Multiquip 0601820602 Automatic Voltage Regulator

The Multiquip 0601820602 Automatic Voltage Regulator is a genuine OEM component designed for DCA series ultra-silent and super-silent diesel generators, including the DCA125USI3CAN, DCA70USI2, DCA25SSIU3, DCA45SSIU4, DCA70SSIU2, DCA125USI, DCA25USIXF, DCA25USI2XF, DCA85USJ2, DCA150SSI, DCA150SSIU, DCA250SSI, DCA70USI3CAN, DCA150SSCU4i, DCA40SSKU, DCA40SSKU4i, MQP56, DCA45, DCA45SSKU3, DCA25USI2, DCA45USI2, DCA45SSKU, DCA250SSI-3, DCA25USI4CAN, and DCA25USI4CAN (FR). As a direct OEM replacement, part 0601820602 is built to the same specification as the original component, ensuring stable electrical output across the full generator load range. If you are servicing a DCA series unit and need a dependable, plug-in replacement AVR, this is the correct part.

Key Features

• Stable Output Regulation — Maintains consistent voltage delivery under varying load conditions, protecting connected equipment from damaging surges or sags.
• Genuine OEM Construction — Manufactured to Multiquip's original electrical specifications, including correct sensing range, excitation output, and response characteristics for DCA series alternators.
• Direct-Connect Replacement — Matches original harness connectors and mounting points on compatible DCA generators, allowing straightforward installation without modification to wiring or mounting hardware.
• Broad DCA Series Compatibility — Confirmed fitment across a wide range of ultra-silent and super-silent DCA models, from compact DCA25 units through heavy-duty DCA250SSI configurations.
• Electrical System Integrity — Using a correctly rated AVR protects the alternator windings and downstream load circuits from the sustained overvoltage or undervoltage conditions caused by a failed regulator.

The Automatic Voltage Regulator continuously monitors the generator's AC output and adjusts field excitation current in the alternator to hold output voltage within a stable, usable range regardless of changes in load or engine speed. Without a functioning AVR, generator output voltage becomes erratic, which can damage sensitive electrical equipment connected to the unit and cause the alternator windings themselves to overheat. Replacing a failed or degraded AVR with the correct OEM part restores precise voltage control and protects the full electrical system of the generator.
