Enertrak AMF 9920 Smart AMF Controller 3-Phase Genset Automatic Mains Failure

Enertrak AMF 9920 is a smart 3-phase AMF controller made for generator sets. It helps control the genset when the main power supply fails. The controller can automatically start the generator and transfer the load to the generator.

When mains power returns, it can transfer the load back and stop the generator after the required sequence. This makes it useful for automatic generator control in many power backup systems.

Key Features

• Engine parameter monitoring
• Graphical LCD display
• Remote start and stop support
• USB communication
• RS-485 communication with Modbus support
• CAN communication with J1939 support
• Generator overload protection
• Over and under voltage protection
• Frequency monitoring and protection
• Battery voltage monitoring
• Fault warnings and shutdown protection
• Event logging
• Optional GPRS-based remote monitoring
• Compact design for panel installation

Applications

The Controller Enertrak AMF 9920 is designed for automatic generator control applications where reliable mains failure detection and genset operation are needed.

It can be used for:

• Diesel generator sets
• Automatic mains failure panels
• Generator control panels
• Industrial power backup systems
• Commercial power backup systems
• Remote genset monitoring
• Single and multi-set generator systems when supported by the connected monitoring setup

Technical Benefits

The controller supports a wide DC supply range of 8 V to 32 V. Generator and mains voltage can be measured from 70 V to 415 V AC line-to-neutral and up to 719 V AC line-to-line, with a frequency range of 10 Hz to 70 Hz.

It also provides communication options such as USB, RS-485 and CAN. The RS-485 interface supports Modbus communication, while CAN communication supports J1939 for engine monitoring integration. GPRS connectivity can be used with compatible Enertrak modem and remote monitoring solutions.

Industry Usage

The AMF 9920 can be used in applications where generator backup needs automatic control. Typical use areas include industrial facilities, commercial buildings, generator panels, infrastructure sites and other installations that depend on DG sets for backup power.

Its programmable protection functions allow important settings such as voltage, frequency, overload current and cooling-down time to be adjusted according to the genset application.

Performance Advantages

The controller provides clear information through its LCD interface and helps operators monitor important generator parameters. Its protection functions can detect abnormal conditions and provide warning or shutdown actions.
