Automatic Genset Controller (AGC-4 & AGC-4 Mk II) – Features, Benefits, and Upgrade Guide

Introduction to Automatic Genset Controllers

An Automatic Genset Controller (AGC) is an advanced control and monitoring unit designed to manage generator sets with precision and efficiency. It automates critical operations such as start/stop sequences, load sharing, synchronization, protection, and communication with other power management systems.

Among industry-leading solutions, the DEIF AGC-4 has long been trusted for reliable generator set control. However, DEIF has now introduced the AGC-4 Mk II, the improved and recommended replacement product. While AGC-4 spare parts are still available, the Mk II offers advanced features aligned with modern power management needs.

AGC-4 Automatic Genset Controller – Overview

The AGC-4 was designed to provide full genset control in single and multiple generator applications. Key features include:

• Automatic start and stop sequences for smooth operation.

• Load sharing & synchronization between multiple generators.

• Protection functions such as over/under voltage, frequency, and engine alarms.

• User-friendly interface for monitoring and operation.

• Remote monitoring & communication for efficient power management.

This made the AGC-4 an essential tool in power plants, standby power systems, and critical industrial applications.

Transition to AGC-4 Mk II – The Recommended Upgrade

DEIF now recommends the AGC-4 Mk II as the replacement for the AGC-4. This transition is part of their commitment to delivering smarter, more future-ready genset controllers.

Why Upgrade to AGC-4 Mk II?

• Extended functionality: Advanced communication protocols for integration with modern power systems.

• Enhanced cybersecurity: Secure data handling and remote connectivity.

• User-friendly design: Improved display and intuitive navigation.

• Sustainable solution: Longer product lifecycle and better support.

• Compliance with modern standards: Ensuring system reliability and compatibility with future requirements.

While the AGC-4 is still supported with spare part units, industries planning long-term operations should migrate to the AGC-4 Mk II for maximum reliability.
