Original Mebay DC90D MK2 AMF Generator Controller 4.3" TFT LCD Auto Mains Failure Generator Control Panel

Overview

This series of controllers is designed for diesel, gasoline and gas generator sets, handling start/stop control, parameter monitoring, fault detection and parameter configuration.

The controller features a 4.3-inch TFT color LCD screen displaying generator set parameters, with a brand-new original UI design showing both analog pointer-style gauges and digital readouts. The LCD can display multiple active fault statuses simultaneously, effectively protecting the generator set with automatic shutdown in abnormal conditions.

The built-in display interface supports Simplified Chinese, Traditional Chinese, English, Spanish and Russian — with custom language options available upon request. All parameters can be adjusted directly via the front panel keys, or monitored and configured from a PC through the USB or RS485 port. The controller is widely applicable to various types of generator set automation systems.
