Baudouin 6M12G4D3/5 vs Perkins 1206A-E70TTAG2: 160 vs 180 kWe prime at 50 Hz
A 160 kWe requirement and a 180 kWe requirement produce different shortlists. Compare the prime rating first if the generator will supply a variable load for extended operation.
Quick comparison: matching documented ratings
Diesel · 50 Hz. Figures refer to the identified source configurations, not Haifeng test results. Confirm the exact build and site conditions before selection.
| Rating basis | Baudouin 6M12G4D3/5 | Perkins 1206A-E70TTAG2 |
|---|---|---|
| Standby · 50 Hz | 176 kWe | 200 kWe |
| Prime · 50 Hz | 160 kWe | 180 kWe |
Source scope and checks before selection
- The Baudouin catalog records 180 kWe standby, but the current manufacturer table lists 176. This comparison uses the manufacturer’s 176 kWe value.
- Confirm the exact Perkins build and site derating. Neither source establishes price, stock, efficiency or maintenance-cost superiority.
Which should you shortlist?
The Baudouin source lists 160 kWe prime / 176 kWe standby, while the Perkins sheet lists 180 / 200 kWe. For a prime load above 160 kWe, the documented Baudouin configuration is insufficient even before derating. At lower loads, obtain package-specific quotations and loading guidance rather than treating the higher output as an automatic advantage.
Three checks before requesting a quote
- Match the operating duty. Keep standby backup separate from prime variable-load operation. These 50 Hz ratings do not establish output at 60 Hz.
- Check the complete package: voltage, alternator, load steps, ambient temperature and altitude. Ask for the resulting site rating and test scope.
- Confirm support and documentation: exact engine suffix, serial-specific parts information, available service documents and destination-specific emissions evidence. A catalog label alone does not prove compliance.
Sources and comparison method
Reviewed 21 October 2026. This is a document and catalog comparison by Haifeng Machinery, an equipment supplier. Matching fuel, frequency and duty does not establish identical reference conditions or interchangeability. No independent test, price, stock or reliability ranking is claimed.

Can one replace the other?
A similar electrical rating is only a starting point. Mounting, coupling, cooling, controls, emissions and site requirements need a package-level review. Send the existing generator model or nameplate with your question.
