5kVA Cummins Onan Diesel Generator QD5000

The QD 5000 is a commercial diesel generator set from the Cummins Onan QD series. Its engine is a Kubota Z482, a two-cylinder, four-cycle, liquid-cooled diesel of 479 cm³ with a 23:1 compression ratio. A brush-type alternator makes the power at a power factor of 1.0.

Key features

• An automatic glow plug preheats the engine for starting, so there is no manual preheat step.
• Self-diagnostics help trace faults, which makes fault-finding quicker.
• The switches and the coolant check and fill points are mounted on top, and a side door gives access for servicing.
• An enclosed muffler is part of the set, and the sound level is 68 dB(A) at 3 m (10 ft) at half load.
• Safeties protect against over-voltage, low oil pressure, over-temperature, over-speed and overload.
• A 4 amp battery charging circuit and fused DC circuits look after the starting system, and an hour meter records running time for service planning.
• Digital voltage regulation and an electronic governor hold voltage and frequency steady as the load changes.

Ratings apply up to 500 ft altitude and 85°F ambient, and output decreases above those limits, so a hot or elevated site needs a margin in the sizing.

What it will run

Size the set from the real load: add up what runs at the same time, then allow for the starting surge of motors and compressors, which typically draw several times their running current. Match the set's rating, phase and voltage to your equipment, and check each appliance's compliance plate. A small diesel set like this typically suits workshop tools, lighting, pumps and refrigeration on a small site or installation. Connection to a building's 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 QD 5000 suits commercial and trade users who want a diesel-driven set for workshops, site cabins, service installations and small premises.
