Specially designed to meet the needs of OEMs and genset packagers, the SGC 420 Mk II single genset controller contains all the functions you need to protect and control a genset, a genset breaker, and a mains breaker. It is compatible with a wide range of engines and can be configured for applications including engine drive, standalone genset control (off-grid/island mode), and Auto Mains Failure (AMF). With its battery charging and shelter temperature monitoring features, you can also use the SGC 420 Mk II for telecom base transceiver station (BTS) applications.

Designed to control and protect

With the SGC 420 Mk II, you get a wide range of control and protection features for engines and generators, including coolant temperature control, electrical monitoring, and grid voltage/frequency monitoring. The controller can automatically exercise the engine, and it can balance the running hours between two gensets. You can configure start sequences for engines with different dynamics, and the practical deep sleep function extends the battery life by suspending normal controller functions when the genset is off.

Flexible connection and communication options

The SGC 420 Mk II is a flexible controller that offers many options for your applications. It supports 1 and 5-ampere current transformers, and you can configure the controller for CAN bus and RS-485 Modbus communication. The controller has 9 digital inputs, 7 digital outputs, and 7 analogue inputs (5 x RMI & 2 x 4-20 mA / 0-5 VDC) that you can also configure as digital inputs, and you can configure the analogue inputs for any function you require.
