The Senci SC-25YC-V3PH is a powerful three-phase diesel generator designed for reliable standby power. Delivering a power output of 20kW and a maximum output of 22kW, it is suitable for backup power only to commercial premises, workshops, agricultural use, construction sites and backup power installations.
Powered by a robust Yuchai YC4V45Z-D20 four-cylinder diesel engine, the SC-25YC-V3PH operates at a low engine speed of 1500rpm. Its water-cooled, four-stroke engine is designed for dependable operation during extended running periods, while turbocharging and an electronically controlled high-pressure common rail fuel system provide efficient and responsive engine performance.
The generator produces a 400V, 50Hz three-phase electrical supply and is fitted with a Senci SC-184F brushless alternator. Automatic Voltage Regulation helps maintain a stable electrical output as the connected load changes, making the generator suitable for powering a wide range of compatible electrical equipment.
A Deep Sea Electronics DSE6120 MKIII controller provides straightforward monitoring and control of the generator. The unit also includes a circuit breaker and is ATS-ready, allowing it to be incorporated into a suitable automatic standby power installation when connected and configured by a qualified electrician.
The heavy-duty generator set has a net weight of approximately 780kg and measures 2030mm long, 930mm wide and 1270mm high.
Please note that due to the size and weight of this item, offload will be required via forklift or similar telehandler. This is not included with the delivery and will have to be organised by the customer.
