11kVA Cummins Onan Diesel Generator 11 QD HDKBN

This Cummins Onan set is an 11kVA single phase diesel generator with an intermittent rating of 11.0 kW at 50Hz and 1500 rpm. Power comes from a 4-cycle, indirect-injection, water-cooled four cylinder diesel of 1498 cm³ that produces a maximum of 13.5 kW (18.1 hp) at 1500 rpm. The alternator is brushless and four-pole, with Class H insulation.

Key features

• A sound-controlled housing and sound shields are built into the set to reduce noise.
• Four-point semi-focalised mounting reduces the vibration passed into whatever the set is mounted on.
• Automatic glow plugs help the engine start from cold, and self-diagnostic capability helps with troubleshooting.
• Frequency regulation is isochronous with random variation within ±0.5%, and voltage regulation is ±1.5% from no load to rated load, so supply stays close to nominal as the load changes.
• The brushless alternator has no brushes to wear or replace.
• The starting battery is specified at 12V, 70 Ah and 540 CCA at -15°C, so a matching battery can be chosen to suit cold starts.

Fuel use runs from 0.9 litres an hour with no load to 4.0 litres an hour at full load. Output current is rated at 100/50 A at 110/220V, 95.7/47.8 A at 115/230V and 91.7/46 A at 120/240V. Output is derated for altitude and for high ambient temperature, so allow for the site conditions when you size the set.

What it will run

At 11.0 kW single phase, which is about 46 amps at 240V (11.0 kW divided by 240V), the set typically suits a workshop, site office or small business: lighting, fridges, power tools, pumps and a compressor. Add up the running load first, then allow for starting loads. Air conditioners, compressors and pumps can draw several times their running current as they start, and the largest motor often decides the size of set you need. Check the compliance plate on each appliance. Any connection to premises wiring must go through an inlet and changeover switch installed by a licensed electrician. Send us your load list and we will help you size the set.

The set suits small commercial premises, workshops, site facilities and other single phase installations that need standby or auxiliary power, particularly where a sound-controlled housing and low vibration matter.
