The SGC 420/421 controllers are modern AMF genset controllers with a user-friendly HMI and full graphics LCD.
They include voltage and frequency measurement for mains and gensets, and electrical load measurement (true RMS).
Configurable analogue and digital inputs/outputs are provided for various features.
Modbus over RS-485 and CAN ports is available for remote communication.
Start and stop gensets remotely using the Remote start/stop function.
Deep sleep mode is a useful feature that extends the battery lifetime by suspending the normal controller functions of when the genset is off.
Monitoring engine safety, electrical load, site battery backup voltage and shelter temperature (to reduce fuel consumption).
Configure parameters from a PC using DEIF Smart Connect utility software. Connect to the PC through the controller’s USB Type B port.
In addition, the SGC 421 controller also includes an integrated electronic governing function.
