAGE REGULATOR R438 AVR 40-150V .
