With ARM-based 32-bit SCM, highly integrated hardware, new reliability level. 480x272 TFT LCD with backlight, multilingual interface (including English, Chinese or other languages) which can be chosen at the site, making commissioning convenient for factory personnel; Improved LCD wear-resistance and scratch resistance due to hard screen acrylic; Silicon panel and pushbuttons for better operation in high-temperature environment; RS485 communication port enabling remote control, remote measuring, remote communication via ModBus protocol (RS485 communication port is needed); Equipped with SMS (Short Message Service) function. When genset is alarming, controller can send short messages via SMS automatically to max. 5 telephone numbers. besides, generator status can be controlled and checked using SMS(GSM port is needed); Equipped with CANBUS port and can communicate with J1939 genset. Not only can you monitoring frequently-used data (such as water temperature, oil pressure, speed, fuel consumption and so on) of ECU machine, but also control start, stop, raising speed and speed droop via CANBUS port(CAN BUS port is needed). Suitable for 3-phase 4-wire, 3-phase 3-wire, single phase 2-wire, and 2-phase 3-wire systems with voltage 120/240V and frequency 50/60Hz; Collects and shows 3-phase voltage, current, power parameter and frequency of generator or mains. For Mains, controller has over and under voltage, over and under frequency, loss of phase and phase sequence wrong detection functions; For generator, controller has over and under voltage, over and under frequency, loss of phase, phase sequence wrong, over and reverse power, over current functions;over current functions;
