Mebay DC100D Genset Parallel Controller Diesel Generator Engine LCD Control Board CAN Communication Interface Generador Parts

I. Overview:

This series of controllers is specially designed for manual/automatic parallel system of multiple generator sets of the same capacity or different capacities. And it is suitable for a single generator set with constant power output and multiple generators in parallel. The generator set has the functions of automatic startup and shutdown/parallel operation, data measurement, and alarm protection.

4.3inch colorful LCD screen display with brand new UI design is adapted in this controller that the relative failures can be displayed directly.All the parameters can be displayed by simulated indicators and words. Besides, LCD screen can display various faults in the same time that the gen set will be stopped once it can’t work smoothly.

The gen set parallel controller utilizing the GOV (Engine Speed Governor) and AVR (Automatic Voltage Regulator) control function, the controller is able to synchronize and share load automatically; it can be used to parallel with other DC100D MK2 controller. DC100D MK2 controller accurately monitors various working states of the generator set. When the generator set works abnormally, it
automatically opens the bus bar and disconnects the bus, shuts down the generator set, and displays the fault status on the LCD. SAE J1939 interface enables the controller to communicate with various ECU (ENGINE CONTROL UNIT) which fitted with J1939 interface.

The controller has a built-in display interface of simplified Chinese, traditionalChinese, English, Spanish, and Russian, and the language interface can be customized according to customer requirements. All parameters of the controller can be adjusted through the buttons on the controller panel, or adjusted and monitored through the USB port or RS485 interface using a PC, which can be widely used in various types of generator set automation systems.
