It is an ideal replacement for DSE4520mkII, an automatic power failure control module (utility). The controller's LCD screen can display the general alarm, electrical trip and stop alarm information, and monitor the engine speed, oil pressure, water temperature, oil level and generator frequency, voltage, current and power to provide complete engine and generator protection. The control panel supports both EFI and non-EFI engines for , natural gas and gasoline (generator frequency detection). With a variety of flexible input, output and protection functions, suitable for different application requirements. Users can set parameters via software or edit them on the front panel. Function: Can be configured as or automatic start control module Supports J1939-75 to ma sk CAN alarms Generator frequency and CAN detection speed Largest backlit graphic display of its kind All parameters can be set on the front panel or PC Rotating phase generator detection Three phase grid test Supports 600V cable voltage system (L-L) Equipment/load power monitoring (kW, , kVAr, pf) Cumulative power monitoring (kWh, kVAh, kVArh) Overload protection Equipment/load current detection and protection Fuel and cranking power (customizable when connected to EFI) 4 custom DC outputs 3 custom analog/digital inputs 4 custom digital inputs Custom hierarchical load output 3 tips for Engine maintenance Engine speed protection Engine running time sensor Engine preheating Preset engine start-stop cycles Engine start and stop idle control Level 4 standard engine instrument interface Battery voltage monitoring Start device when battery voltage is too low Adjust remote start input 2 protection parameters Complete alarm, trip and shutdo protection LCD alarm display 50 event records Colour:Black Material:ABS Package Contents: 1x Controller Only the above package content, other products are not included.
