Designed and built by Flight Systems - with over 35 years of generator control service experience and tech support. We know what fails and why.
Compare our Universal Voltage Regulator to regulators from Onan®, Basler®, Katolite®, Newage®, Delco®, and Marathon®.
The Model 480 Universal Regulator is designed to replace many obsolete, hard to get and/or expensive regulators found on older AC generators (alternators), with or without brushless exciters, up to approximately 200 KVA in size, within its field output ratings. It is easily retrofitted because of its small size and simplicity of connection, usually only four wires and sometimes five. By means of jumper-selectable voltage programming, the Model 480 covers virtually all voltages from 100 to 480 VAC, 50 or 60Hz, on single and three phase systems.
The Model 480 comes with a 2 year warranty and has another huge advantage, it's fully repairable. Most other replacement Automatic Voltage Regulators (and most OE's) are throw-away's. This is the one to stock.
