Capable AMF and Autostart genset controller with 3 phase (RMS) mains voltages and 3 phase (RMS) generator voltages and currents monitoring. Integrated J1939 Canbus interface to electronic engines, and traditional interface for non-electronic engines.

GC315 is suited for managing the most common three-phases generator applications (Single Prime Mover and Single Stand-by gensets).

Extensive input and output capability with optional communication interfaces (Plus and Link 5G ready versions), make this an extremely powerful single genset controller.

The adjustable parameters of the controller allow the use of this device for standard and customized tasks, can be directly set with the controller’s keyboard, or using the free software tool (BoardPrg3), available on SICES’ Website.

A version with built in GPRS/GPS tracking (GC315Link 5G) is particularly suited for mobile or rental applications, where asset tracking and monitoring is required.

Further details
GC315Link 5G has built in global 5G modem with global 2G fallback capability, which also embeds the GNSS localization system (GPS/GLONASS/BD) to provide a high availability solution that offers industry-leading accuracy and performance.

GC315, in all versions, is able to measure the mains frequency and compute the mains power, also when the load is connected to the mains itself. It’s also able to measure the neutral of mains and generator voltages.
Thanks to the separated push buttons, one for the MCB (Mains Circuit Breaker) and one for the GCB (GeneratorCircuit Breaker), the control of the genset in manual mode becomes easier.
