Maxgeek R150 Diesel Brushless Generator AVR Automatic Voltage Regulator Excitation Voltage Stabilizer

Maxgeek R150 Diesel Brushless Generator AVR Automatic Voltage Regulator Excitation Voltage Stabilizer

Description:
-The automatic voltage regulator is a compact, high performance encapsulated unit. The AVR incorporates latest technology and efficient semiconductor to achieve a high degree of miniaturization when applied to 30 and 10 AC brushless generator within its input and output limits, the unit offers excellent reliability. The AVR supplies DC excitation to the exciter field of a brushless generator to keep the terminal voltage within close limits from NO-LOAD to FULL LOAD.
-The recovery time on sudden loading is likely to be around 0.5 sec. to recover 98% of the rated voltage. Please note that the transient performance like voltage dip and recovery time are mainly decided by the generator and exciter design parameters. Best performance from the regulator can be obtained by keeping full load excitation around 60V DC.
