The SGC 420 controller is designed for AMF (automatic mains
failure) applications with a genset and offers fuel-saving features
such as advanced battery charge management and temperature
monitoring.
The SGC 420 controller contains all the functions you need to
protect and control a genset, a genset breaker, and a mains
breaker. It is capable of monitoring a site battery to reduce fuel
consumption, and it can monitor shelter temperature and several
engine and alternator parameters. You can start and stop gensets
remotely, and the SGC 420 is suitable for a wide range of
applications including AMF (automatic mains failure), site battery
monitoring, engine drive, and island (off-grid) mode.
Several measurement functions
The controller allows you to measure 1-phase, 2-phase, 3-phase, and
split-phase voltage, frequency, load current, and power factor,
engine safety parameters such as engine temperature, oil pressure,
and fuel level, fuel theft protection, and the engine battery. In
addition, it can measure site battery backup voltage and shelter
temperature to reduce fuel consumption. It features CAN bus and
Modbus communication plus nine configurable inputs, eight analogue
inputs, and seven configurable digital outputs.
User-friendly display
You can configure parameters from a PC using the DEIF Smart Connect
utility software, or from the unit’s user-friendly, full graphics
LCD display. The backlit display can show values and alarms in
several languages including English, Chinese, and Spanish.
Deep sleep extends battery life
The SGC 420 has a practical deep sleep function that extends the
battery life by suspending normal controller functions when the
genset is off.
