Ricardo 50 kW diesel generator with a listed Ricardo R4105ZD four-cylinder, water-cooled diesel engine.
Send your load list, duty and site conditions to confirm the current data sheet, ATS or enclosure options and complete scope of supply.
The Ricardo 50 kW diesel generator listed by Alexerpower / Weifang Junwei Machinery Co., Ltd uses a Ricardo R4105ZD four-cylinder, water-cooled diesel engine. The published generator-set ratings are 50 kW / 62.5 kVA prime power and 55 kW / 68.75 kVA standby power at 50 Hz, with a listed engine speed of 1500 rpm.
The listing provides three-phase voltage options of 440 V, 415 V, 400 V and 380 V. Select the voltage and operating duty for your installation, and request the current data sheet for the complete engine-alternator assembly.
These reference data come from the existing Alexerpower product listing. Confirm the supplied engine version, electrical ratings, site conditions and included equipment before ordering.

The published kW and kVA pairs correspond to a power factor of 0.8. The 61.6 kW value in the original engine section is not the published electrical standby rating of this generator set. Request separate engine shaft-power and generator electrical-output data; do not substitute one for the other.
Include your required options in the enquiry so compatibility and the complete supply package can be checked:
The existing base description includes a belt-driven radiator fan with safety guard, vibration isolation, dry-type air filter, fuel filter and oil filter. Ask for the agreed bill of materials, installation drawing and service-access requirements.
The listing gives 50 kW / 62.5 kVA prime and 55 kW / 68.75 kVA standby at 50 Hz, corresponding to a power factor of 0.8. Confirm the approved duty definition and load profile. The standby figure should not be assumed to be an approved continuous output.
The original engine section includes a 61.6 kW maximum standby value. Its exact rating basis needs confirmation from the R4105ZD engine data sheet. The complete generator set is separately listed at 55 kW electrical standby power; the engine-section value should not be advertised as the generator’s electrical output.
The published choices are 440 V, 415 V, 400 V or 380 V, three-phase, 50 Hz, with the engine listed at 1500 rpm. For another voltage or a 60 Hz requirement, request a separately approved configuration and corresponding ratings rather than reusing the 50 Hz data.
The current product information does not provide a verified L/h fuel-consumption curve. Request complete generator-set consumption at your intended loads, with fuel specification and test conditions. Use that data and your operating schedule to assess fuel cost and tank capacity.
These are listed as options, so confirm the items included in the quotation. For an ATS, specify the switching arrangement and required controls. For an enclosure, request noise data with the load, enclosure type and measurement distance stated.
Ask for the current generator and engine data sheets, manuals, factory test report and model-specific documents required for your destination. Request written warranty terms with a clear start date, time and running-hour limits, coverage and exclusions, together with the agreed spare-parts list.
For construction, agricultural equipment or industrial backup-power enquiries, provide the actual loads and installation conditions. A 50 kW name alone does not establish suitability for every starting load or operating schedule.
The Cummins generator-set selection guide provides general background on ratings, load assessment and site conditions. Confirm the supplied Ricardo assembly’s specification using its own approved data sheet.
Contact Alexerpower with your load list and project requirements. Request the proposed engine and alternator details, electrical duty ratings, fuel-consumption data, installation drawing, current photographs, warranty terms and full scope of supply.
