The Marathon DVR2400 is a high‐end digital automatic voltage regulator designed for use in brushless generator systems. It constantly monitors the generator’s output and dynamically adjusts the exciter field current to deliver precise, stable voltage — ensuring your equipment operates safely and reliably under varying load and condition changes.

? Key Features

• Utilises digital control with advanced regulation modes (AVR, reactive power/VAR, field current regulation) for best-in-class performance.

• Maintains excellent voltage stability (typically around ±0.25% under load) even with nonlinear or fluctuating loads.

• Allows single-phase or three-phase generator sensing, field current sensing, and provides generous output capability for exciter-field control.

• Offers multiple protection features: over-excitation shutdown, under-voltage/over-voltage, sensing fault detection, reverse power shutdown, regulator over-temperature shutdown.

• Designed for modern generator applications: supports accessories such as front-panel human-machine interface (HMI), software configuration, communication links for monitoring and control.

• Suitable for retrofitting older analog regulators in existing systems, enabling improved performance without full system redesign.
