Product Description
Generator Automatic Voltage Regulator Basler AVR BE350
General Features
 | Generator Automatic Voltage Regulator Basler AVR BE350 The BE350 instruction manual specifies a 190–240 Vac single-phase power and sensing input, 50/60 Hz, ±10%; see the manual for the separate 171–264 Vac power-input range. The BE350 Revision D manual covers exciter-field requirements, corner-frequency selection and installation. Confirm the generator system and wiring against the correct manual before replacement. |

Generator AVR Not Producing Voltage: 5 Causes and How to Test Them
A generator that runs but produces no power is most often an excitation or AVR problem. Here are the five causes we see most in the field, the multimeter check for each, and when the regulator itself needs replacing.

The BE350 manual lists 190–240 Vac, ±10%, single-phase, 50/60 Hz, ±10% for the power input and sensing input (common with the AC power input). It separately gives an acceptable power input range of 171–264 Vac in the installation section. Verify the generator circuit against the applicable manual.
The manual specifies a minimum exciter-field DC resistance of 21 Ω. A field below this limit requires evaluation under the manual's instructions before installation.
The manual lists 3.5 Adc at 73 Vdc (255 W) maximum continuous output and 5 Adc at 105 Vdc (525 W) one-minute forcing with 240 Vac power input. Verify the alternator and excitation circuit against the manual.
The manual says the factory jumper is set for 50 Hz operation with a 45 Hz corner frequency. For 60 Hz operation and a 55 Hz corner frequency, move the corner-frequency jumper to the 60 Hz terminal, following the manual.
A Basler BE350 instruction manual (Revision D, dated July 2026) was supplied for this product mapping. Ask support to confirm the exact model-specific document and revision before installation.
Send the BE350 nameplate, generator voltage and frequency, exciter-field resistance, and the existing regulator terminal/control layout. Confirm wiring against the BE350 manual before energizing.
