This automatic controller, integrating digital, intelligent and network techniques, is used for automatic control and monitoring system of genset. It can carry out functions of automatic start/stop, data measurement, alarm protection and three remote (remote control, remote measure and remote communication). Users can monitor the genset and inquire the genset running status, the event log, as well as configure the parameters via cloud server by phone APP (ISO or Android) and computer terminal equipment.
Alarm & shutdown items are included:
Low Coolant Level
High coolant temperature
Low oil pressure
Low output frequency
High output frequency
Low output voltage
High output voltage
Low Fuel Level
Emergency stop
Crafted as a silent-type unit, the 40kW generator set incorporates a 2mm thick galvanized steel enclosure to minimize operational noise, achieving an impressive noise level of 75dB(A) at 7 meters. This design ensures compliance with stringent environmental standards while enabling installation in noise-sensitive areas. Additional safety and convenience features include a Suyang 125A circuit breaker for enhanced electrical protection and an integrated 8-hour base fuel tank with a fuel level sensor for real-time monitoring.
