Product Overview:
EP4300 Engine Controller is used for the control or data display (CAN instrument) of engines, especially for the electric-controlled engines to realize start/stop, speed control, data measurement, and alarm display of the engine. It fits with colour LCD display, optional Chinese and English, which is reliable and easy to use.

EP4300 Engine Controller applies 32-bit microprocessor technology, realizing precise measuring of many parameters, value adjusting and threshold setting etc. functions. A majority of parameters can be adjusted from the front panel. All parameters can be adjusted via USB or RS485 port by PC. With compact structure, simple wiring, and high reliability, it can be used in various engine automation systems.


Applies ARM-based 32-bit SCM, high integration of hardware;  

4.3-inch colour LCD display, resolution 480x272 with adjustable backlight (the backlight can be adjusted by automic or manual), optional Chinese and English, which can be chosen at the site, making commissioning convenient for factory personnel;

Silicon panel and pushbuttons, hard screen acrylic for screen protection;

Fitted with CANBUS port to communicate with J1939 engines, not only can monitor the frequently-used data (such as water temperature, oil pressure, engine speed, fuel consumption and so on, but also control the start/stop of the engine through CANBUS port;

3 programmable analog sensor inputs, the programmable sensor 3 input can be directly connected to resistance, voltage or current sensors, while other sensor inputs can only be connected to resistance sensor;

More kinds of curves of temperature, oil pressure, fuel level can be used directly and users can define the sensor curves by themselves;

Precision measure and display parameters of engines: speed, battery voltage, charger voltage, total start time and start attempts, etc.;

Three crank disconnect conditions (speed, oil pressure, speed+oil pressure) are optional;

Wide power supply range, suitable to different starting battery voltage environment;

Sealed enclosure design, the whole unit protection can reach IP65;

Modular structure design, flame-retardant plastic shell, pluggable water-proof connector, built-in mounting, compact structure with easy installation.
