Compact Controller for Small Generator Sets Product overview This controller is designed for reliable starting, stopping, monitoring, fault display and parameter setting of small diesel, gasoline and gas generator sets. It features a dot matrix LCD that shows multiple faults at once and stops the generator set when operation is abnormal. All parameters can be changed using front panel buttons or by connecting to a PC via USB. Language options include Chinese and English, with additional languages available on request. Key benefits Reliable automatic control: automatic start and stop plus simultaneous fault display help protect the generator set and reduce downtime. Wide electrical compatibility: supports a wide DC supply range and large AC input range to suit varied generator systems. Low standby power: very low power consumption in standby and working modes for efficient operation. Flexible outputs: multiple relay outputs including programmable and noncontact relays provide flexible control for fuel, start and auxiliary functions. Easy configuration and monitoring: front buttons for quick onsite setup and USB PC interface for advanced programming and parameter backup. Compact, panelmount design: small footprint and standard cutout simplify installation in control panels. Main features and specifications Supply voltage: DC 8 to 36 V continuous Power consumption: standby at 24 V maximum 1 W; working at 24 V maximum 2 W AC voltage input: single phase twowire L to N input, 30 VAC to 360 VAC (phase to neutral) Speed sensor frequency input: 50 to 9000 Hz Generator frequency input: 50 Hz or 60 Hz Accumulated run time display: up to 9999.9 hours; minimum storage interval 6 minutes Display: dot matrix LCD with multifault display and automatic shut down on abnormal operation Languages: Chinese and English standard; additional languages configurable on request Programming: front panel buttons or PC via USB Relay outputs and inputs Fuel relay output: 1 Amp, DC positive supply voltage Start relay output: 1 Amp, DC positive supply voltage Programmable relay output 1: 1 Amp, DC positive supply voltage Programmable relay output 2: 1 Amp noncontact relay, configurable normally open or normally closed Programmable relay output 3: 1 Amp noncontact, normally open Switching value inputs: available when connected to battery Safety and environmental ratings Insulation strength: 1.5 kV AC applied between voltage and low voltage terminals; leakage current not more than 3 mA in 1 minute Operating temperature range: 25 to 65 C Storage temperature range: 40 to 85 C Protection level: IP54 when a waterproof rubber gasket is fitted between the controller and the panel Mechanical data Overall dimensions: 106 mm x 86 mm x 45 mm (panel) Panel cutout opening: 78 mm x 66 mm Weight: 0.25 kg Practical applications Standby and prime power control for small commercial buildings or retail outlets where automatic start, fault protection and logging are required. Remote telecom or monitoring shelters that need low standby power, compact size and reliable automatic control. Rental or portable generator sets requiring flexible programmable outputs for different accessory configurations. Installation and configuration notes Designed for panel mounting using the standard 78 mm x 66 mm cutout. Add the supplied waterproof rubber gasket during installation to achieve IP54 protection rating. Use the front panel buttons for basic setup and routine changes. For advanced configuration, connect the controller to a PC via USB to upload or download parameter sets and language files. This controller provides a compact, low power, and flexible control solution for small generator sets, with comprehensive fault monitoring and multiple configurable outputs to match a variety of installation requirements.
