Lovato RGK750 is a 12/24 V DC Automatic Mains Failure gen-set controller with graphic display, CANbus, expandable I/O and IP65 front protection for automatic generator monitoring and mains-generator switching.
£435.46
The Lovato RGK750 is an advanced Automatic Mains Failure (AMF) generator set controller designed for automatic control, monitoring and protection of generating sets with mains-generator changeover management. As part of the Lovato RGK series of engine and generator controllers, it combines comprehensive electrical measurement, engine management and programmable control functions in a robust panel-mounted unit.
The RGK750 automatically monitors the mains supply and manages generator operation and mains-generator switching when required. Its 128 × 80 pixel backlit graphic LCD, function keys, status LEDs and built-in buzzer provide a clear operator interface, while advanced programmable inputs and outputs allow the controller to be configured for a wide variety of generator installations.
Designed for 12/24 V DC battery systems, the RGK750 measures generator and mains voltages from 100–480 V AC and supports three-phase 1 A or 5 A current transformer inputs. Integrated CANbus communication, front optical programming connectivity and two expansion slots for EXP modules provide extensive integration and expansion possibilities for modern generator control systems.
Automatic Mains Failure controllers such as the Lovato RGK750 continuously supervise the electrical supply and coordinate generator operation when mains power is unavailable. The controller manages the generator starting sequence and mains-generator switching logic while monitoring electrical and engine parameters, helping provide dependable standby power operation.
The RGK750 is designed for sophisticated generator installations requiring flexible control and communications. Programmable I/O, CANbus connectivity and two EXP expansion slots allow the controller to be adapted with additional digital I/O, static or relay outputs and compatible communication interfaces, making it suitable for both standard standby generator systems and more complex power control applications.
