Overview
The UVR6 is an Automatic Voltage Regulator (AVR) that maintains the generator output voltage within precise limits by controlling the exciter field current. It continuously samples the generator output voltage and adjusts excitation to compensate for load changes, engine speed variations, and temperature drift.
Key Features

Selection Advice The UVR6’s primary characteristic is the smallest form factor. When generator control box space is tight (small portable generators, vehicle-mounted generators), the UVR6 is the only option that fits. Only 4A current with average voltage adaptability — if space is not an issue, the SR7’s 6A output and wide voltage range offer broader applicability. The DER1 is the digital upgrade version.
